A book - probably not so much.

The big value of sites (mostly github master repos) that offer recipes for saltstack/chef/ansible/puppet, or the helm collective, etc - are that they're continually being tweaked as new versions of (upstream) software are released.

They usually all require a fair bit of localisation before they 'just work', at least in my experience, but the template taken from a proven functioning system, and then abstracted & shared, is worth its weight in gold.

I've set up a few nomad jobs, but nothing anywhere as complex as, say, this cortexmetrics monstrosity. Even our k8s & nomad guru baulks at such an undertaking.
