[cap3] How to deploy as another user

[Paul Schreiber]

Versions:

• Ruby 2.1
• Capistrano 3.1

Platform:

• working on OS X 10.9.1
• deploy to CentOS 6.5

On my target deployment server, i cannot ssh in as my deploy user, admin@myserver, but I can ssh in as paul@myserver and then sudo su - admin.

I made a test task

  task :sayhello do

    on roles(:app) do

      as "admin" do

        puts capture "whoami"

      end

    end

  end

And that works as expected:

$ cap beta deploy:sayhello 

DEBUG [acaa0e6a] Running /usr/bin/env if ! sudo su admin -c whoami > /dev/null; then echo "You cannot switch to user 'admin' using sudo, please check the sudoers file" 1>&2; false; fi on awse-tweb01.foo.com

DEBUG [acaa0e6a] Command: if ! sudo su admin -c whoami > /dev/null; then echo "You cannot switch to user 'admin' using sudo, please check the sudoers file" 1>&2; false; fi

DEBUG [acaa0e6a] Finished in 6.982 seconds with exit status 0 (successful).

DEBUG [153b980d] Running /usr/bin/env whoami on awse-tweb01.foo.com

DEBUG [153b980d] Command: sudo su admin -c "/usr/bin/env whoami"

DEBUG [153b980d] admin

DEBUG [153b980d] Finished in 0.535 seconds with exit status 0 (successful).

admin

How can I have Capistrano run the deploy tasks as admin?

  i.e. prefixed with sudo su admin -c or sudo su the shell before running commands

You might try replacing the defaults in the SSHKit command map with a command that does what you need. If you can't SSH in as your deploy user, that's not a deploy user. Fix the permissions for your `paul` account.
