[chef] bash -> chef

[Edward Morbius < >]

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.
