This subordinate charm deploys the Docker engine within a running Juju charm application. Docker is an open platform for developers and sysadmins to build, ship, and run distributed applications in containers.
Docker containers wrap a piece of software in a complete file system that contains everything needed to run an application on a server.
Docker focuses on distributing applications as containers that can be quickly assembled from components that are run the same on different servers without environmental dependencies. This eliminates the friction between development, QA, and production environments.
The following states are set by this subordinate:
-
endpoint.{relation name}.availableThis state is set when docker is available for use.
The Docker subordinate charm is to be used with principal charms that need a container runtime. To use, we deploy the Docker subordinate charm and then relate it to the principal charm.
juju deploy cs:~containers/docker
juju add-relation docker [principal charm]
This charm will automatically scale out with the principal charm.
See config.yaml for list of configuration options.
Note: Setting HTTP proxy values will override
juju-http-proxyorjuju-https-proxyon the model.
This charm also installs the 'docker-compose' python package using pip. So once the charm has finished installing you have the ability to use Docker Compose functionality such as control files, and logging.
This charm is available at https://jujucharms.com/docker and contains the open source operations code to deploy on all public clouds in the Juju ecosystem.
