[Capistrano] Re: Which server is this task being executed on?

[Jamis Buck]

Note that a task is not executed once per matching server, it is executed once, for all matching servers. So, depending on what you need:

  run "echo server is $CAPISTRANO:HOST$"



2. You want to know which servers a task is restricted to:

  servers = find_servers_for_task(current_task)
  puts "servers: #{servers.join(', ')}"

Hope that helps,

1. You simply want the host name to appear somewhere in a command you're running in the current task: The $CAPISTRANO:HOST$ text gets replaced with the actual hostname immediately before the command is executed on each server.

Hi all -

I've got a task that needs to know which server it's currently being
executed on.  Is there a variable containing this value that the task
can get at?  e.g.,

task :foobar, :roles => app do
 echo "I'm running on the server #{fetch(:something)}"
end

I could get this info by parsing out `hostname` or something, but was
hoping to avoid that... is there a "current_session" or something?

Thanks,

tom
