Charm for Docker

This charm deploys the Docker engine within Juju. 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.

Most people will want to extend this charm to make their Docker container or application deployable from Juju. The Charm layer can be extended to include docker container along with additional operational code. Please refer to the Charm Layers documentation on jujucharms.com for more information.

States

The following states are set by this layer:

  • nvidia-docker.supported

    This state is set when supported GPU hardware is detected.

  • nvidia-docker.installed

    This state is set once CUDA-related packages are installed and configured.

Using the Docker Charm

Docker does not require anything by default so you can deploy the Charm by the following command.

juju deploy docker

NOTE: You can ask Juju to deploy a different release of Ubuntu by using the --series and the code name of the release "trusty" for 14.04 and "xenial" for 16.04.

Once deployed you have a docker-engine running on a unit in Juju. You can open a session to that unit and issue the docker command to start using it right away.

juju ssh docker/0
...
$ docker run hello-world

Scale out Usage

Scaling out the Charm is as simple as adding additional docker units with Juju add-unit command to expand your cluster. However, you will need an SDN solution to provide cross host networking. See the Known Limitations and issues about this.

Configuration

See config.yaml for list of configuration options.

Docker Compose

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.

Contact Information

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.

Charm for Docker
This charm deploys the Docker engine within Juju. 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.
Most people will want to extend this charm to make their Docker container or
application deployable from Juju. The
Charm layer can be extended to
include docker container along with additional operational code. Please refer
to the Charm Layers
documentation on jujucharms.com for more
information.
States
The following states are set by this layer:
  • nvidia-docker.supported
    This state is set when supported GPU hardware is detected.
  • nvidia-docker.installed
    This state is set once CUDA-related packages are installed and configured.
Using the Docker Charm
Docker does not require anything by default so you can deploy the Charm by the
following command.
juju deploy docker

NOTE: You can ask Juju to deploy a different release of Ubuntu by using the
--series and the code name of the release "trusty" for 14.04 and "xenial" for
16.04.
Once deployed you have a docker-engine running on a unit in Juju. You can open
a session to that unit and issue the docker command to start using it
right away.
juju ssh docker/0
...
$ docker run hello-world

Scale out Usage
Scaling out the Charm is as simple as adding additional docker units
with Juju add-unit command to expand your cluster. However, you will need an
SDN solution to provide cross host networking. See the Known Limitations and
issues about this.
Configuration
See config.yaml for
list of configuration options.
Docker Compose
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.
Contact Information
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.
