Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

Docker Platform Cookbook

Description

Docker is an open-source project that automates the deployment of
applications inside software containers, by providing an additional layer of
abstraction and automation of operating-system-level virtualisation on Linux.
Docker uses the resource isolation features of the Linux kernel such as cgroups
and kernel namespaces, and a union-capable file system such as aufs and others
to allow independent "containers" to run within a single Linux instance,
avoiding the overhead of starting and maintaining virtual machines.

This cookbook provides recipes to install and configure Docker with
configuration stored in attributes. It uses yum-docker cookbook to install
official repository and it wraps docker cookbook resources to control
Docker status.

Requirements

Cookbooks and gems

Declared in [metadata.rb](metadata.rb) and in [Gemfile](Gemfile).

Platforms

  • RHEL Family 7, tested on Centos

Note: by composing it with apt-docker cookbook, it should work fine on
Debian / Ubuntu.

Usage

Test

This cookbook is fully tested in test-kitchen, using the vagrant driver and
inspec verifier.

For more information, see [.kitchen.yml](.kitchen.yml) and [test](test)
directory.

Attributes

Configuration is done by overriding default attributes. All configuration keys
have a default defined in [attributes/default.rb](attributes/default.rb).
Please read it to have a comprehensive view of what and how you can configure
this cookbook behavior.

In addition, you can use attributes to define docker cookbook resources.
All you have to do is to define an attribute of the same name as the resource
you want to call containing the different instances of this resource. For
instance:

"docker_volume": {
  "data": {
    "action": "create"
  },
  "to_remove": {
    "action": "remove"
  }
}

It creates a docker volume named data and remove the one called to_remove.
The key of each sub hash table is the name attribute and the value is an hash
table containing the resource configuration, mapping exactly the attribute name
defined in docker cookbook documentation.

If you need multiple arguments for an attribute, you have to declare them in
an array. If you need an array as single argument, add an extra array.

For instance:

"docker_container": {
  "my_alpine": {
    "container_name": "alpine",
    "repo": "alpine",
    "volumes": [["data:/data"]],
    "action": "run",
    "subscribes": ["redeploy", "docker_image[alpine]", "immediately"]
  }
}

You can find other examples in [.kitchen.yml](.kitchen.yml) file.

Recipes

default

Include repository, package, service and docker recipes.

repository

Use yum-docker cookbook to install official yum repository.

package

Install docker-engine package or upgrade it if attribute version is set to
latest.

service

Enable and start docker service. Restart it if package was upgraded.

docker

Wrap all docker cookbook resources so it is possible to use them with
attributes. Read attributes section for more details.

Resources/Providers

None.
