docker

Installs docker-ce and docker-compose. This role manages daemon configuration as well via /etc/docker/daemon.json. I think it is a bit more convinient configuring the docker daemon with its configuration file instead of passing flags via environments.

Requirements

none so far.

Role Variables

Variable	Type	Default	Description
`docker_daemon_options`	dict	`{group: docker, log-driver: journald}`	Dictionary containing all settings for daemon.json
`docker_packages`	list	`[docker-ce, docker-ce-cli, containerd.io, docker-compose]`	List containing packages which should be installed
`docker_os_skip_list`	list	`[CoreOS, Coreos]`	List of operatingsystems that don't require package installation
`docker_compose_service`	bool	`false`	If set to `true` a systemd service template for docker-compose files is created

There are a bunch of Variables which values depends on os:

docker_repo_url
docker_key_id
docker_key_url
docker_pre_packages

docker_compose_service

When enabled you can store docker-compose files in /etc/docker/compose/ directory.
For example: If you whish to start your example deployment, store it like this: /etc/docker/compose/example.yml
And start it like this: systemctl start docker-compose@example
You can update your deployment with this hack: systemctl start docker-compose@example

Dependencies

none so far.

Example Playbook

basic example:

---
- hosts: servers
  roles:
     - derJD.docker

how config for my workstation would look like:

---
- hosts: workstation
  vars:
    docker_daemon_options:
      group: docker
      bip: 10.53.0.1/27
      log-driver: journald
      storage-driver: zfs
  roles:
     - derJD.docker
