# Docker Hub Enterprise Administrator's Guide
|
||||||
|
|
||||||
|
This guide covers tasks and functions an administrator of Docker Hub Enterprise
|
||||||
|
(DHE) will need to know about, such as reporting, logging, system management,
|
||||||
|
performance metrics, etc.
|
||||||
|
For tasks DHE users need to accomplish, such as using DHE to push and pull
|
||||||
|
images, please visit the [User's Guide](./userguide).
|
||||||
|
|
||||||
|
## Reporting
|
||||||
|
|
||||||
|
### System Health
|
||||||
|
|
||||||
|
![System Health page</admin/metrics/>](../assets/admin-metrics.png)
|
||||||
|
|
||||||
|
The "System Health" tab displays resource utilization metrics for the DHE host
|
||||||
|
as well as for each of its contained services. The CPU and RAM usage meters at
|
||||||
|
the top indicate overall resource usage for the host, while detailed time-series
|
||||||
|
charts are provided below for each service. You can mouse-over the charts or
|
||||||
|
meters to see detailed data points.
|
||||||
|
|
||||||
|
Clicking on a service name (i.e., "load_balancer", "admin_server", etc.) will
|
||||||
|
display the network, CPU, and memory (RAM) utilization data for the specified
|
||||||
|
service. See below for a
|
||||||
|
[detailed explanation of the available services](#services).
|
||||||
|
|
||||||
|
### Logs
|
||||||
|
|
||||||
|
![System Logs page</admin/logs/>](../assets/admin-logs.png)
|
||||||
|
|
||||||
|
Click the "Logs" tab to view all logs related to your DHE instance. You will see
|
||||||
|
log sections on this page for each service in your DHE instance. Older or newer
|
||||||
|
logs can be loaded by scrolling up or down. See below for a
|
||||||
|
[detailed explanation of the available services](#services).
|
||||||
|
|
||||||
|
DHE's log files can be found on the host in `/usr/local/etc/dhe/logs/`. The
|
||||||
|
files are limited to a maximum size of 64mb. They are rotated every two weeks,
|
||||||
|
when the aggregator sends logs to the collection server, or they are rotated if
|
||||||
|
a logfile would exceed 64mb without rotation. Log files are named `<component
|
||||||
|
name>-<timestamp at rotation>`, where the "component name" is the service it
|
||||||
|
provides (`manager`, `admin-server`, etc.).
|
||||||
|
|
||||||
|
### Usage statistics and crash reports
|
||||||
|
|
||||||
|
During normal use, DHE generates usage statistics and crash reports. This
|
||||||
|
information is collected by Docker, Inc. to help us prioritize features, fix
|
||||||
|
bugs, and improve our products. Specifically, Docker, Inc. collects the
|
||||||
|
following information:
|
||||||
|
|
||||||
|
* Error logs
|
||||||
|
* Crash logs
|
||||||
|
|
||||||
|
## Emergency access to the DHE admin web interface
|
||||||
|
|
||||||
|
If your authenticated or public access to the DHE web interface has stopped
|
||||||
|
working, but your DHE admin container is still running, you can add an
|
||||||
|
[ambassador container](https://docs.docker.com/articles/ambassador_pattern_linking/)
|
||||||
|
to get temporary unsecure access to it by running:
|
||||||
|
|
||||||
|
$ docker run --rm -it --link docker_hub_enterprise_admin_server:admin -p 9999:80 svendowideit/ambassador
|
||||||
|
|
||||||
|
> **Note:** This guide assumes you can run Docker commands from a machine where
|
||||||
|
> you are a member of the `docker` group, or have root privileges. Otherwise,
|
||||||
|
> you may need to add `sudo` to the example command above.
|
||||||
|
|
||||||
|
This will give you access on port `9999` on your DHE server - `http://<dhe-host-ip>:9999/admin/`.
|
||||||
|
|
||||||
|
## Services
|
||||||
|
|
||||||
|
DHE runs several Docker services which are essential to its reliability and
|
||||||
|
usability. The following services are included; you can see their details by
|
||||||
|
running queries on the [System Health](#system-health) and [Logs](#logs) pages:
|
||||||
|
|
||||||
|
* `admin_server`: Used for displaying system health, performing upgrades,
|
||||||
|
configuring settings, and viewing logs.
|
||||||
|
* `load_balancer`: Used for maintaining high availability by distributing load
|
||||||
|
to each image storage service (`image_storage_X`).
|
||||||
|
* `log_aggregator`: A microservice used for aggregating logs from each of the
|
||||||
|
other services. Handles log persistence and rotation on disk.
|
||||||
|
* `image_storage_X`: Stores Docker images using the [Docker Registry HTTP API V2](https://github.com/docker/distribution/blob/master/doc/SPEC.md). Typically,
|
||||||
|
multiple image storage services are used in order to provide greater uptime and
|
||||||
|
faster, more efficient resource utilization.
|
||||||
|
|
||||||
|
## DHE system management
|
||||||
|
|
||||||
|
The `dockerhubenterprise/manager` image is used to control the DHE system. This
|
||||||
|
image uses the Docker socket to orchestrate the multiple services that comprise
|
||||||
|
DHE.
|
||||||
|
|
||||||
|
$ sudo bash -c "$(sudo docker run dockerhubenterprise/manager [COMMAND])"
|
||||||
|
|
||||||
|
Supported commands are: `install`, `start`, `stop`, `restart`, `status`, and
|
||||||
|
`upgrade`.
|
||||||
|
|
||||||
|
> **Note**: `sudo` is needed for `dockerhubenterprise/manager` commands to
|
||||||
|
> ensure that the Bash script is run with full access to the Docker host.
|
||||||
|
|
||||||
|
## Next Steps
|
||||||
|
|
||||||
|
For information on installing DHE, take a look at the [Installation instructions](./install.md).

# Configuration options
|
||||||
|
|
||||||
|
This page will help you properly configure Docker Hub Enterprise (DHE) so it can
|
||||||
|
run in your environment.
|
||||||
|
|
||||||
|
Start with DHE loaded in your browser and click the "Settings" tab to view
|
||||||
|
configuration options. You'll see options for configuring:
|
||||||
|
|
||||||
|
* Domains and ports
|
||||||
|
* Security settings
|
||||||
|
* Storage settings
|
||||||
|
* Authentication settings
|
||||||
|
* Your DHE license
|
||||||
|
|
||||||
|
## Domains and Ports
|
||||||
|
|
||||||
|
![Domain and Ports page</admin/settings#http>](../assets/admin-settings-http.png)
|
||||||
|
|
||||||
|
* *Domain Name*: **required**; defaults to an empty string, the fully qualified domain name assigned to the DHE host.
|
||||||
|
* *Load Balancer HTTP Port*: defaults to 80, used as the entry point for the image storage service. To see load balancer status, you can query
|
||||||
|
http://<dhe-host>/load_balancer_status.
|
||||||
|
* *Load Balancer HTTPS Port*: defaults to 443, used as the secure entry point
|
||||||
|
for the image storage service.
|
||||||
|
* *HTTP_PROXY*: defaults to an empty string, proxy server for HTTP requests.
|
||||||
|
* *HTTPS_PROXY*: defaults to an empty string, proxy server for HTTPS requests.
|
||||||
|
* *NO_PROXY*: defaults to an empty string, proxy bypass for HTTP and HTTPS requests.
|
||||||
|
|
||||||
|
|
||||||
|
> **Note**: If you need DHE to re-generate a self-signed certificate at some
|
||||||
|
> point, you'll need to first delete `/usr/local/etc/dhe/ssl/server.pem`, and
|
||||||
|
> then restart the DHE containers, either by changing and saving the "Domain Name",
|
||||||
|
> or using `bash -c "$(docker run dockerhubenterprise/manager restart)"`.
|
||||||
|
|
||||||
|
|
||||||
|
## Security
|
||||||
|
|
||||||
|
![Security settings page</admin/settings#security>](../assets/admin-settings-security.png)
|
||||||
|
|
||||||
|
* *SSL Certificate*: Used to enter the hash (string) from the SSL Certificate.
|
||||||
|
This cert must be accompanied by its private key, entered below.
|
||||||
|
* *Private Key*: The hash from the private key associated with the provided
|
||||||
|
SSL Certificate (as a standard x509 key pair).
|
||||||
|
|
||||||
|
In order to run, DHE requires encrypted communications via HTTPS/SSL between (a) the DHE registry and your Docker Engine(s), and (b) between your web browser and the DHE admin server. There are a few options for setting this up:
|
||||||
|
|
||||||
|
1. You can use the self-signed certificate DHE generates by default.
|
||||||
|
2. You can generate your own certificates using a public service or your enterprise's infrastructure. See the [Generating SSL certificates](#generating-ssl-certificates) section for the options available.
|
||||||
|
|
||||||
|
If you are generating your own certificates, you can install them by following the instructions for
|
||||||
|
[Adding your own registry certificates to DHE](#adding-your-own-registry-certificates-to-dhe).
|
||||||
|
|
||||||
|
On the other hand, if you choose to use the DHE-generated certificates, or the
|
||||||
|
certificates you generate yourself are not trusted by your client Docker hosts,
|
||||||
|
you will need to do one of the following:
|
||||||
|
|
||||||
|
* [Install a registry certificate on all of your client Docker daemons](#installing-registry-certificates-on-client-docker-daemons),
|
||||||
|
|
||||||
|
* Set your [client Docker daemons to run with an unconfirmed connection to the registry](#if-you-cant-install-the-certificates).
|
||||||
|
|
||||||
|
### Generating SSL certificates
|
||||||
|
|
||||||
|
There are three basic approaches to generating certificates:
|
||||||
|
|
||||||
|
1. Most enterprises will have private key infrastructure (PKI) in place to
|
||||||
|
generate keys. Consult with your security team or whomever manages your private
|
||||||
|
key infrastructure. If you have this resource available, Docker recommends you
|
||||||
|
use it.
|
||||||
|
|
||||||
|
2. If your enterprise can't provide keys, you can use a public Certificate
|
||||||
|
Authority (CA) like "InstantSSL.com" or "RapidSSL.com" to generate a
|
||||||
|
certificate. If your certificates are generated using a globally trusted
|
||||||
|
Certificate Authority, you won't need to install them on all of your
|
||||||
|
client Docker daemons.
|
||||||
|
|
||||||
|
3. Use the self-signed registry certificate generated by DHE, and install it
|
||||||
|
onto the client Docker daemon hosts as shown below.
|
||||||
|
|
||||||
|
### Adding your own Registry certificates to DHE
|
||||||
|
|
||||||
|
Whichever method you use to generate certificates, once you have them
|
||||||
|
you can set up your DHE server to use them by navigating to the "Settings" page,
|
||||||
|
going to "Security," and putting the SSL Certificate text (including all
|
||||||
|
intermediate Certificates, starting with the host) into the
|
||||||
|
"SSL Certificate" edit box, and the previously generated Private key into
|
||||||
|
the "SSL Private Key" edit box.
|
||||||
|
|
||||||
|
Click the "Save" button, and then wait for the DHE Admin site to restart and
|
||||||
|
reload. It should now be using the new certificate.
|
||||||
|
|
||||||
|
Once the "Security" page has reloaded, it will show `#` hashes instead of the
|
||||||
|
certificate text you pasted in.
|
||||||
|
|
||||||
|
If your certificate is signed by a chain of Certificate Authorities that are
|
||||||
|
already trusted by your Docker daemon servers, you can skip the "Installing
|
||||||
|
registry certificates" step below.
|
||||||
|
|
||||||
|
### Installing Registry certificates on client Docker daemons
|
||||||
|
|
||||||
|
If your certificates do not have a trusted Certificate Authority, you will need
|
||||||
|
to install them on each client Docker daemon host.
|
||||||
|
|
||||||
|
The procedure for installing the DHE certificates on each Linux distribution has
|
||||||
|
slightly different steps, as shown below.
|
||||||
|
|
||||||
|
You can test this certificate using `curl`:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ curl https://dhe.yourdomain.com/v2/
|
||||||
|
curl: (60) SSL certificate problem: self signed certificate
|
||||||
|
More details here: http://curl.haxx.se/docs/sslcerts.html
|
||||||
|
|
||||||
|
curl performs SSL certificate verification by default, using a "bundle"
|
||||||
|
of Certificate Authority (CA) public keys (CA certs). If the default
|
||||||
|
bundle file isn't adequate, you can specify an alternate file
|
||||||
|
using the --cacert option.
|
||||||
|
If this HTTPS server uses a certificate signed by a CA represented in
|
||||||
|
the bundle, the certificate verification probably failed due to a
|
||||||
|
problem with the certificate (it might be expired, or the name might
|
||||||
|
not match the domain name in the URL).
|
||||||
|
If you'd like to turn off curl's verification of the certificate, use
|
||||||
|
the -k (or --insecure) option.
|
||||||
|
|
||||||
|
$ curl --cacert /usr/local/etc/dhe/ssl/server.pem https://dhe.yourdomain.com/v2/
|
||||||
|
{"errors":[{"code":"UNAUTHORIZED","message":"access to the requested resource is not authorized","detail":null}]}
|
||||||
|
```
|
||||||
|
|
||||||
|
Continue by following the steps corresponding to your chosen OS.
|
||||||
|
|
||||||
|
#### Ubuntu/Debian
|
||||||
|
|
||||||
|
```
|
||||||
|
$ export DOMAIN_NAME=dhe.yourdomain.com
|
||||||
|
$ openssl s_client -connect $DOMAIN_NAME:443 -showcerts </dev/null 2>/dev/null | openssl x509 -outform PEM | tee /usr/local/share/ca-certificates/$DOMAIN_NAME.crt
|
||||||
|
$ update-ca-certificates
|
||||||
|
Updating certificates in /etc/ssl/certs... 1 added, 0 removed; done.
|
||||||
|
Running hooks in /etc/ca-certificates/update.d....done.
|
||||||
|
$ service docker restart
|
||||||
|
docker stop/waiting
|
||||||
|
docker start/running, process 29291
|
||||||
|
```
|
||||||
|
|
||||||
|
#### RHEL
|
||||||
|
|
||||||
|
```
|
||||||
|
$ export DOMAIN_NAME=dhe.yourdomain.com
|
||||||
|
$ openssl s_client -connect $DOMAIN_NAME:443 -showcerts </dev/null 2>/dev/null | openssl x509 -outform PEM | tee /etc/pki/ca-trust/source/anchors/$DOMAIN_NAME.crt
|
||||||
|
$ update-ca-trust
|
||||||
|
$ /bin/systemctl restart docker.service
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Boot2Docker 1.6.0
|
||||||
|
|
||||||
|
Install the CA cert (or the auto-generated cert) by adding the following to
|
||||||
|
your `/var/lib/boot2docker/bootsync.sh`:
|
||||||
|
|
||||||
|
```
|
||||||
|
#!/bin/sh
|
||||||
|
|
||||||
|
cat /var/lib/boot2docker/server.pem >> /etc/ssl/certs/ca-certificates.crt
|
||||||
|
```
|
||||||
|
|
||||||
|
|
||||||
|
Then get the certificate from the new DHE server using:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ openssl s_client -connect dhe.yourdomain.com:443 -showcerts </dev/null 2>/dev/null | openssl x509 -outform PEM | sudo tee -a /var/lib/boot2docker/server.pem
|
||||||
|
```
|
||||||
|
|
||||||
|
If your certificate chain is complicated, you may want to use the changes in
|
||||||
|
[Pull request 807](https://github.com/boot2docker/boot2docker/pull/807/files)
|
||||||
|
|
||||||
|
Now you can either reboot your Boot2Docker virtual machine, or run the following to
|
||||||
|
install the server certificate, and then restart the Docker daemon.
|
||||||
|
|
||||||
|
```
|
||||||
|
$ sudo chmod 755 /var/lib/boot2docker/bootsync.sh
|
||||||
|
$ sudo /var/lib/boot2docker/bootsync.sh
|
||||||
|
$ sudo /etc/init.d/docker restart`.
|
||||||
|
```
|
||||||
|
|
||||||
|
### If you can't install the certificates
|
||||||
|
|
||||||
|
If for some reason you can't install the certificate chain on a client Docker host,
|
||||||
|
or your certificates do not have a global CA, you can configure your Docker daemon to run in "insecure" mode. This is done by adding an extra flag,
|
||||||
|
`--insecure-registry host-ip|domain-name`, to your client Docker daemon startup flags.
|
||||||
|
You'll need to restart the Docker daemon for the change to take effect.
|
||||||
|
|
||||||
|
This flag means that the communications between your Docker client and the DHE
|
||||||
|
Registry server are still encrypted, but the client Docker daemon is not
|
||||||
|
confirming that the Registry connection is not being hijacked or diverted.
|
||||||
|
|
||||||
|
> **Note**: If you enter a "Domain Name" into the "Security" settings, it needs
|
||||||
|
> to be DNS resolvable on any client Docker daemons that are running in
|
||||||
|
> "insecure-registry" mode.
|
||||||
|
|
||||||
|
To set the flag, follow the directions below for your operating system.
|
||||||
|
|
||||||
|
#### Ubuntu
|
||||||
|
|
||||||
|
On Ubuntu 14.04 LTS, you customize the Docker daemon configuration with the
|
||||||
|
`/etc/defaults/docker` file.
|
||||||
|
|
||||||
|
Open or create the `/etc/defaults/docker` file, and add the
|
||||||
|
`--insecure-registry` flag to the `DOCKER_OPTS` setting (which may need to be
|
||||||
|
added or uncommented) as follows:
|
||||||
|
|
||||||
|
```
|
||||||
|
DOCKER_OPTS="--insecure-registry dhe.yourdomain.com"
|
||||||
|
```
|
||||||
|
|
||||||
|
Then restart the Docker daemon with `sudo service docker restart`.
|
||||||
|
|
||||||
|
#### RHEL
|
||||||
|
|
||||||
|
On RHEL, you customize the Docker daemon configuration with the
|
||||||
|
`/etc/sysconfig/docker` file.
|
||||||
|
|
||||||
|
Open or create the `/etc/sysconfig/docker` file, and add the
|
||||||
|
`--insecure-registry` flag to the `OPTIONS` setting (which may need to be
|
||||||
|
added or uncommented) as follows:
|
||||||
|
|
||||||
|
```
|
||||||
|
OPTIONS="--insecure-registry dhe.yourdomain.com"
|
||||||
|
```
|
||||||
|
|
||||||
|
Then restart the Docker daemon with `sudo service docker restart`.
|
||||||
|
|
||||||
|
### Boot2Docker
|
||||||
|
|
||||||
|
On Boot2Docker, you customize the Docker daemon configuration with the
|
||||||
|
`/var/lib/boot2docker/profile` file.
|
||||||
|
|
||||||
|
Open or create the `/var/lib/boot2docker/profile` file, and add an `EXTRA_ARGS`
|
||||||
|
setting as follows:
|
||||||
|
|
||||||
|
```
|
||||||
|
EXTRA_ARGS="--insecure-registry dhe.yourdomain.com"
|
||||||
|
```
|
||||||
|
|
||||||
|
Then restart the Docker daemon with `sudo /etc/init.d/docker restart`.
|
||||||
|
|
||||||
|
## Image Storage Configuration
|
||||||
|
|
||||||
|
DHE offers multiple methods for image storage, which are defined using specific
|
||||||
|
storage drivers. Image storage can be local, remote, or on a cloud service such
|
||||||
|
as S3. Storage drivers can be added or customized via the DHE storage driver
|
||||||
|
API.
|
||||||
|
|
||||||
|
![Storage settings page</admin/settings#storage>](../assets/admin-settings-storage.png)
|
||||||
|
|
||||||
|
* *Yaml configuration file*: This file (`/usr/local/etc/dhe/storage.yml`) is
|
||||||
|
used to configure the image storage services. The editable text of the file is
|
||||||
|
displayed in the dialog box. The schema of this file is identical to that used
|
||||||
|
by the [Registry 2.0](http://docs.docker.com/registry/configuration/).
|
||||||
|
* If you are using the file system driver to provide local image storage, you will need to specify a root directory which will get mounted as a sub-path of
|
||||||
|
`/var/local/dhe/image-storage`. The default value of this root directory is
|
||||||
|
`/local`, so the full path to it is `/var/local/dhe/image-storage/local`.
|
||||||
|
|
||||||
|
> **Note:**
|
||||||
|
> Saving changes you've made to settings will restart the Docker Hub Enterprise
|
||||||
|
> instance. The restart may cause a brief interruption for users of the image
|
||||||
|
> storage system.
|
||||||
|
|
||||||
|
## Authentication
|
||||||
|
|
||||||
|
The current authentication methods are `None`, `Basic` and `LDAP`.
|
||||||
|
|
||||||
|
The `Basic` setting includes:
|
||||||
|
|
||||||
|
![Basic authentication settings page</admin/settings#auth>](../assets/admin-settings-authentication-basic.png)
|
||||||
|
|
||||||
|
* A button to add one user, or to upload a CSV file containing username,
|
||||||
|
password pairs
|
||||||
|
* A DHE website Administrator Filter, allowing you to either
|
||||||
|
* * 'Allow all authenticated users' to log into the DHE admin web interface, or
|
||||||
|
* * 'Whitelist usernames', which allows you to restrict access to the web
|
||||||
|
interface to the listed set of users.
|
||||||
|
|
||||||
|
The `LDAP` setting includes:
|
||||||
|
|
||||||
|
![LDAP authentication settings page</admin/settings#auth>](../assets/admin-settings-authentication-ldap.png)
|
||||||
|
|
||||||
|
* *Use StartTLS*: defaults to unchecked, check to enable StartTLS
|
||||||
|
* *LDAP Server URL*: **required**; defaults to null, LDAP server URL (e.g., - ldap://example.com)
|
||||||
|
* *User Base DN*: **required**; defaults to null, user base DN in the form
|
||||||
|
(e.g., - dc=example,dc=com)
|
||||||
|
* *User Login Attribute*: **required**; defaults to null, user login attribute
|
||||||
|
(e.g., - uid or sAMAccountName)
|
||||||
|
* *Search User DN*:** required**; defaults to null, search user DN
|
||||||
|
(e.g., - domain\username)
|
||||||
|
* *Search User Password*: **required**; defaults to null, search user password
|
||||||
|
* A *DHE Registry User filter*, allowing you to either
|
||||||
|
* * 'Allow all authenticated users' to push or pull any images, or
|
||||||
|
* * 'Filter LDAP search results', which allows you to restrict DHE registry pull
|
||||||
|
and push to users matching the LDAP filter,
|
||||||
|
* * 'Whitelist usernames', which allows you to restrict DHE registry pull and
|
||||||
|
push to the listed set of users.
|
||||||
|
* A *DHE website Administrator filter*, allowing you to either
|
||||||
|
* * 'Allow all authenticated users' to log into the DHE admin web interface, or
|
||||||
|
* * 'Filter LDAP search results', which allows you to restrict DHE admin web access to users matching the LDAP filter,
|
||||||
|
* * 'Whitelist usernames', which allows you to restrict access to the web interface to the listed set of users.
|
||||||
|
|
||||||

# Overview
|
||||||
|
|
||||||
|
Docker Hub Enterprise (DHE) lets you run and manage your own Docker image
|
||||||
|
storage service, securely on your own infrastructure behind your company
|
||||||
|
firewall. This allows you to securely store, push, and pull the images used by
|
||||||
|
your enterprise to build, ship, and run applications. DHE also provides
|
||||||
|
monitoring and usage information to help you understand the workloads being
|
||||||
|
placed on it.
|
||||||
|
|
||||||
|
Specifically, DHE provides:
|
||||||
|
|
||||||
|
* An image registry to store, manage, and collaborate on Docker images
|
||||||
|
* Pluggable storage drivers
|
||||||
|
* Configuration options to let you run DHE in your particular enterprise
|
||||||
|
environment.
|
||||||
|
* Easy, transparent upgrades
|
||||||
|
* Logging, usage and system health metrics
|
||||||
|
|
||||||
|
DHE is perfect for:
|
||||||
|
|
||||||
|
* Providing a secure, on-premise development environment
|
||||||
|
* Creating a streamlined build pipeline
|
||||||
|
* Building a consistent, high-performance test/QA environment
|
||||||
|
* Managing image deployment
|
||||||
|
|
||||||
|
DHE is built on [version 2 of the Docker registry](https://github.com/docker/distribution).

# Install
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
This document describes the process of obtaining, installing, and securing
|
||||||
|
Docker Hub Enterprise (DHE). DHE is installed from Docker containers. Once
|
||||||
|
installed, you will need to select a method of securing it. This doc will
|
||||||
|
explain the options you have for security and help you find the resources needed
|
||||||
|
to configure it according to your chosen method. More configuration details can
|
||||||
|
be found in the [DHE Configuration page](./configuration.md).
|
||||||
|
|
||||||
|
Specifically, installation requires completion of these steps, in order:
|
||||||
|
|
||||||
|
1. Acquire a license by purchasing DHE or requesting a trial license.
|
||||||
|
2. Install the commercially supported Docker Engine.
|
||||||
|
3. Install DHE
|
||||||
|
4. Add your license to your DHE instance
|
||||||
|
|
||||||
|
## Licensing
|
||||||
|
|
||||||
|
In order to run DHE, you will need to acquire a license, either by purchasing
|
||||||
|
DHE or requesting a trial license. The license will be associated with your
|
||||||
|
Docker Hub account or Docker Hub organization (so if you don't have an account,
|
||||||
|
you'll need to set one up, which can be done at the same time as your license
|
||||||
|
request). To get your license or start your trial, please contact our
|
||||||
|
[sales department](mailto:sales@docker.com). Upon completion of your purchase or
|
||||||
|
request, you will receive an email with further instructions for licensing your
|
||||||
|
copy of DHE.
|
||||||
|
|
||||||
|
## Prerequisites
|
||||||
|
|
||||||
|
DHE requires the following:
|
||||||
|
|
||||||
|
* Commercially supported Docker Engine 1.6.0 or later running on an
|
||||||
|
Ubuntu 14.04 LTS, RHEL 7.1 or RHEL 7.0 host. (See below for instructions on how
|
||||||
|
to install the commercially supported Docker Engine.)
|
||||||
|
|
||||||
|
> **Note:** In order to remain in compliance with your DHE support agreement,
|
||||||
|
> you must use the current version of commercially supported Docker Engine.
|
||||||
|
> Running the regular, open source version of Engine is **not** supported.
|
||||||
|
|
||||||
|
* Your Docker daemon needs to be listening to the Unix socket (the default) so
|
||||||
|
that it can be bind-mounted into the DHE management containers, allowing
|
||||||
|
DHE to manage itself and its updates. For this reason, your DHE host will also
|
||||||
|
need internet connectivity so it can access the updates.
|
||||||
|
|
||||||
|
* Your host also needs to have TCP ports `80` and `443` available for the DHE
|
||||||
|
container port mapping.
|
||||||
|
|
||||||
|
* You will also need the Docker Hub user-name and password used when obtaining
|
||||||
|
the DHE license (or the user-name of an administrator of the Hub organization
|
||||||
|
that obtained an Enterprise license).
|
||||||
|
|
||||||
|
## Installing the Commercially Supported Docker Engine
|
||||||
|
|
||||||
|
Since DHE is installed using Docker, the commercially supported Docker Engine
|
||||||
|
must be installed first. This is done with an RPM or DEB repository, which you
|
||||||
|
set up using a Bash script downloaded from the [Docker Hub](https://hub.docker.com).
|
||||||
|
|
||||||
|
### Download the commercially supported Docker Engine installation script
|
||||||
|
|
||||||
|
To download the commercially supported Docker Engine Bash installation script,
|
||||||
|
log in to the [Docker Hub](https://hub.docker.com) with the user-name used to
|
||||||
|
obtain your license . Once you're logged in, go to the
|
||||||
|
["Enterprise Licenses"](https://registry.hub.docker.com/account/licenses/) page
|
||||||
|
in your Hub account's "Settings" section.
|
||||||
|
|
||||||
|
Select your intended host operating system from the "Download CS Engine" drop-
|
||||||
|
down at the top right of the page and then, once the Bash setup script is
|
||||||
|
downloaded, follow the steps below appropriate for your chosen OS.
|
||||||
|
|
||||||
|
![Docker Hub Docker engine install dropdown](../assets/docker-hub-org-enterprise-license-CSDE-dropdown.png)
|
||||||
|
|
||||||
|
### RHEL 7.0/7.1 installation
|
||||||
|
|
||||||
|
First, copy the downloaded Bash setup script to your RHEL host. Next, run the
|
||||||
|
following to install commercially supported Docker Engine and its dependencies,
|
||||||
|
and then start the Docker daemon:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ sudo yum update && sudo yum upgrade
|
||||||
|
$ chmod 755 docker-cs-engine-rpm.sh
|
||||||
|
$ sudo ./docker-cs-engine-rpm.sh
|
||||||
|
$ sudo yum install docker-engine-cs
|
||||||
|
$ sudo systemctl enable docker.service
|
||||||
|
$ sudo systemctl start docker.service
|
||||||
|
```
|
||||||
|
|
||||||
|
In order to simplify using Docker, you can get non-sudo access to the Docker
|
||||||
|
socket by adding your user to the `docker` group, then logging out and back in
|
||||||
|
again:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ sudo usermod -a -G docker $USER
|
||||||
|
$ exit
|
||||||
|
```
|
||||||
|
|
||||||
|
> **Note**: you may need to reboot your server to update its RHEL kernel.
|
||||||
|
|
||||||
|
### Ubuntu 14.04 LTS installation
|
||||||
|
|
||||||
|
First, copy the downloaded Bash setup script to your Ubuntu host. Next, run the
|
||||||
|
following to install commercially supported Docker Engine and its dependencies:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ sudo apt-get update && sudo apt-get upgrade
|
||||||
|
$ chmod 755 docker-cs-engine-deb.sh
|
||||||
|
$ sudo ./docker-cs-engine-deb.sh
|
||||||
|
$ sudo apt-get install docker-engine-cs
|
||||||
|
```
|
||||||
|
|
||||||
|
In order to simplify using Docker, you can get non-sudo access to the Docker
|
||||||
|
socket by adding your user to the `docker` group, then logging out and back in
|
||||||
|
again:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ sudo usermod -a -G docker $USER
|
||||||
|
$ exit
|
||||||
|
```
|
||||||
|
|
||||||
|
> **Note**: you may need to reboot your server to update its LTS kernel.
|
||||||
|
|
||||||
|
## Installing Docker Hub Enterprise
|
||||||
|
|
||||||
|
Once the commercially supported Docker Engine is installed, you can install DHE
|
||||||
|
itself. DHE is a self-installing application built and distributed using Docker
|
||||||
|
and the [Docker Hub](https://registry.hub.docker.com/). It is able to restart
|
||||||
|
and reconfigure itself using the Docker socket that is bind-mounted to its
|
||||||
|
container.
|
||||||
|
|
||||||
|
|
||||||
|
Start installing DHE by running the "dockerhubenterprise/manager" container:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ sudo bash -c "$(sudo docker run dockerhubenterprise/manager install)"
|
||||||
|
```
|
||||||
|
|
||||||
|
> **Note**: `sudo` is needed for `dockerhubenterprise/manager` commands to
|
||||||
|
> ensure that the Bash script is run with full access to the Docker host.
|
||||||
|
|
||||||
|
You can also find this command on the "Enterprise Licenses" section of your Hub
|
||||||
|
user profile. The command will execute a shell script that creates the needed
|
||||||
|
directories and then runs Docker to pull DHE's images and run its containers.
|
||||||
|
|
||||||
|
Depending on your internet connection, this process may take several minutes to
|
||||||
|
complete.
|
||||||
|
|
||||||
|
A successful installation will pull a large number of Docker images and should
|
||||||
|
display output similar to:
|
||||||
|
|
||||||
|
```
|
||||||
|

```
|
||||||
|
|
||||||
|
Once this process completes, you should be able to manage and configure your DHE
|
||||||
|
instance by pointing your browser to `https://<host-ip>/`.
|
||||||
|
|
||||||
|
Your browser will warn you that this is an unsafe site, with a self-signed,
|
||||||
|
untrusted certificate. This is normal and expected; allow this connection
|
||||||
|
temporarily.
|
||||||
|
|
||||||
|
### Setting the DHE Domain Name
|
||||||
|
|
||||||
|
The DHE Administrator site will also warn that the "Domain Name" is not set. Go
|
||||||
|
to the "Settings" tab, and set the "Domain Name" to the full host-name of your
|
||||||
|
DHE server.
|
||||||
|
Hitting the "Save and Restart DHE Server" button will generate a new certificate, which will be used
|
||||||
|
by both the DHE Administrator web interface and the DHE Registry server.
|
||||||
|
|
||||||
|
After the server restarts, you will again need to allow the connection to the untrusted DHE web admin site.
|
||||||
|
|
||||||
|
![http settings page</admin/settings#http>](../assets/admin-settings-http-unlicensed.png)
|
||||||
|
|
||||||
|
Lastly, you will see a warning notifying you that this instance of DHE is
|
||||||
|
unlicensed. You'll correct this in the next step.
|
||||||
|
|
||||||
|
### Add your license
|
||||||
|
|
||||||
|
The DHE registry services will not start until you add your license.
|
||||||
|
To do that, you'll first download your license from the Docker Hub and then
|
||||||
|
upload it to your DHE web admin server. Follow these steps:
|
||||||
|
|
||||||
|
1. If needed, log back into the [Docker Hub](https://hub.docker.com)
|
||||||
|
using the user-name you used when obtaining your license. Go to "Settings" (in
|
||||||
|
the menu under your user-name, top right) to get to your account settings, and
|
||||||
|
then click on "Enterprise Licenses" in the side bar at left.
|
||||||
|
|
||||||
|
2. You'll see a list of available licenses. Click on the download button to
|
||||||
|
obtain the license file you'd like to use.
|
||||||
|
![Download DHE license](../assets/docker-hub-org-enterprise-license.png)
|
||||||
|
|
||||||
|
3. Next, go to your DHE instance in your browser and click on the Settings tab
|
||||||
|
and then the "License" tab. Click on the "Upload license file" button, which
|
||||||
|
will open a standard file browser. Locate and select the license file you
|
||||||
|
downloaded in step 2, above. Approve the selection to close the dialog.
|
||||||
|
![http settings page</admin/settings#license>](../assets/admin-settings-license.png)
|
||||||
|
|
||||||
|
4. Click the "Save and Restart DHE" button, which will quit DHE and then restart it, registering
|
||||||
|
the new license.
|
||||||
|
|
||||||
|
5. Verify the acceptance of the license by confirming that the "unlicensed copy"
|
||||||
|
warning is no longer present.
|
||||||
|
|
||||||
|
### Securing DHE
|
||||||
|
|
||||||
|
Securing DHE is **required**. You will not be able to push or pull from DHE until you secure it.
|
||||||
|
|
||||||
|
There are several options and methods for securing DHE. For more information,
|
||||||
|
see the [configuration documentation](./configuration.md#security)
|
||||||
|
|
||||||
|
### Using DHE to push and pull images
|
||||||
|
|
||||||
|
Now that you have DHE configured with a "Domain Name" and have your client
|
||||||
|
Docker daemons configured with the required security settings, you can test your
|
||||||
|
setup by following the instructions for
|
||||||
|
[Using DHE to Push and pull images](./userguide.md#using-dhe-to-push-and-pull-images).
|
||||||
|
|
||||||
|
### DHE web interface and registry authentication
|
||||||
|
|
||||||
|
By default, there is no authentication set on either the DHE web admin
|
||||||
|
interface or the DHE registry. You can restrict access using an in-DHE
|
||||||
|
configured set of users (and passwords), or you can configure DHE to use LDAP-
|
||||||
|
based authentication.
|
||||||
|
|
||||||
|
See [DHE Authentication settings](./configuration.md#authentication) for more
|
||||||
|
details.
|
||||||
|
|
||||||
|
# Upgrading
|
||||||
|
|
||||||
|
DHE has been designed to allow on-the-fly software upgrades. Start by
|
||||||
|
clicking on the "System Health" tab. In the upper, right-hand side of the
|
||||||
|
dashboard, below the navigation bar, you'll see the currently installed version
|
||||||
|
(e.g., `Current Version: 0.1.12345`).
|
||||||
|
|
||||||
|
If your DHE instance is the latest available, you will also see the message:
|
||||||
|
"System Up to Date."
|
||||||
|
|
||||||
|
If there is an upgrade available, you will see the message "System Update
|
||||||
|
Available!" alongside a button labeled "Update to Version X.XX". To upgrade, DHE
|
||||||
|
will pull new DHE container images from the Docker Hub. If you have not already
|
||||||
|
connected to Docker Hub, DHE will prompt you to log in.
|
||||||
|
|
||||||
|
The upgrade process requires a small amount of downtime to complete. To complete
|
||||||
|
the upgrade, DHE will:
|
||||||
|
* Connect to the Docker Hub to pull new container images with the new version of
|
||||||
|
DHE.
|
||||||
|
* Deploy those containers
|
||||||
|
* Shut down the old containers
|
||||||
|
* Resolve any necessary links/urls.
|
||||||
|
|
||||||
|
Assuming you have a decent internet connection, the entire upgrade process
|
||||||
|
should complete within a few minutes.
|
||||||
|
|
||||||
|
## Next Steps
|
||||||
|
|
||||||
|
For information on configuring DHE for your environment, take a look at the
|
||||||
|
[Configuration instructions](./configuration.md).

# Docker Hub Enterprise Quick Start: Basic User Workflow
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
This Quick Start Guide will give you a hands-on look at the basics of using
|
||||||
|
Docker Hub Enterprise (DHE), Docker’s on-premise image storage application.
|
||||||
|
This guide will walk you through using DHE to complete a typical, and critical,
|
||||||
|
part of building a development pipeline: setting up a Jenkins instance. Once you
|
||||||
|
complete the task, you should have a good idea of how DHE works and how it might
|
||||||
|
be useful to you.
|
||||||
|
|
||||||
|
Specifically, this guide demonstrates the process of retrieving the
|
||||||
|
[official Docker image for Jenkins](https://registry.hub.docker.com/_/jenkins/),
|
||||||
|
customizing it to suit your needs, and then hosting it on your private instance
|
||||||
|
of DHE located inside your enterprise’s firewalled environment. Your developers
|
||||||
|
will then be able to retrieve the custom Jenkins image in order to use it to
|
||||||
|
build CI/CD infrastructure for their projects, no matter the platform they’re
|
||||||
|
working from, be it a laptop, a VM, or a cloud provider.
|
||||||
|
|
||||||
|
The guide will walk you through the following steps:
|
||||||
|
|
||||||
|
1. Pulling the official Jenkins image from the public Docker Hub
|
||||||
|
2. Customizing the Jenkins image to suit your needs
|
||||||
|
3. Pushing the customized image to DHE
|
||||||
|
4. Pulling the customized image from DHE
|
||||||
|
4. Launching a container from the custom image
|
||||||
|
5. Using the new Jenkins container
|
||||||
|
|
||||||
|
You should be able to complete this guide in about thirty minutes.
|
||||||
|
|
||||||
|
> **Note:** This guide assumes you have installed a working instance of DHE
|
||||||
|
> reachable at dhe.yourdomain.com. If you need help installing and configuring
|
||||||
|
> DHE, please consult the
|
||||||
|
[installation instructions](./install.md).
|
||||||
|
|
||||||
|
|
||||||
|
## Pulling the official Jenkins image
|
||||||
|
|
||||||
|
> **Note:** This guide assumes you are familiar with basic Docker concepts such
|
||||||
|
> as images, containers, and registries. If you need to learn more about Docker
|
||||||
|
> fundamentals, please consult the
|
||||||
|
> [Docker user guide](http://docs.docker.com/userguide/).
|
||||||
|
|
||||||
|
First, you will retrieve a copy of the official Jenkins image from the Docker Hub. From the CLI of a machine running the Docker Engine on your network, use
|
||||||
|
the
|
||||||
|
[`docker pull`](https://docs.docker.com/reference/commandline/cli/#pull)
|
||||||
|
command to pull the public Jenkins image.
|
||||||
|
|
||||||
|
$ docker pull jenkins
|
||||||
|
|
||||||
|
> **Note:** This guide assumes you can run Docker commands from a machine where
|
||||||
|
> you are a member of the `docker` group, or have root privileges. Otherwise, you may
|
||||||
|
> need to add `sudo` to the example commands below.
|
||||||
|
|
||||||
|
Docker will start the process of pulling the image from the Hub. Once it has completed, the Jenkins image should be visible in the output of a [`docker images`](https://docs.docker.com/reference/commandline/cli/#images) command:
|
||||||
|
|
||||||
|
$ docker images
|
||||||
|
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
|
||||||
|
jenkins latest 1a7cc22b0ee9 6 days ago 662 MB
|
||||||
|
|
||||||
|
> **Note:** Because the `pull` command did not specify any tags, it will pull
|
||||||
|
> the latest version of the public Jenkins image. If your enterprise environment
|
||||||
|
> requires you to use a specific version, add the tag for the version you need
|
||||||
|
> (e.g., `jenkins:1.565`).
|
||||||
|
|
||||||
|
## Customizing the Jenkins image
|
||||||
|
|
||||||
|
Now that you have a local copy of the Jenkins image, you’ll customize it so that
|
||||||
|
the containers it builds will integrate with your infrastructure. To do this,
|
||||||
|
you’ll create a custom Docker image that adds a Jenkins plugin that provides
|
||||||
|
fine grained user management. You’ll also configure Jenkins to be more secure by
|
||||||
|
disabling HTTP access and forcing it to use HTTPS.
|
||||||
|
You’ll do this by using a `Dockerfile` and the `docker build` command.
|
||||||
|
|
||||||
|
> **Note:** These are obviously just a couple of examples of the many ways you
|
||||||
|
> can modify and configure Jenkins. Feel free to add or substitute whatever
|
||||||
|
> customization is necessary to run Jenkins in your environment.
|
||||||
|
|
||||||
|
### Creating a `build` context
|
||||||
|
|
||||||
|
In order to add the new plugin and configure HTTPS access to the custom Jenkins
|
||||||
|
image, you need to:
|
||||||
|
|
||||||
|
1. Create text file that defines the new plugin
|
||||||
|
2. Create copies of the private key and certificate
|
||||||
|
|
||||||
|
All of the above files need to be in the same directory as the Dockerfile you
|
||||||
|
will create in the next step.
|
||||||
|
|
||||||
|
1. Create a build directory called `build`, and change to that new directory:
|
||||||
|
|
||||||
|
$ mkdir build && cd build
|
||||||
|
|
||||||
|
In this directory, create a new file called `plugins` and add the following
|
||||||
|
line:
|
||||||
|
|
||||||
|
role-strategy:2.2.0
|
||||||
|
|
||||||
|
(The plugin version used above was the latest version at the time of writing.)
|
||||||
|
|
||||||
|
2. You will also need to make copies of the server’s private key and certificate. Give the copies the following names — `https.key` and `https.pem`.
|
||||||
|
|
||||||
|
> **Note:** Because creating new keys varies widely by platform and
|
||||||
|
> implementation, this guide won’t cover key generation. We assume you have
|
||||||
|
> access to existing keys. If you don’t have access, or can’t generate keys
|
||||||
|
> yourself, feel free to skip the steps involving them and HTTPS config. The
|
||||||
|
> guide will still walk you through building a custom Jenkins image and pushing
|
||||||
|
> and pulling that image using DHE.
|
||||||
|
|
||||||
|
### Creating a Dockerfile
|
||||||
|
|
||||||
|
In the same directory as the `plugins` file and the private key and certificate,
|
||||||
|
create a new [`Dockerfile`](https://docs.docker.com/reference/builder/) with the
|
||||||
|
following contents:
|
||||||
|
|
||||||
|
FROM jenkins
|
||||||
|
|
||||||
|
#New plugins must be placed in the plugins file
|
||||||
|
COPY plugins /usr/share/jenkins/plugins
|
||||||
|
|
||||||
|
#The plugins.sh script will install new plugins
|
||||||
|
RUN /usr/local/bin/plugins.sh /usr/share/jenkins/plugins
|
||||||
|
|
||||||
|
#Copy private key and cert to image
|
||||||
|
COPY https.pem /var/lib/jenkins/cert
|
||||||
|
COPY https.key /var/lib/jenkins/pk
|
||||||
|
|
||||||
|
#Configure HTTP off and HTTPS on, using port 1973
|
||||||
|
ENV JENKINS_OPTS --httpPort=-1 --httpsPort=1973 --httpsCertificate=/var/lib/jenkins/cert --httpsPrivateKey=/var/lib/jenkins/pk
|
||||||
|
|
||||||
|
The first `COPY` instruction in the above will copy the `plugin` file created
|
||||||
|
earlier into the `/usr/share/jenkins` directory within the custom image you are
|
||||||
|
defining with the `Dockerfile`.
|
||||||
|
|
||||||
|
The `RUN` instruction will execute the `/usr/local/bin/plugins.sh` script with
|
||||||
|
the newly copied `plugins` file, which will install the listed plugin.
|
||||||
|
|
||||||
|
The next two `COPY` instructions copy the server’s private key and certificate
|
||||||
|
into the required directories within the new image.
|
||||||
|
|
||||||
|
The `ENV` instruction creates an environment variable called `JENKINS_OPT` in
|
||||||
|
the image you are about to create. This environment variable will be present in
|
||||||
|
any containers launched form the image and contains the required settings to
|
||||||
|
tell Jenkins to disable HTTP and operate over HTTPS.
|
||||||
|
|
||||||
|
> **Note:** You can specify any valid port number as part of the `JENKINS_OPT`
|
||||||
|
> environment variable declared above. The value `1973` used in the example is
|
||||||
|
> arbitrary.
|
||||||
|
|
||||||
|
The `Dockerfile`, the `plugins` file, as well as the private key and
|
||||||
|
certificate, must all be in the same directory because the `docker build`
|
||||||
|
command uses the directory that contains the `Dockerfile` as its “build
|
||||||
|
context”. Only files contained within that “build context” will be included in
|
||||||
|
the image being built.
|
||||||
|
|
||||||
|
### Building your custom image
|
||||||
|
|
||||||
|
Now that the `Dockerfile`, the `plugins` file, and the files required for HTTPS
|
||||||
|
operation are created in your current working directory, you can build your
|
||||||
|
custom image using the
|
||||||
|
[`docker build` command](https://docs.docker.com/reference/commandline/cli/#build):
|
||||||
|
|
||||||
|
docker build -t dhe.yourdomain.com/ci-infrastructure/jnkns-img .
|
||||||
|
|
||||||
|
> **Note:** Don’t miss the period (`.`) at the end of the command above. This
|
||||||
|
> tells the `docker build` command to use the current working directory as the
|
||||||
|
> "build context".
|
||||||
|
|
||||||
|
This command will build a new Docker image called `jnkns-img` which is based on
|
||||||
|
the public Jenkins image you pulled earlier, but contains all of your
|
||||||
|
customization.
|
||||||
|
|
||||||
|
Please note the use of the `-t` flag in the `docker build` command above. The
|
||||||
|
`-t` flag lets you tag an image so it can be pushed to a custom repository. In
|
||||||
|
the example above, the new image is tagged so it can be pushed to the
|
||||||
|
`ci-infrastructure` Repository within the `dhe.yourdomain.com` registry (your
|
||||||
|
local DHE instance). This will be important when you need to `push` the
|
||||||
|
customized image to DHE later.
|
||||||
|
|
||||||
|
A `docker images` command will now show the custom image alongside the Jenkins
|
||||||
|
image pulled earlier:
|
||||||
|
|
||||||
|
$ sudo docker images
|
||||||
|

|
||||||
|
|
||||||
|
## Pushing to Docker Hub Enterprise
|
||||||
|
|
||||||
|
Now that you’ve create the custom image, it can be pushed to DHE using the
|
||||||
|
[`docker push`command](https://docs.docker.com/reference/commandline/cli/#push):
|
||||||
|
|
||||||
|
$ docker push dhe.yourdomain.com/ci-infrastructure/jnkns-img
|
||||||
|
511136ea3c5a: Image successfully pushed
|
||||||
|

|
||||||
|

|
||||||
|
492ed3875e3e: Image successfully pushed
|
||||||
|
fc0ab3008d40: Image successfully pushed
|
||||||
|
|
||||||
|
You can view the traffic throughput while the custom image is being pushed from
|
||||||
|
the `System Health` tab in DHE:
|
||||||
|
|
||||||
|
![DHE console push throughput](../assets/console-push.png)
|
||||||
|
|
||||||
|
Once the image is successfully pushed, it can be downloaded, or pulled, by any
|
||||||
|
Docker host that has access to DHE.
|
||||||
|
|
||||||
|
## Pulling from Docker Hub Enterprise
|
||||||
|
To pull the `jnkns-img` image from DHE, run the
|
||||||
|
[`docker pull`](https://docs.docker.com/reference/commandline/cli/#pull)
|
||||||
|
command from any Docker Host that has access to your DHE instance:
|
||||||
|
|
||||||
|
$ docker pull dhe.yourdomain.com/ci-infrastructure/jnkns-img
|
||||||
|
latest: Pulling from dhe.yourdomain.com/ci-infrastructure/jnkns-img

|
||||||
|
|

## Launching a custom Jenkins container
|
||||||
|
|
||||||
|
Now that you’ve successfully pulled the customized Jenkins image from DHE, you
|
||||||
|
can create a container from it with the
|
||||||
|
[`docker run` command](https://docs.docker.com/reference/commandline/cli/#run):
|
||||||
|
|
||||||
|
|
||||||
|
$ docker run -p 1973:1973 --name jenkins01 dhe.yourdomain.com/ci-infrastructure/jnkns-img
|
||||||
|
/usr/share/jenkins/ref/init.groovy.d/tcp-slave-angent-port.groovy
|
||||||
|
/usr/share/jenkins/ref/init.groovy.d/tcp-slave-angent-port.groovy -> init.groovy.d/tcp-slave-angent-port.groovy
|
||||||
|
copy init.groovy.d/tcp-slave-angent-port.groovy to JENKINS_HOME
|
||||||
|
/usr/share/jenkins/ref/plugins/role-strategy.hpi
|
||||||
|
/usr/share/jenkins/ref/plugins/role-strategy.hpi -> plugins/role-strategy.hpi
|
||||||
|
copy plugins/role-strategy.hpi to JENKINS_HOME
|
||||||
|
/usr/share/jenkins/ref/plugins/dockerhub.hpi
|
||||||
|
/usr/share/jenkins/ref/plugins/dockerhub.hpi -> plugins/dockerhub.hpi
|
||||||
|
copy plugins/dockerhub.hpi to JENKINS_HOME
|
||||||
|

|
||||||
|
|
||||||
|
You can view the newly launched a container, called `jenkins01`, using the
|
||||||
|
[`docker ps` command](https://docs.docker.com/reference/commandline/cli/#ps):
|
||||||
|
|
||||||
|
$ docker ps

|
## Accessing the new Jenkins container
|
||||||
|
|
||||||
|
The previous `docker run` command mapped port `1973` on the container to port
|
||||||
|
`1973` on the Docker host, so the Jenkins Web UI can be accessed at
|
||||||
|
`https://<docker-host>:1973` (Don’t forget the `s` at the end of `https`.)
|
||||||
|
|
||||||
|
> **Note:** If you are using a self-signed certificate, you may get a security
|
||||||
|
> warning from your browser telling you that the certificate is self-signed and
|
||||||
|
> not trusted. You may wish to add the certificate to the trusted store in order
|
||||||
|
> to prevent further warnings in the future.
|
||||||
|
|
||||||
|
![Jenkins landing page](../assets/jenkins-ui.png)
|
||||||
|
|
||||||
|
From within the Jenkins Web UI, navigate to `Manage Jenkins` (on the left-hand
|
||||||
|
pane) > `Manage Plugins` > `Installed`. The `Role-based Authorization Strategy`
|
||||||
|
plugin should be present with the `Uninstall` button available to the right.
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
In another browser session, try to access Jenkins via the default HTTP port 8080
|
||||||
|
— `http://<docker-host>:8080`. This should result in a “connection timeout,”
|
||||||
|
showing that Jenkins is not available on its default port 8080 over HTTP.
|
||||||
|
|
||||||
|
This demonstration shows your Jenkins image has been configured correctly for
|
||||||
|
HTTPS access, your new plugin was added and is ready for use, and HTTP access
|
||||||
|
has been disabled. At this point, any member of your team can use `docker pull`
|
||||||
|
to access the image from your DHE instance, allowing them to access a
|
||||||
|
configured, secured Jenkins instance that can run on any infrastructure.
|
||||||
|
|
||||||
|
## Next Steps
|
||||||

# Docker Hub Enterprise User's Guide
|
||||||
|
|
||||||
|
This guide covers tasks and functions a user of Docker Hub Enterprise (DHE) will
|
||||||
|
need to know about, such as pushing or pulling images, etc. For tasks DHE
|
||||||
|
administrators need to accomplish, such as configuring or monitoring DHE, please
|
||||||
|
visit the [Administrator's Guide](./adminguide.md).
|
||||||
|
|
||||||
|
## Using DHE to push and pull images
|
||||||
|
|
||||||
|
The primary use case for DHE users is to push and pull images to and from the
|
||||||
|
DHE image storage service. The following instructions describe these procedures.
|
||||||
|
|
||||||
|
> **Note**: If your DHE instance has authentication enabled, you will need to
|
||||||
|
>use your command line to `docker login <dhe-hostname>` (e.g., `docker login
|
||||||
|
> dhe.yourdomain.com`).
|
||||||
|
>
|
||||||
|
> Failures due to unauthenticated `docker push` and `docker pull` commands will
|
||||||
|
> look like :
|
||||||
|
>
|
||||||
|
> $ docker pull dhe.yourdomain.com/hello-world
|
||||||
|
> Pulling repository dhe.yourdomain.com/hello-world
|
||||||
|
> FATA[0001] Error: image hello-world:latest not found
|
||||||
|
>
|
||||||
|
> $ docker push dhe.yourdomain.com/hello-world
|
||||||
|
> The push refers to a repository [dhe.yourdomain.com/hello-world] (len: 1)
|
||||||
|
> e45a5af57b00: Image push failed
|
||||||
|
> FATA[0001] Error pushing to registry: token auth attempt for registry https://dhe.yourdomain.com/v2/: https://> dhe.yourdomain.com/auth/v2/token/?scope=repository%3Ahello-world%3Apull%2Cpush&service=dhe.yourdomain.com > request failed with status: 401 Unauthorized
|
||||||
|
|
||||||
|
|
||||||
|
1. Pull the `hello-world` official image from the Docker Hub. By default, if
|
||||||
|
Docker can't find an image locally, it will attempt to pull the image from the
|
||||||
|
Docker Hub.
|
||||||
|
|
||||||
|
`$ docker pull hello-world`
|
||||||
|
|
||||||
|
2. List your available images.
|
||||||
|
|
||||||
|
$ docker images
|
||||||
|
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
|
||||||
|
hello-world latest e45a5af57b00 3 months ago 910 B
|
||||||
|
|
||||||
|
Your list should include the `hello-world` image from the earlier run.
|
||||||
|
|
||||||
|
3. Re-tag the `hello-world` image so that it refers to your DHE server.
|
||||||
|
|
||||||
|
`$ docker tag hello-world:latest dhe.yourdomain.com/demouser/hello-mine:latest`
|
||||||
|
|
||||||
|
The command labels a `hello-world:latest` image using a new tag in the
|
||||||
|
`[REGISTRYHOST/][USERNAME/]NAME[:TAG]` format. The `REGISTRYHOST` in this
|
||||||
|
case is the DHE server, `dhe.yourdomain.com`, and the `USERNAME` is
|
||||||
|
`demouser`.
|
||||||
|
|
||||||
|
4. List your new image.
|
||||||
|
|
||||||
|
$ docker images
|
||||||
|
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
|
||||||
|
hello-world latest e45a5af57b00 3 months ago 910 B
|
||||||
|
dhe.yourdomain.com/demouser/hello-mine latest e45a5af57b00 3 months ago 910 B
|
||||||
|
|
||||||
|
You should see your new image label in the listing, with the same `IMAGE ID`
|
||||||
|
as the Official image.
|
||||||
|
|
||||||
|
5. Push this new image to your DHE server.
|
||||||
|
|
||||||
|
`$ docker push dhe.yourdomain.com/demouser/hello-mine:latest`
|
||||||
|
|
||||||
|
6. Set up a test of DHE by removing all images from your local environment:
|
||||||
|
|
||||||
|
`$ docker rmi -f $(docker images -q -a)`
|
||||||
|
|
||||||
|
This command is for illustrative purposes only: removing the image forces
|
||||||
|
any subsequent `run` to pull from a remote registry (such as DHE) rather
|
||||||
|
than from a local cache. If you run `docker images` after this you should
|
||||||
|
not see any instance of `hello-world` or `hello-mine` in your images list.
|
||||||
|
|
||||||
|
$ docker images
|
||||||
|
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
|
||||||
|
|
||||||
|
7. Try running `hello-mine`.
|
||||||
|
|
||||||
|
$ docker run hello-mine
|
||||||
|
Unable to find image 'hello-mine:latest' locally
|
||||||
|
Pulling repository hello-mine
|
||||||
|
FATA[0007] Error: image library/hello-mine:latest not found
|
||||||
|
|
||||||
|
The `run` command fails because your new image doesn't exist on the Docker Hub.
|
||||||
|
|
||||||
|
8. Run `hello-mine` again, this time pointing it to pull from DHE:
|
||||||
|
|
||||||
|
$ docker run dhe.yourdomain.com/demouser/hello-mine
|
||||||
|
latest: Pulling from dhe.yourdomain.com/demouser/hello-mine
|
||||||
|
511136ea3c5a: Pull complete
|
||||||
|
31cbccb51277: Pull complete
|
||||||
|
e45a5af57b00: Already exists
|
||||||
|
Digest: sha256:45f0de377f861694517a1440c74aa32eecc3295ea803261d62f950b1b757bed1
|
||||||
|
Status: Downloaded newer image for dhe.yourdomain.com/demouser/hello-mine:latest
|
||||||
|
|
||||||
|
If you run `docker images` after this you'll see a `hello-mine` image.
|
||||||
|
|
||||||
|
$ docker images
|
||||||
|
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
|
||||||
|
dhe.yourdomain.com/demouser/hello-mine latest e45a5af57b00 3 months ago 910 B
|
||||||
|
|
||||||
|
> **Note**: If the Docker daemon on which you are running `docker push` doesn't
|
||||||
|
> have the right certificates set up, you will get an error similar to:
|
||||||
|
>
|
||||||
|
> $ docker push dhe.yourdomain.com/demouser/hello-world
|
||||||
|
> FATA[0000] Error response from daemon: v1 ping attempt failed with error: Get https://dhe.yourdomain.com/v1/_ping: x509: certificate signed by unknown authority. If this private registry supports only HTTP or HTTPS with an unknown CA certificate, please add `--insecure-registry dhe.yourdomain.com` to the daemon's arguments. In the case of HTTPS, if you have access to the registry's CA certificate, no need for the flag; simply place the CA certificate at /etc/docker/certs.d/dhe.yourdomain.com/ca.crt
|
||||||
|
|
||||||
|
9. You have now successfully created a custom image, `hello-mine`, tagged it,
|
||||||
|
and pushed it to the image storage provided by your DHE instance. You then
|
||||||
|
pulled that image back down from DHE and onto your machine, where you can
|
||||||
|
use it to create a container containing the "Hello World" application..
|
||||||
|
|
||||||
|
## Next Steps
|
||||||
|
|
||||||
|
For information on administering DHE, take a look at the [Administrator's Guide](./adminguide.md).

<!--TODO:
|
||||||
|
|
||||||
|
* mention that image aliases that are not in the same repository are not updated - either on push or pull
|
||||||
|
* but that multiple tags in one repo are pushed if you don't specify the `:tag` (ie, `imagename` does not always mean `imagename:latest`)
|
||||||
|
* show what happens for non-latest, and when there are more than one tag in a repo
|
||||||
|
* explain the fully-qualified repo/image name -->
