+# Ansible Role: Docker
+
+[![CI](https://github.com/geerlingguy/ansible-role-docker/workflows/CI/badge.svg?event=push)](https://github.com/geerlingguy/ansible-role-docker/actions?query=workflow%3ACI)
+
+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: "1.26.0"
+    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
+    docker_apt_gpg_key: https://download.docker.com/linux/{{ ansible_distribution | lower }}/gpg
+
+(Used only for Debian/Ubuntu.) You can switch the channel to `nightly` if you want to use the Nightly release.
+
+You can change `docker_apt_gpg_key` to a different url if you are behind a firewall or provide a trustworthy mirror.
+Usually in combination with changing `docker_apt_repository` as well.
+
+    docker_yum_repo_url: https://download.docker.com/linux/centos/docker-{{ docker_edition }}.repo
+    docker_yum_repo_enable_nightly: '0'
+    docker_yum_repo_enable_test: '0'
+    docker_yum_gpg_key: https://download.docker.com/linux/centos/gpg
+
+(Used only for RedHat/CentOS.) You can enable the Nightly or Test repo by setting the respective vars to `1`.
+
+You can change `docker_yum_gpg_key` to a different url if you are behind a firewall or provide a trustworthy mirror.
+Usually in combination with changing `docker_yum_repository` as well.
+
+    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
+```
+
+## License

+MIT / BSD

+## Author Information
+
+This role was created in 2017 by [Jeff Geerling](https://www.jeffgeerling.com/), author of [Ansible for DevOps](https://www.ansiblefordevops.com/).
