Any capistrano email recipes?

I’d like to set up capistrano to send an email whenever we do a
deployment. Just start an SMTP session with localhost and shoot off
the email. I have all the code to do that actually, I just don’t know
how to run some Ruby code on the deployment server. Anyone know how
to do that, or do you have an email recipe?

Hey Pat-

Here is a method you can use to run ruby code on the remote server:

def ruby(cmd, options={}, &block)
temp_name = random_string + “.rb”
begin
put(cmd, temp_name, :mode => 0700)
send(run_method, “ruby #{temp_name}”, options, &block)
ensure
delete temp_name
end
end

then in a recipe:

task :foo do
ruby “puts ‘hello world!’”
ruby <<-RUBY
1.upto(10).do |i|
pust i
end
RUBY
end

Cool, thanks, that worked. Until I needed to load up some stuff from
the rails environment. Decided to use ActionMailer instead of just
doing the SMTP connection. Anyway, I created a cap plugin:

module CapistranoRunner
def runner(cmd)
run “#{release_path}/script/runner “#{cmd}” -e production”
end
end
Capistrano.plugin :runner, CapistranoRunner

and then to use it it looks like

task :after_deploy do
runner.runner “CapistranoMailer.deliver_deploy(:revision =>
#{revision})”
cleanup
end
