Specifically what I am getting at is a notification.
I have a deploy task that deploys the website to all my webheads.
Abbreviated task follows:
task :production do
set :default_environment {}
roles :app one.foo.com, two.foo.com, three.foo.com
deploy.notify_via_boxcar
end
This deploys to all 3 servers. I want a deploy notification (via
Boxcar) which is a deploy task. Originally I had it running via
"after 'deploy:update_code'", but that runs it on every machine. I
just want the notification to fire when the whole task of deploying to
all servers is complete. When I put it in the :production task (like
above), it doesn't do the normal deploy tasks. Where should I put it
to only fire on the completion? I remember reading something about
on :exit, but I couldn't find the docs to implement that.
