Docker image updater
====================
*A utility to update docker images automatically. Supports execution of
arbitrary commands when an image is updated, in order to restart running
containers or trigger other custom behaviour.*
.. image:: https://travis-ci.org/zoni/docker-image-updater.svg?branch=master
:target: https://travis-ci.org/zoni/docker-image-updater
.. image:: https://coveralls.io/repos/zoni/docker-image-updater/badge.svg?branch=master
:target: https://coveralls.io/r/zoni/docker-image-updater
Installation
------------
Docker image updater can be installed from the
`Python Package Index <https://pypi.python.org/pypi/docker-image-updater>`_
using::
pip install docker-image-updater
Installation into a `virtualenv <https://virtualenv.pypa.io/en/latest/>`_
is highly recommended!
Usage
-----
::
usage: docker-image-updater [-h] [-f FILE] [--debug] [file [file ...]]
positional arguments:
file configuration file(s) to use
optional arguments:
-h, --help show this help message and exit
-f FILE, --file FILE deprecated - this flag will be removed in the future
--debug show debug messages
Docker image updater requires one or more configuration files which specify
sets of images to watch and commands to execute. By default it will look
for `/etc/docker-image-updater.yml` but you may give one or more alternate
files on the command-line.
When specifying more than one configuration file, the settings will be
merged together with items from the latter configuration file(s) overwriting
items from earlier files.
Recommended usage is to run docker image updater from cron, using
something like `cronic <http://habilis.net/cronic/>`_ to receive mail
only in case of errors.
Example output
--------------
::
# docker-image-updater
22:13:04 INFO Updater Checking images in set jenkins
22:13:04 INFO Updater Updating image zoni/jenkins
22:13:04 INFO Updater Pulling image zoni/jenkins
...........................................................................................................................................................................................................................................................................................................................
22:14:50 INFO Updater Image zoni/jenkins updated to latest version
22:14:50 INFO Updater Running command: supervisorctl restart jenkins
jenkins: stopped
jenkins: started
22:14:54 INFO Updater Command exited successfully
Configuration format
--------------------
Configuration is expressed through a YAML file such as the following:
::
config:
docker:
base_url: "unix://var/run/docker.sock"
version: "1.16"
watch:
my-app:
images:
- my-app
- redis
commands:
- restart my-app
The item `watch` defines sets of images to watch. This is a dictionary where
the keys (`my-app` in the example above) are arbitrary values for human
reference. Under each of these keys a dictonary with the items `images` and
`commands` is expected.
`images` defines a list of docker images to check for updates. You can
specify these as `image:tag` or simply as `image`, in which case Docker will
use the *latest* tag automatically.
`commands` defines a list of shell commands to execute whenever one of the
listed images was updated. These will be run sequentially, in order.
All items under `config.docker` are passed to the Docker client.
For supported options, refer to the
`docker-py documentation <http://docker-py.readthedocs.org/en/latest/api/>`_.
Exit codes
----------
Docker image updater will exit with status 0 when everything went well,
and there were either no updates or images were updated and all defined
commands returned status code 0.
If an image fails to update or one or more defined commands exits with
a non-zero exit status then docker image updater will itself exit with
status 1.
