# Ansible Role: Docker
|
|
|
|
[](https://travis-ci.org/geerlingguy/ansible-role-docker)
|
|
|
|
An Ansible Role that installs [Docker](https://www.docker.com) on Linux.
|
|
|
|
## Requirements
|
|
|
|
None.
|
|
|
|
## Role Variables
|
|
|
|
Available variables are listed below, along with default values (see `defaults/main.yml`):
|
|
|
|
# Edition can be one of: 'ce' (Community Edition) or 'ee' (Enterprise Edition).
|
|
docker_edition: 'ce'
|
|
docker_package: "docker-{{ docker_edition }}"
|
|
docker_package_state: present
|
|
|
|
The `docker_edition` should be either `ce` (Community Edition) or `ee` (Enterprise Edition). You can also specify a specific version of Docker to install using the distribution-specific format: Red Hat/CentOS: `docker-{{ docker_edition }}-<VERSION>`; Debian/Ubuntu: `docker-{{ docker_edition }}=<VERSION>`.
|
|
|
|
You can control whether the package is installed, uninstalled, or at the latest version by setting `docker_package_state` to `present`, `absent`, or `latest`, respectively. Note that the Docker daemon will be automatically restarted if the Docker package is updated. This is a side effect of flushing all handlers (running any of the handlers that have been notified by this and any other role up to this point in the play).
|
|
|
|
docker_service_state: started
|
|
docker_service_enabled: true
|
|
docker_restart_handler_state: restarted
|
|
|
|
Variables to control the state of the `docker` service, and whether it should start on boot. If you're installing Docker inside a Docker container without systemd or sysvinit, you should set these to `stopped` and set the enabled variable to `no`.
|
|
|
|
docker_install_compose: true
|
|
docker_compose_version: "1.22.0"
|
|
docker_compose_path: /usr/local/bin/docker-compose
|
|
|
|
Docker Compose installation options.
|
|
|
|
docker_apt_release_channel: stable
|
|
docker_apt_arch: amd64
|
|
docker_apt_repository: "deb [arch={{ docker_apt_arch }}] https://download.docker.com/linux/{{ ansible_distribution|lower }} {{ ansible_distribution_release }} {{ docker_apt_release_channel }}"
|
|
docker_apt_ignore_key_error: True
|
|
|
|
(Used only for Debian/Ubuntu.) You can switch the channel to `edge` if you want to use the Edge release.
|
|
|
|
docker_yum_repo_url: https://download.docker.com/linux/centos/docker-{{ docker_edition }}.repo
|
|
docker_yum_repo_enable_edge: '0'
|
|
docker_yum_repo_enable_test: '0'
|
|
|
|
(Used only for RedHat/CentOS.) You can enable the Edge or Test repo by setting the respective vars to `1`.
|
|
|
|
docker_users:
|
|
- user1
|
|
- user2
|
|
|
|
A list of system users to be added to the `docker` group (so they can use Docker on the server).
|
|
|
|
## Use with Ansible (and `docker` Python library)
|
|
|
|
Many users of this role wish to also use Ansible to then _build_ Docker images and manage Docker containers on the server where Docker is installed. In this case, you can easily add in the `docker` Python library using the `geerlingguy.pip` role:
|
|
|
|
```yaml
|
|
- hosts: all
|
|
|
|
vars:
|
|
pip_install_packages:
|
|
- name: docker
|
|
|
|
roles:
|
|
- geerlingguy.pip
|
|
- geerlingguy.docker
|
|
```
|
|
|
|
## Dependencies
|
|
|
|
None.
|
|
|
|
## Example Playbook
|
|
|
|
```yaml
|
|
- hosts: all
|
|
roles:
|
|
- geerlingguy.docker
|
|
```
