Dynamic deploy_to

[Juan Carlos Roca]

Versions:

• Ruby 1.9.3p194
• Capistrano 3.2.1

Platform:

• Working on Node.js

Files:

• Capfile
• deploy.rb
• Stage files (production.rb, staging.rb)

Im deploying to a single server and having it run several node processes, so Im having each process as an individual server on the config and I wish to define a per server :deploy_to variable how could I do this?

Also when I setup a server with the Extended Server Syntax "server 'server.com', user: 'user', roles: %w{app}" how can I fetch the user variable?

You can't really, the idea is that each deploy is the same, everywhere. That said, if you are having a really custom deployment, you can use Rake+SSHKit to do whatever you need, see some of the examples: https://github.com/capistrano/sshkit/blob/master/EXAMPLES.md

Hi Juan,

to fetch the user for a server you can try something like this:

task :test_task do
  on roles :all do |host|
    my_user = host.user
  end
end

or to get all users:

task :test_task_all_users do
  users_array = roles(:all).map(&:user)
end

Hope that helps.

As for the general solution - you should be better off by following Lee's advice.
