capistrano-hostmenu

A capistrano plugin which allows you to choose one or more server to deploy via a text menu.

Here's an example:

In you deploy config:

server 'example1.com', user: "#{fetch(:deploy_user)}", roles: %w{web app}
server 'example2.com', user: "#{fetch(:deploy_user)}", roles: %w{web app}

when you run cap deploy or cap deploy:start or other deploy tasks, you will see a menu:

Please choose which server(s) to deploy:
  [1] example1.com
  [2] example2.com
  [3] all (default)
Please enter host_numbers (3):

you can answer with:

• 1 for choosing server example1.com,
• 2 for example2.com,
• 3 or 1,2 for both.
