Capistrano 3 sudo task

capistrano, capistrano3, ruby-on-rails

Solution

The Capistrano 3 guide recommends the use of passwordless sudo. This allows your less-priveleged user execute the sudo command without having to enter a password via the PTY.

You can use the task that Kentaro wrote above, and add something like the following to your /etc/sudoers file:

deploy ALL=NOPASSWD:/bin/cp ~/something /something

Problem

I want to write a recipe with Capistrano 3 executing a task on the remote server with sudo. With Capistrano 2 this could be done for example: ``` default_run_options[:pty] = true task :hello do run "#{sudo} cp ~/something /something" end ``` With Capistrano 3 I found: ``` set :pty, true ``` But I could not get to execute a task running with sudo. How can I run a task with sudo?
