Auxiliary helper method for the `deploy:check' task. Lets you set up your own dependencies.
# File lib/railsless-deploy.rb, line 77 def depend(location, type, *args) deps = fetch(:dependencies, {}) deps[location] ||= {} deps[location][type] ||= [] deps[location][type] << args set :dependencies, deps end
logs the command then executes it locally. returns the command output as a string
# File lib/railsless-deploy.rb, line 96 def run_locally(cmd) logger.trace "executing locally: #{cmd.inspect}" if logger `#{cmd}` end
Same as sudo, but tries sudo with :as set to the value of the :runner variable (which defaults to "app").
# File lib/railsless-deploy.rb, line 134 def try_runner(*args) options = args.last.is_a?(Hash) ? args.pop : {} args << options.merge(:as => fetch(:runner, "app")) try_sudo(*args) end
If a command is given, this will try to execute the given command, as described below. Otherwise, it will return a string for use in embedding in another command, for executing that command as described below.
If :run_method is :sudo (or :use_sudo is true), this executes the given command via sudo. Otherwise is uses run. If :as is given as a key, it will be passed as the user to sudo as, if using sudo. If the :as key is not given, it will default to whatever the value of the :admin_runner variable is, which (by default) is unset.
THUS, if you want to try to run something via sudo, and what to use the root user, you'd just to try_sudo('something'). If you wanted to try_sudo as someone else, you'd just do try_sudo('something', :as => "bob"). If you always wanted sudo to run as a particular user, you could do set(:admin_runner, "bob").
# File lib/railsless-deploy.rb, line 116 def try_sudo(*args) options = args.last.is_a?(Hash) ? args.pop : {} command = args.shift raise ArgumentError, "too many arguments" if args.any? as = options.fetch(:as, fetch(:admin_runner, nil)) via = fetch(:run_method, :sudo) if command invoke_command(command, :via => via, :as => as) elsif via == :sudo sudo(:as => as) else "" end end
