docker-sync
Helper utility for configuration management tools like Chef and Puppet.
Given a directory of config files (see the example
directory), docker-sync
will ensure that the running containers are kept in sync with the config files,
and will remove containers that no longer have a related config file.
It's a little bit opinionated: container links aren't supported (tho they could
be in the future); all containers are detached. The image a container is
instantiated from is compared to its tag in its appropriate registry, and the
pull is only done if the registry tag is different than the local tag (a docker
pull
is slow even when there are no changes).
In the future I may support dogestry as an alternative (or companion to) a traditional Docker registry.
installation
pip install docker-sync
Or from a clone:
pip install -r requirements.txt
pip install .
example usage
docker-sync ./example
or
./docker_sync/cli.py ./example
options
You can add --no-pull
to skip pulling images; very useful when you're
iterating on your configs.
