The way I've done this is a little hack, but it works :)
You can use any of run/sudo/put/etc in the block too
def run_for_hosts(hosts)
hosts.each do |h|
task "run_for_#{h}", :hosts => h do
yield h
end
eval "run_for_#{h}"
end
end
task :my_task do
run_for_hosts(['staging', 'host2']) do
run "echo hi"
end
end
Hope this helps,
Matt
