Ansible Docker role for EL 6/7

This role installs the latest version of Docker from the official Docker repositories. All the other roles I've found seemed to be way more opinionated. This one just installs docker-ce, starts the service, then leaves you alone. Good day sir.

CentOS 6 Support

The master branch uses Docker CE and thus only supports CentOS 7. For CentOS 6 support, use the centos6 branch:

$ ansible-galaxy install git+https://github.com/DavidWittman/ansible-docker.git,centos6 -p /path/to/roles/dir

Updates will be made to this branch for maintenance only and support for CentOS 6 will be fully deprecated in the future.

Role Variables

• docker_opts - Arguments passed to the docker daemon at start time
• docker_env - Dictionary of environment variables to set for the docker daemon
• docker_engine_cleanup - Set this variable to true to clean up the old docker-engine repositories and packages.

Common Settings

Using an HTTP(S) proxy with Docker

Use the docker_env variable to set the HTTP_PROXY and/or HTTPS_PROXY environment variables:

- hosts: all
  roles:
    - role: DavidWittman.docker
      docker_env:
        HTTP_PROXY: "http://127.0.0.1:8080"
        HTTPS_PROXY: "https://127.0.0.1:8080"
