Converting from Capistrano

• ‘set scm’ is removed. Vlad.load :scm => :something if you don’t use subversion.
• ‘task’ blocks are renamed to ‘remote_task’.
• Most variables are the same. See variables.txt for details.
• No with_command / sudo / via wonkiness
• Uses real ssh so env vars and the like are not a problem
  • no with_env as a result.
• Vlad doesn’t use ’:no_release’ or ’:primary’.
  • If you have a task that needs to run on only one host from a role, you should declare a new role for that host:

      role :master_db, "master.example.com"
    

    ..and then override the role for the task you want to limit:

      Rake::Task["mytask"].options[:roles] = :master_db
    

• The ‘host’ method can be used to consolidate multiple ‘role’ calls.
  • host “www.example.com“, :app, :web, :db specifies a host with three roles.
• migrate_env is now migrate_args.
• Vlad doesn’t have before/after magic add-on tasks.

BEFORE:

  set :application, "rubyholic"
  set :domain,      "zenspider.textdriven.com"
  set :repository,  "svn://svn.example.com/rubyholic/branches/stable"
  set :deploy_to,   "/users/home/zenspider/domains/new.rubyholic.com"

  set :user,        "zenspider"
  set :use_sudo,    false

  role :web, domain
  role :app, domain
  role :db,  domain, :primary => true

AFTER:

  set :domain,      "zenspider.textdriven.com"
  set :repository,  "svn://svn.example.com/rubyholic/branches/stable"
  set :deploy_to,   "/users/home/zenspider/domains/new.rubyholic.com"
