# Installing Docker on Mac OS X
|
|
|
|
> **Note**:
|
|
> Docker is still under heavy development! We don't recommend using it in
|
|
> production yet, but we're getting closer with each release. Please see
|
|
> our blog post, [Getting to Docker 1.0](
|
|
> http://blog.docker.io/2013/08/getting-to-docker-1-0/)
|
|
|
|
> **Note:**
|
|
> Docker is supported on Mac OS X 10.6 "Snow Leopard" or newer.
|
|
|
|
The Docker Engine uses Linux-specific kernel features, so we run it on OS X
|
|
using a lightweight virtual machine. You can use the OS X Docker client to
|
|
control the virtualized engine to build, run and manage Docker containers.
|
|
|
|
To make this process easier we designed a helper application called
|
|
[boot2docker](https://github.com/boot2docker/boot2docker) to install the
|
|
virtual machine and run the Docker daemon.
|
|
|
|
## Installation
|
|
|
|
1. Download the latest release of the [Docker for OSX Installer](
|
|
https://github.com/boot2docker/osx-installer/releases)
|
|
2. Run the installer, which will install VirtualBox and the Boot2Docker management
|
|
tool.
|
|
|
|
3. Open a terminal and run:
|
|
|
|
```
|
|
boot2docker init
|
|
boot2docker start
|
|
export DOCKER_HOST=tcp://localhost:2375
|
|
```
|
|
|
|
`boot2docker init` will ask you to enter an ssh key passphrase - the simplest
|
|
(but least secure) is to just hit [Enter]. This passphrase is used by the
|
|
`boot2docker ssh` command.
|
|
|
|
Once you have an initialized virtual machine, you can `boot2docker stop`
|
|
and `boot2docker start` it.
|
|
|
|
## Upgrading
|
|
|
|
To upgrade:
|
|
|
|
1. Download the latest release of the [Docker for OSX Installer](
|
|
https://github.com/boot2docker/osx-installer/releases)
|
|
2. Run the installer, which will update VirtualBox and the Boot2Docker management
|
|
tool.
|
|
3. To upgrade your existing virtual machine, open a terminal and run:
|
|
|
|
```
|
|
boot2docker stop
|
|
boot2docker download
|
|
boot2docker start
|
|
```
|
|
|
|
## Running Docker
|
|
|
|
From your terminal, you can try the “hello world” example. Run:
|
|
|
|
$ docker run ubuntu echo hello world
|
|
|
|
This will download the `ubuntu` image and print `hello world`.
|
|
|
|
## Container port redirection
|
|
|
|
The latest version of `boot2docker` sets up two network adapters: one using NAT
|
|
to allow the VM to download images and files from the Internet, and one host only
|
|
network adapter to which the container's ports will be exposed on.
|
|
|
|
If you run a container with an exposed port:
|
|
|
|
```
|
|
docker run --rm -i -t -p 80:80 apache
|
|
```
|
|
|
|
Then you should be able to access that Apache server using the IP address reported
|
|
to you using:
|
|
|
|
```
|
|
boot2docker ssh ip addr show dev eth1
|
|
```
|
|
|
|
Typically, it is 192.168.59.103, but at this point it can change.
|
|
|
|
If you want to share container ports with other computers on your LAN, you will
|
|
need to set up [NAT adaptor based port forwarding](
|
|

|
|
|
|
# Further details
|
|
|
|
The Boot2Docker management tool provides some commands:
|
|
|
|
```
|
|
$ ./boot2docker
|
|
Usage: ./boot2docker [<options>]
|
|
{help|init|up|ssh|save|down|poweroff|reset|restart|config|status|info|delete|download|version}
|
|
[<args>]
|
|
```
|
|
|
|
