Deploy only one role / server with capistrano

Question

I am trying to configure multiple roles, one for live and one for dev. They look like this:

role :live, "example.com"
role :dev, "dev.example.com"

However, when I start the cover deployment, it runs for both servers. I tried the following and it always runs on both.

cap deploy live
cap ROLE=live deploy

What am I missing? I know that I can write a custom task that responds to only one role, but I do not want to write a whole bunch of tasks to tell her to respond to one role. Thank!

task :dev do
    role :env, "dev.example.com"
end

task :prod do
    role :env, "example.com"
end

cap dev deploy
cap prod deploy

Answer 4

Another hint: if you use multi-stage, do not forget to specify ROLES constant before the command cap.

ROLES=web cap production deploy

or after wednesday

cap production ROLES=web deploy

If you set the first parameter, multistage will consider it as the name of the scene and replace it by default:

cap ROLES=web production deploy

* [...] executing `dev'
* [...] executing `production'
