[chef] Re: bash -> chef

Have a look at the new relic cookbook at https://github.com/heavywater/chef-newrelic

I've been trying to wrap my head around chef and translating what
would be a trivial bash script into the chef equivalent.

The goal is to include NewRelic's host server (not application)
monitoring on an Ubuntu box.

The bash process:

   # Grab New Relic's apt sources.list fragment and tuck it away in
/etc/apt/sources.list.d
   wget -O /etc/apt/sources.list.d/newrelic.list
http://download.newrelic.com/debian/newrelic.list
   # Get their signing key (value previously ascertained)
   apt-key adv --keyserver hkp://subkeys.pgp.net --recv-keys 548C16BF
   # Run apt-get update and install package
   apt-get update
   apt-get install newrelic-sysmond
   # Set your license key (presumably stuffed in an encrypted data bag)
   nrsysmond-config --set license_key=<% key_ID %>
   # Launch the daemon
   /etc/init.d/newrelic-sysmond start

The easiest JGID method would be to write a ruby wrapper around the
bash.  For parts of this I find chef methods.

There's an "apt" cookbook which can do some things, including adding a
sources.list line, but apparently not downloading a sources.list.d/
fragment from a known URL.  Am I missing something?

The apt cookbook provides for getting the signing key:

   apt_repository "newrelic-servermon" do
       keyserver "keyserver.pgp.edu"
       key "548C16BF"
   end

Running the config step looks like another shell wrapper.

The service resource should be able to start the daemon:

   service "newrelic-servermon" do
       supports :status -> true, :restart => true, :reload => true
       action [:enable, :start]
   end


A nice "plus" feature would be an easy way to add, say, "monit"
monitoring and possibly Nagios configuration for any given service,
rather than managing these separately in a Nagios recipe.


TIA.
