Epitaph
Don’t outsource to automation because it’s easy, or because you don’t know how to do it. You won’t learn anything — and you’ll forget how the system actually works.
Learn the stack beneath the tool.
Remember: Ansible is just Python wrapped up nice, and Puppet’s Ruby underneath — which is even worse.
And don’t even get me started on containers, where the learning curve is nil and the abstraction is deep.
Always build on the lowest denominator — it survives everywhere. There’s no need for a framework just to clear your log files every seven days.
And most of all, remember the Bus Rule — if you’re not around, your code should still explain itself to the next human in line.
Rooted. And always keep it human.
Because sometimes you have to be root to do stuff.
