Capistrano 3 sudo task

Question

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         


        

Answer 1

I usually write like this:

task :hello do
  on roles(:all) do |host|
    execute :sudo, :cp, '~/something', '/something'
  end
end

Edit

Capistrano 3 does not support sudo with password.

However, I created a small gem, which enables you to use sudo with password in Capistrano 3 task.

Add sshkit-sudo to your application's Gemfile:

# Gemfile
gem 'sshkit-sudo'

And require 'sshkit/sudo' in you Capfile:

# Capfile
require 'sshkit/sudo'

Now, you can execute a command with sudo as follows:

task :hello do
  on roles(:all) do
    sudo :cp, '~/something', '/something'
  end
end
