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.
