Here are capistrano extensions to be used with master-chef

• Add master-cap to your Gemfile
• Load master-cap in your Capfile: require 'master-cap'
• Choose a topology driver and load it ** on :load, :load_topology_directory ** Create a subdirectory named topology, and add your toplogy YAML files into
• Enjoy :)

Example of a topology file: integ.yml

:topology:
  :app:
    :hostname: my_app_server.mydomain.net
    :type: linux_chef
    :roles:
      - app_server
  :db:
    :hostname: db_server.mydomain.net
    :type: linux_chef
    :roles:
      - db_server
  :redis:
    :hostname: redise.mydomain.net
    :type: linux_chef
    :roles:
      - redis_server
:cap_override:
  :my_specific_cap_param: 'toto'
:default_role_list:
  - base

• cap integ show
• cap app-integ show
• cap integ_db_server show

• cap integ check: try to connect on each nodes with ssh
• cap integ ssh_cmd -s cmd=uname: exec unamecommand on each nodes

If you use only master-chef (no custom repo with Chef recipes), you have nothing to do.

If you use a custom repo, please add following lines before requiring master-cap

set :git_repos_manager_class, 'SimpleGitReposManager'

set :git_repos, [
  {
    :url => "http://github.com/octo-technology/master-chef.git",
    :ref => "aa597911b6d394dff27338c825aa966105cb6607",
  },
  {
    :url => "git@github.com:xxxx/yyyy.git",
    :local_path => "../yyyy",
  }
]

Note:

• :ref is used to lock master-chef version
• :local_path is used to run chef:local

• cap integ chef: run chef on all servers
• cap app-integ chef:local: run chef on app server, using local recipes. Usefull for debugging.
• cap app-integ chef:generate_local_json: generate the local.json file using current topology.
• cap app-integ chef:stack: output last chef stack trace
• cap integ chef:stack: purge all master-chef git repos caches
