+## What is ansible-docker?
+It is an [Ansible](http://www.ansible.com/home) role to:
+
+- Install Docker (editions, channels and version pinning are all supported)
+- Install Docker Compose
+- Manage login credentials for 1 or more public or private Docker registries
+- Set up 1 or more users to run Docker without needing root access
+- Configure a cron job to run Docker clean up commands
+- Configure the Docker daemon's options and environment variables
+
+## Why would you want to use this role?
+If you're like me, you probably love Docker. This role provides everything you
+need to get going with a production ready Docker host.
+
+## Supported platforms
+
+- Ubuntu 16.04 LTS (Xenial)
+- Ubuntu 18.04 LTS (Bionic)
+- Debian 8 (Jessie)
+- Debian 9 (Stretch)
+
+## Role variables
+```
+# When set to "True", the Docker package and supporting files will be removed.
+docker_remove_package: False
+
+# Do you want to use "ce" (community edition) or "ee" (enterprise edition)?
+docker_edition: "ce"
+
+# Do you want to use the "stable", "edge", "testing" or "nightly" channels?
+# Add more than 1 channel by separating each one by a space.
+docker_channel: "stable"
+
+# When set to "latest" this role will always attempt to install the latest
+# version based on the channel you selected. This could lead to something like
+# Docker 18.06 being installed today but then a year from now, re-running the
+# role will result in 19.06 or whatever Docker happens to use a year from now.
+#
+# If you want to pin a version simply put "18.06", "18.06.1" or whatever version
+# you want. Even if you update your package list and newer Docker versions are
+# available this role will stick to the pinned version on all future runs.
+docker_version: "latest"
+
+# Do you want to also install Docker Compose?
+docker_install_docker_compose: True
+
+# If Docker Compose is being installed, which version do you want to use?
+docker_compose_version: "1.22.0"
+
+# A list of users to be added to the docker group. For example if you have a
+# user of "admin", then you'll want to set docker_users: ["admin"] here.
+#
+# Keep in mind this user needs to already exist, this role will not create it.
+#
+# This role does not configure User Namespaces or any other security features
+# by default. If the user you add here has SSH access to your server then you're
+# effectively giving them root access to the system since they can run docker
+# without sudo and volume mount in any file on your file system.
+#
+# In a controlled environment this is safe, but like anything security related
+# it's worth knowing this up front. You can enable User Namespaces and any
+# other options with the docker_daemon_options variable which is explained later.
+docker_users: []
+
+# Manage login credentials for 1 or more Docker registries. Example usage:
+# docker_registries:
+#     # Your registry URL is optional and defaults to the Docker Hub if undefined.
+#   - registry_url: "https://index.docker.io/v1/"
+#     # Your username is required.
+#     username: "your_docker_hub_username"
+#     # Your password is required.
+#     password: "your_docker_hub_password"
+#     # Your email address is optional (not all registries use it).
+#     email: "your_docker_hub@emailaddress.com"
+#     # Update your credentials. If undefined, this behavior will be skipped.
+#     reauthorize: False
+#     # Enable or disable these credentials by setting "present" or "absent".
+#     # If undefined, it will default to "present".
+#     state: "present"
+#     # The system user that will have access to the registry. If undefined it
+#     # will default to the root user. You likely want to set this to be a user
+#     # defined in your docker_users list above.
+#     system_user: "a_user_defined_in_docker_users"
+docker_registries: []
+
+# Docker daemon options as they would appear on the command line, such as:
+# docker_daemon_options:
+#   - "--dns 8.8.8.8"
+docker_daemon_options: []
+
+# Can be used to set environment variables for the Docker daemon, such as:
+# docker_daemon_environment:
+#   - "HTTP_PROXY=http://proxy.example.com:3128/"
+#   - "HTTPS_PROXY=http://proxy.example.com:3128/"
+#   - "NO_PROXY=localhost,127.0.0.1"
+docker_daemon_environment: []
+
+# Manage 1 or more cron jobs to perform Docker related system tasks. By default
+# this will safely clean up disk space used by Docker every Sunday at midnight.
+docker_cron_tasks:
+  - job: docker system prune -f &> /dev/null
+    name: "Docker disk clean up"
+    schedule: ["0", "0", "*", "*", "0"]
+
+# A list of packages that Docker requires to run. Typically you shouldn't have
+# to modify this list, but if Docker's dependencies change it can be updated
+# here without having to fork the role.
+docker_package_dependencies:
+  - "apt-transport-https"
+  - "ca-certificates"
+  - "software-properties-common"
+  - "gnupg2"
+  - "cron"
+
+# The Docker GPG key id used to sign the Docker package.
+docker_apt_key_id: "9DC858229FC7DD38854AE2D88D81803C0EBFCD88"

+# The Docker GPG key server address.
+docker_apt_key_server: "https://download.docker.com/linux/{{ ansible_distribution | lower }}/gpg"
+
+# The Docker APT repository.
+docker_apt_repository: "deb [arch=amd64] https://download.docker.com/linux/{{ ansible_distribution | lower }} {{ ansible_distribution_release }} {{ docker_channel }}"
+
+# How long should the apt-cache last in seconds?
+docker_apt_cache_time: 86400
+```
+
+## Example usage
+
+For the sake of this example let's assume you have a group called **app** and
+you have a typical `site.yml` file.
+
+To use this role edit your `site.yml` file to look something like this:
+
+```
+---
+
+- name: Configure app server(s)
+  hosts: "app"
+  become: True
+
+  roles:
+    - { role: "ansible-docker", tags: ["docker"] }
+```
+
+Here's a few examples. You can recreate this example on your end by opening or
+creating `group_vars/app.yml` which is located relative to your `inventory`
+directory and  then making it look like this:
+
+```
+---
+
+# Pin Docker version 18.06 from the stable channel.
+docker_version: "18.06"
+
+# Allow the admin and zerocool users to access Docker without needing root access.
+docker_users: ["admin", "zerocool"]
+
+# A couple of examples of authenticating to a Docker registry.
+docker_registries:
+  # Authenticate to the Docker Hub, and allow the "admin" system user acces to it:
+  - username: "your_docker_hub_username"
+    password: "your_docker_hub_password"
+    email: "your_docker_hub@emailaddress.com"
+    system_user: "{{ docker_users | first }}"
+  # Authenticate to some other private registry and allow "zerocool":
+  - registry_url: "https://your-registry.com"
+    username: "some_other_username"
+    password: "some_other_password"
+    system_user: "zerocool"
+  # Disable logging in to some old registry you don't use anymore:
+  - registry_url: "https://old-registry.com"
+    username: "some_old_username"
+    password: "some_old_password"
+    state: "absent"
+```
+
+Now you would run `ansible-playbook -i inventory/hosts site.yml -t docker`.
