Written from production, not slideware.
PLATFORM OPS
Field notes from production, not slideware.
A free, open technical newsletter on Kubernetes, SRE and platform engineering. No paywall, no sign-in, no tracking — a tree of static pages generated from a handful of data files, with the source public.
It exists because the explanation I wanted usually did not. Writing the thing you had to work out yourself is the most reliable way to find out whether you actually understood it.
THE FULL SPREAD
Architecture to incident
Kubernetes workloads, config and access, scheduling, autoscaling and cluster operations. OpenShift architecture, networking, storage and operations. Service mesh fundamentals and operations.
362 commands
Linux, Kubernetes, Docker and OpenShift command references, grouped by the task you are actually doing rather than alphabetically.
Underneath it all
Computer fundamentals, operating systems, shell and bash, Python, and Git — the layer that explains why the layer above behaves as it does.
A terminal in the page
A Unix shell simulated over an in-memory filesystem, with exercises that check the state of the system rather than the string you typed.
ELSEWHERE
HAVE A PROBLEM IN THIS LAYER?
Specifics get a better answer than introductions — say what is actually happening and I will tell you what I would look at first.
