Docker Operations
Docker on your machine and in your repo: the files you write (Dockerfile, .dockerignore,
compose.yaml) and the engine that runs them. Versions verified 2026-10-07 (Compose v5,
Docker Desktop 4.94, WSL 3.0, Podman 6); scripts/check-docker-facts.py --live re-checks
them weekly.
Why: the costly Docker mistakes are silent. A secret is copied into a layer, a datastore
listens on every interface, compose config pastes credentials into a log, a prune deletes
a volume someone needed. The rules below stop those first.
