capistrano使用sudo运行内部命令

Question

Our capistrano setup is: ssh with regular user, but deploy to a location requiring sudo permissions to create files.

I want to run the specific capistrano command run "cd #{configuration[:releases_path]} && #{decompress(remote_filename).join(" ")} && rm #{remote_filename}" using sudo. Is there a neat way to over ride it?

def distribute!
  upload(filename, remote_filename)
  run "cd #{configuration[:releases_path]} && #{decompress(remote_filename).join(" ")} && rm #{remote_filename}"
end

Answer 1

I believe you can use the "sudo" function inside capistrano eg

def distribute!
  upload(filename, remote_filename)
  sudo "cd #{configuration[:releases_path]} && #{decompress(remote_filename).join(" ")} && rm #{remote_filename}"
end

Answer 2

The following workaround made it work.

task :self_own_dirs do
  sudo "chown -R #{user} #{releases_path}/.."
end

before 'deploy:update_code', 'deploy:self_own_dirs'
