From the -f description: (HTTP) Fail silently (no output at all) on server errors. This is mostly done to better enable scripts etc to better deal with failed attempts. In normal cases when an HTTP server fails to deliver a document, it returns an HTML document stating so (which often also describes why and more). This flag will prevent curl from outputting that and return error 22. Signed-off-by: Sebastiaan van Stijn <github@gone.nl>

# Dockerizing a Riak service
|
|
|
|
The goal of this example is to show you how to build a Docker image with
|
|
Riak pre-installed.
|
|
|
|
## Creating a Dockerfile
|
|
|
|
Create an empty file called `Dockerfile`:
|
|
|
|
$ touch Dockerfile
|
|
|
|
Next, define the parent image you want to use to build your image on top
|
|
of. We'll use [Ubuntu](https://registry.hub.docker.com/_/ubuntu/) (tag:
|
|
`trusty`), which is available on [Docker Hub](https://hub.docker.com):
|
|
|
|
# Riak
|
|
#
|
|
# VERSION 0.1.1
|
|
|
|
# Use the Ubuntu base image provided by dotCloud
|
|
FROM ubuntu:trusty
|

|
|
|
|
After that, we install the curl which is used to download the repository setup
|
|
script and we download the setup script and run it.
|
|
|
|
# Install Riak repository before we do apt-get update, so that update happens
|
|
# in a single step
|
|
RUN apt-get install -q -y curl && \
|
|
curl -fsSL https://packagecloud.io/install/repositories/basho/riak/script.deb | sudo bash
|
|
|
|
Then we install and setup a few dependencies:
|
|
|
|
- `supervisor` is used manage the Riak processes
|
|
- `riak=2.0.5-1` is the Riak package coded to version 2.0.5
|
|
|
|
<!-- -->
|
|
|
|
# Install and setup project dependencies
|
|
RUN apt-get update && \
|
|
apt-get install -y supervisor riak=2.0.5-1
|
|
|
|
RUN mkdir -p /var/log/supervisor
|
|
|
|
RUN locale-gen en_US en_US.UTF-8
|
|
|
|
COPY supervisord.conf /etc/supervisor/conf.d/supervisord.conf
|
|
|
|
After that, we modify Riak's configuration:
|
|
|
|
# Configure Riak to accept connections from any host
|
|
RUN sed -i "s|listener.http.internal = 127.0.0.1:8098|listener.http.internal = 0.0.0.0:8098|" /etc/riak/riak.conf
|
|
RUN sed -i "s|listener.protobuf.internal = 127.0.0.1:8087|listener.protobuf.internal = 0.0.0.0:8087|" /etc/riak/riak.conf
|
|
|
|
Then, we expose the Riak Protocol Buffers and HTTP interfaces:
|
|
|
|
# Expose Riak Protocol Buffers and HTTP interfaces
|
|
EXPOSE 8087 8098
|
|
|
|
Finally, run `supervisord` so that Riak is started:
|
|
|
|
CMD ["/usr/bin/supervisord"]
|
|
|
|
## Create a supervisord configuration file
|
|
|
|
Create an empty file called `supervisord.conf`. Make
|
|
sure it's at the same directory level as your `Dockerfile`:
|
|
|
|
touch supervisord.conf
|
|
|
|
Populate it with the following program definitions:
|
|
|
|
[supervisord]
|
|
nodaemon=true
|
|
|
|
[program:riak]
|
|
command=bash -c "/usr/sbin/riak console"
|
|
numprocs=1
|
|
autostart=true
|
|
autorestart=true
|
|
user=riak
|
|
environment=HOME="/var/lib/riak"
|
|
stdout_logfile=/var/log/supervisor/%(program_name)s.log
|
|
stderr_logfile=/var/log/supervisor/%(program_name)s.log
|
|
|
|
## Build the Docker image for Riak
|
|
|
|
Now you should be able to build a Docker image for Riak:
|
|
|
|
$ docker build -t "<yourname>/riak" .
|
|
|
|
## Next steps
|
|
|
|
Riak is a distributed database. Many production deployments consist of
|
|
[at least five nodes](
|
|
http://basho.com/why-your-riak-cluster-should-have-at-least-five-nodes/).
|
|
See the [docker-riak](https://github.com/hectcastro/docker-riak) project
|
|
details on how to deploy a Riak cluster using Docker and Pipework.
