An Ansible role installing Docker Engine and Docker Compose on Linux (Debian/Ubuntu).

Requirements

Role Variables

Docker Daemon Configuration

The Docker daemon configuration file (/etc/docker/daemon.json) content may be set explicitly with docker_config variable:

docker_config:
  userns-remap: default
  insecure-registries:
    - registry.example.com:5000

The default configuration file content is following:

{
    "log-driver": "json-file",
    "log-opts": {
        "max-size": "10m",
        "max-file": "3"
    }
}

community.docker Modules Dependencies

Dependencies of community.docker modules are installed by default. Set docker_ansible_dependencies_install to no to disable installation.

Checking of Iptables Rules Managed by Docker

The role checks iptables rules added by Docker. If they are absent Docker daemon is restarted. To disable this behaviour set docker_iptables_check variable to no.

Dependencies

None.
