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.

This cookbook provides a simple deploy_artifact resource that will deploy a single binary or tar.gz file. The deployment process is designed to mirror the Deploy Resource except designed to be used only for local deployments and not GIT. It is assumed that a directory called cached-copy will already contain the contents of what is to be deployed if not configured. It is left up to you on how to deliver the artifact using the while the resource will do the work to deploy it. The resource determines whether a file should be deployed or not based off of the current cached-copy checksum and the current release directory checksum name. Mac PAX format tar files are not supported at this time.

Given a file location and path, the resource will by default:
- Create a directory structure:

current -> releases\<CHECKSUM>

- Assume the file is a single binary, gziped gnu-tar or gnu-tar file
- Create a cached-copy directory and expect the file to be present or use the deploy_file callback to create file.
- Create a releases directory and release directory named as the MD5 checksum of the deployed file in path.
- On successful completion, symlink the release directory releases\<CHECKSUM> to path\current.


  • deploy_artifact - performs deployment of a local artifact on a server


  • deploy: default action, will deploy a given file to a given path


Resource Parameters for :deploy

  • name : defaults to file parameter
  • file : path to binary or tar.gz file to deploy, Required
  • path : path to location to deploy to, Default: /opt
  • owner : owner of the deployed files, Default: root
  • group : group of the deployed files, Default: root
  • cache_path : path to cache latest deployed file, Default: {path}/cached-copy
  • keep_releases : number of releases to keep or false to keep none, Default: 5
  • deploy_file : callback which takes a Ruby block of code to execute and deploy a file which is expected to be in cache_path.
  • before_symlink : callback which takes a Ruby block of code to execute before symlinking a release to current, Default: nothing
  • restart_command : callback which takes a Ruby block of code to execute after symlinkinga release to current which can be used to restart applications if needed, Default: nothing

Methods Available for Callbacks

Within a Ruby block used with one of the provided callbacks, you may use the following methods to determine path or files you may wish to act on. From a library perspective, they are resource values compiled during the resource execution, not from before or after.
- cache_path : path being used to deploy from
- cached_file : path of file calculated from file parameter and cache_path method
- cached_checksum : calculated checksum of cached_file
- releases_directory : path of parent releases directory calculated by appending releases to path paramter
- release_directory : path of current release being deployed from releases_directory and cached_checksum


Deploy tarball from Rackspace Cloud Files

deploy_artifact 'deploy.tar.gz' do
  path '/var/www/app'
  action :deploy
  deploy_file do
    rackspacecloud_file '/var/www/app/cached-copy/deploy.tar.gz' do
      directory 'deploy.tar.gz'
      rackspace_username 'username'
      rackspace_api_key 'api_key'
      rackspace_region 'dfw'
      action :create

Deploy tarball and restart service

deploy_artifact 'deploy.tar.gz' do
  path '/var/www/app'
  action :deploy
  deploy_file do
    rackspacecloud_file '/var/www/app/cached-copy/deploy.tar.gz' do
      directory 'deploy.tar.gz'
      rackspace_username 'username'
      rackspace_api_key 'api_key'
      rackspace_region 'dfw'
      action :create
  restart_command do
    service 'unicorn-app' do
      action :restart

Deploy tarball to a specific cache_path

deploy_artifact 'deploy.tar.gz' do
  path '/var/www/app'
  cache_path '/tmp'
  action :deploy
  deploy_file do
    rackspacecloud_file '/var/www/app/cached-copy/deploy.tar.gz' do
      directory 'deploy.tar.gz'
      rackspace_username 'username'
      rackspace_api_key 'api_key'
      rackspace_region 'dfw'
      action :create
