## What is ansible-docker? [](http://travis-ci.org/nickjj/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 using PIP (version pinning is supported)
|
|
||||||
- Install the `docker` PIP package so Ansible's `docker_*` modules work
|
|
||||||
- Manage Docker registry login credentials
|
|
||||||
- Configure 1 or more users to run Docker without needing root access
|
|
||||||
- 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.
|
|
||||||
|
|
||||||
By the way, if you don't know what Docker is, or are looking to become an expert
|
|
||||||
with it then check out
|
|
||||||
[Dive into Docker: The Complete Docker Course for Developers](https://diveintodocker.com/?utm_source=ansibledocker&utm_medium=github&utm_campaign=readmetop).
|
|
||||||
|
|
||||||

|
|
||||||
|
|
||||||
- Ubuntu 16.04 LTS (Xenial)

latest release. [Switch to the latest release](https://github.com/nickjj/ansible-docker/tree/v1.8.0).*

|
|
||||||
|
|
||||||
## Quick start
|
|
||||||
|
|
||||||
The philosophy for all of my roles is to make it easy to get going, but provide
|
|
||||||
a way to customize nearly everything.
|
|
||||||
|
|
||||||
### What's configured by default?
|
|
||||||
|
|
||||||
The latest Docker CE and Docker Compose will be installed, Docker disk clean up
|
|
||||||
will happen once a week and Docker container logs will be sent to `journald`.
|
|
||||||
|
|
||||||
### Example playbook
|
|
||||||
|
|
||||||
```yml
|
|
||||||
---
|
|
||||||
|
|
||||||
# site.yml
|
|
||||||
|
|
||||||
- name: Example
|
|
||||||
hosts: "all"
|
|
||||||
become: true
|
|
||||||
|
|
||||||
roles:
|
|
||||||
- role: "nickjj.docker"
|
|
||||||
tags: ["docker"]
|
|
||||||
```
|
|
||||||
|
|
||||||
Usage: `ansible-playbook site.yml -t docker`
|
|
||||||
|
|
||||||
### Installation
|
|
||||||
|
|
||||||
`$ ansible-galaxy install nickjj.docker`
|
|
||||||
|
|
||||||
## Default role variables
|
|
||||||
|
|
||||||
### Installing Docker
|
|
||||||
|
|
||||||
#### Edition
|
|
||||||
|
|
||||||
Do you want to use "ce" (community edition) or "ee" (enterprise edition)?
|
|
||||||
|
|
||||||
```yml
|
|
||||||
docker__edition: "ce"
|
|
||||||
```
|
|
||||||
|
|
||||||
#### Channel
|
|
||||||
|
|
||||||
Do you want to use the "stable", "edge", "testing" or "nightly" channels? You
|
|
||||||
can add more than one (order matters).
|
|
||||||
|
|
||||||
```yml
|
|
||||||
docker__channel: ["stable"]
|
|
||||||
```
|
|
||||||
|
|
||||||
#### Version
|
|
||||||
|
|
||||||
- When set to "", the current latest version of Docker will be installed
|
|
||||||
- When set to a specific version, that version of Docker will be installed and pinned
|
|
||||||
|
|
||||||
```yml
|
|
||||||
docker__version: ""
|
|
||||||
|
|
||||||
# For example, pin it to 18.06.
|
|
||||||
docker__version: "18.06"
|
|
||||||
|
|
||||||
# For example, pin it to a more precise version of 18.06.
|
|
||||||
docker__version: "18.06.1"
|
|
||||||
```
|
|
||||||
|
|
||||||
*Pins are set with `*` at the end of the package version so you will end up
|
|
||||||
getting minor and security patches unless you pin an exact version.*
|
|
||||||
|
|
||||||
##### Upgrade strategy
|
|
||||||
|
|
||||||
- When set to `"present"`, running this role in the future won't install newer
|
|
||||||
versions (if available)
|
|
||||||
- When set to `"latest"`, running this role in the future will install newer
|
|
||||||
versions (if available)
|
|
||||||
|
|
||||||
```yml
|
|
||||||
docker__state: "present"
|
|
||||||
```
|
|
||||||
|
|
||||||
##### Downgrade strategy
|
|
||||||
|
|
||||||
The easiest way to downgrade would be to uninstall the Docker package manually
|
|
||||||
and then run this role afterwards while pinning whatever specific Docker version
|
|
||||||
you want.
|
|
||||||
|
|
||||||
```sh
|
|
||||||
# An ad-hoc Ansible command to stop and remove the Docker CE package on all hosts.
|
|
||||||
ansible all -m systemd -a "name=docker-ce state=stopped" \
|
|
||||||
-m apt -a "name=docker-ce autoremove=true purge=true state=absent" -b
|
|
||||||
```
|
|
||||||
|
|
||||||
### Installing Docker Compose
|
|
||||||
|
|
||||||
Docker Compose will get PIP installed inside of a Virtualenv. This is covered
|
|
||||||
in detail in another section of this README file.
|
|
||||||
|
|
||||||
#### Version
|
|
||||||
|
|
||||||
- When set to "", the current latest version of Docker Compose will be installed
|
|
||||||
- When set to a specific version, that version of Docker Compose will be installed
|
|
||||||
and pinned
|
|
||||||
|
|
||||||
```yml
|
|
||||||
docker__compose_version: ""
|
|
||||||
|
|
||||||
# For example, pin it to 1.23.
|
|
||||||
docker__compose_version: "1.23"
|
|
||||||
|
|
||||||
# For example, pin it to a more precise version of 1.23.
|
|
||||||
docker__compose_version: "1.23.2"
|
|
||||||
```
|
|
||||||
|
|
||||||
*Upgrade and downgrade strategies will be explained in the other section of this
|
|
||||||
README.*
|
|
||||||
|
|
||||||
### Configuring users to run Docker without root
|
|
||||||
|
|
||||||
A list of users to be added to the `docker` group.
|
|
||||||
|
|
||||||
Keep in mind this user needs to already exist, this role will not create it. If
|
|
||||||
you want to create users, check out my
|
|
||||||
[user role](https://github.com/nickjj/ansible-user).
|
|
||||||
|
|
||||||
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 server since they can run Docker
|
|
||||||
without `sudo` and volume mount in any path 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_json` variable which is explained later.
|
|
||||||
|
|
||||||
```yml
|
|
||||||
# Try to use the sudo user by default, but fall back to root.
|
|
||||||
docker__users: ["{{ ansible_env.SUDO_USER | d('root') }}"]
|
|
||||||
|
|
||||||
# For example, if the user you want to set is different than the sudo user.
|
|
||||||
docker__users: ["admin"]
|
|
||||||
```
|
|
||||||
|
|
||||||
### Configuring Docker registry logins
|
|
||||||
|
|
||||||
Login to 1 or more Docker registries (such as the
|
|
||||||
[Docker Hub](https://hub.docker.com/)).
|
|
||||||
|
|
||||||
```yml
|
|
||||||
docker__registries:
|
|
||||||
- #registry_url: "https://index.docker.io/v1/"
|
|
||||||
username: "your_docker_hub_username"
|
|
||||||
password: "your_docker_hub_password"
|
|
||||||
#email: "your_docker_hub@emailaddress.com"
|
|
||||||
#reauthorize: false
|
|
||||||
#config_path: "$HOME/.docker/config.json"
|
|
||||||
#state: "present"
|
|
||||||
docker__registries: []
|
|
||||||
```
|
|
||||||
|
|
||||||
*Properties prefixed with \* are required.*
|
|
||||||
|
|
||||||
- `registry_url` defaults to `https://index.docker.io/v1/`
|
|
||||||
- *`username` is your Docker registry username
|
|
||||||
- *`password` is your Docker registry password
|
|
||||||
- `email` defaults to not being used (not all registries use it)
|
|
||||||
- `reauthorize` defaults to `false`, when `true` it updates your credentials
|
|
||||||
- `config_path` defaults to `(ansible_env.PWD | d('/root')) + '/.docker/config.json'`
|
|
||||||
- `state` defaults to "present", when "absent" the login will be removed
|
|
||||||
|
|
||||||
### Configuring the Docker daemon options (json)
|
|
||||||
|
|
||||||
Default Docker daemon options as they would appear in `/etc/docker/daemon.json`.
|
|
||||||
|
|
||||||
```yml
|
|
||||||
docker__default_daemon_json: |
|
|
||||||
"log-driver": "journald"
|
|
||||||
|
|
||||||
# Add your own additional daemon options without overriding the default options.
|
|
||||||
# It follows the same format as the default options, and don't worry about
|
|
||||||
# starting it off with a comma. The template will add the comma if needed.
|
|
||||||
docker__daemon_json: ""
|
|
||||||
```
|
|
||||||
|
|
||||||
### Configure the Docker daemon options (flags)
|
|
||||||
|
|
||||||
Flags that are set when starting the Docker daemon cannot be changed in the
|
|
||||||
`daemon.json` file. By default Docker sets `-H unix://` which means that option
|
|
||||||
cannot be changed with the json options.
|
|
||||||
|
|
||||||
Add or change the starting Docker daemon flags by supplying them exactly how
|
|
||||||
they would appear on the command line.
|
|
||||||
|
|
||||||
```yml
|
|
||||||
# Each command line flag should be its own item in the list.
|
|
||||||
#
|
|
||||||
# Using a Docker version prior to 18.09?
|
|
||||||
# You must set `-H fd://` instead of `-H unix://`.
|
|
||||||
docker__daemon_flags:
|
|
||||||
- "-H unix://"
|
|
||||||
```
|
|
||||||
|
|
||||||
*If you don't supply some type of `-H` flag here, Docker will fail to start.*
|
|
||||||
|
|
||||||
### Configuring the Docker daemon environment variables
|
|
||||||
|
|
||||||
```yml
|
|
||||||
docker__daemon_environment: []
|
|
||||||
|
|
||||||
# For example, here's how to set a couple of proxy environment variables.
|
|
||||||
docker__daemon_environment:
|
|
||||||
- "HTTP_PROXY=http://proxy.example.com:80"
|
|
||||||
- "HTTPS_PROXY=https://proxy.example.com:443"
|
|
||||||
```
|
|
||||||
|
|
||||||
### Configuring advanced systemd directives
|
|
||||||
|
|
||||||
This role lets the Docker package manage its own systemd unit file and adjusts
|
|
||||||
things like the Docker daemon flags and environment variables by using
|
|
||||||
the systemd override pattern.
|
|
||||||
|
|
||||||
If you know what you're doing, you can override or add to any of Docker's systemd
|
|
||||||
directives by setting this variable. Anything you place in this string will be
|
|
||||||
written to `/etc/systemd/system/docker.service.d/custom.conf` as is.
|
|
||||||
|
|
||||||
```yml
|
|
||||||
docker__systemd_override: ""
|
|
||||||
```
|
|
||||||
|
|
||||||
### Configuring Docker related cron jobs
|
|
||||||
|
|
||||||
By default this will safely clean up disk space used by Docker every Sunday at
|
|
||||||
midnight.
|
|
||||||
|
|
||||||
```yml
|
|
||||||
# `a` removes unused images (useful in production).
|
|
||||||
# `f` forces it to happen without prompting you to agree.
|
|
||||||
docker__cron_jobs_prune_flags: "af"
|
|
||||||
|
|
||||||
docker__cron_jobs:
|
|
||||||
- name: "Docker disk clean up"
|
|
||||||
job: "docker system prune -{{ docker__cron_jobs_prune_flags }} > /dev/null 2>&1"
|
|
||||||
schedule: ["0", "0", "*", "*", "0"]
|
|
||||||
cron_file: "docker-disk-clean-up"
|
|
||||||
#user: "{{ (docker__users | first) | d('root') }}"
|
|
||||||
#state: "present"
|
|
||||||
```
|
|
||||||
|
|
||||||
*Properties prefixed with \* are required.*
|
|
||||||
|
|
||||||
- *`name` is the cron job's description
|
|
||||||
- *`job` is the command to run in the cron job
|
|
||||||
- *`schedule` is the [standard cron job](https://en.wikipedia.org/wiki/Cron#Overview)
|
|
||||||
format for every Sunday at midnight
|
|
||||||
- *`cron_file` writes a cron file to `/etc/cron.d` instead of a user's individual crontab
|
|
||||||
- `user` defaults to the first `docker__users` user or root if that's not available
|
|
||||||
- `state` defaults to "present", when "absent" the cron file will be removed
|
|
||||||
|
|
||||||
### Configuring the APT package manager
|
|
||||||
|
|
||||||
Docker requires a few dependencies to be installed for it to work. You shouldn't
|
|
||||||
have to edit any of these variables.
|
|
||||||
|
|
||||||
```yml
|
|
||||||
# List of packages to be installed.
|
|
||||||
docker__package_dependencies:
|
|
||||||
- "apt-transport-https"
|
|
||||||
- "ca-certificates"
|
|
||||||
- "cron"
|
|
||||||
- "gnupg2"
|
|
||||||
- "software-properties-common"
|
|
||||||
|
|
||||||
# The Docker PGP key id used to sign the Docker package.
|
|
||||||
docker__apt_key_id: "9DC858229FC7DD38854AE2D88D81803C0EBFCD88"
|
|
||||||
|
|
||||||
# The Docker PGP key server address.
|
|
||||||
docker__apt_key_url: "https://download.docker.com/linux/{{ ansible_distribution | lower }}/gpg"
|
|
||||||
|
|
||||||
# The Docker upstream APT repository.
|
|
||||||
docker__apt_repository: >
|
|
||||||
deb [arch=amd64]
|
|
||||||
https://download.docker.com/linux/{{ ansible_distribution | lower }}
|
|
||||||
{{ ansible_distribution_release }} {{ docker__channel | join (' ') }}
|
|
||||||
```
|
|
||||||
|
|
||||||
### Installing Python packages with Virtualenv and PIP
|
|
||||||
|
|
||||||
#### Configuring Virtualenv
|
|
||||||
|
|
||||||
Rather than pollute your server's version of Python, all PIP packages are
|
|
||||||
installed into a Virtualenv of your choosing.
|
|
||||||
|
|
||||||
```yml
|
|
||||||
docker__pip_virtualenv: "/usr/local/lib/docker/virtualenv"
|
|
||||||
```
|
|
||||||
|
|
||||||
#### Installing PIP and its dependencies
|
|
||||||
|
|
||||||
This role installs PIP because Docker Compose is installed with the
|
|
||||||
`docker-compose` PIP package and Ansible's `docker_*` modules use the `docker`
|
|
||||||
PIP package.
|
|
||||||
|
|
||||||
```yml
|
|
||||||
# This will attempt to install the correct version of PIP based on what your
|
|
||||||
# configured Ansible Python interpreter is set to (ie. Python 2 or 3).
|
|
||||||
docker__pip_dependencies:
|
|
||||||
- "python-setuptools"
|
|
||||||
- "python{{ '3' if ansible_python.version.major == 3 else '' }}-pip"
|
|
||||||
```
|
|
||||||
|
|
||||||
#### Installing PIP packages
|
|
||||||
|
|
||||||
```yml
|
|
||||||
docker__default_pip_packages:
|
|
||||||
- name: "docker"
|
|
||||||
state: "{{ docker__pip_docker_state }}"
|
|
||||||
- name: "docker-compose"
|
|
||||||
version: "{{ docker__compose_version }}"
|
|
||||||
path: "/usr/local/bin/docker-compose"
|
|
||||||
src: "{{ docker__pip_virtualenv + '/bin/docker-compose' }}"
|
|
||||||
state: "{{ docker__pip_docker_compose_state }}"
|
|
||||||
|
|
||||||
# Add your own PIP packages with the same properties as above.
|
|
||||||
docker__pip_packages: []
|
|
||||||
```
|
|
||||||
|
|
||||||
*Properties prefixed with \* are required.*
|
|
||||||
|
|
||||||
- *`name` is the package name
|
|
||||||
- `version` is the package version to be installed (or "" if this is not defined)
|
|
||||||
- `path` is the destination path of the symlink
|
|
||||||
- `src` is the source path to be symlinked
|
|
||||||
- `state` defaults to "present", other values can be "forcereinstall" or "absent"
|
|
||||||
|
|
||||||
##### PIP package state
|
|
||||||
|
|
||||||
- When set to `"present"`, the package will be installed but not updated on
|
|
||||||
future runs
|
|
||||||
- When set to `"forcereinstall"`, the package will always be (re)installed and
|
|
||||||
updated on future runs
|
|
||||||
- When set to `"absent"`, the package will be removed
|
|
||||||
|
|
||||||
```yml
|
|
||||||
docker__pip_docker_state: "present"
|
|
||||||
docker__pip_docker_compose_state: "present"
|
|
||||||
```
|
|
||||||
|
|
||||||
#### Working with Ansible's `docker_*` modules
|
|
||||||
|
|
||||||
This role uses `docker_login` to login to a Docker registry, but you may also
|
|
||||||
use the other `docker_*` modules in your own roles. They are not going to work
|
|
||||||
unless you instruct Ansible to use this role's Virtualenv.
|
|
||||||
|
|
||||||
At either the inventory, playbook or task level you'll need to set
|
|
||||||
`ansible_python_interpreter: "/usr/bin/env python-docker"`. This works because
|
|
||||||
this role symlinks the Virtualenv's Python binary to `python-docker`.
|
|
||||||
|
|
||||||
You can look at this role's `docker_login` task as an example on how to do it
|
|
||||||
at the task level.
