Most Docker time is spent fighting the same handful of errors. This is the map: what each one means, the command that reveals the cause, and the fix.
Woodpecker forked Drone when the license changed. Here's how the two compare for small teams and homelabs that just want simple container-native CI.

The Compose failures that eat an afternoon are almost always the same six. Here's how to spot each one fast and the fix that actually sticks.
A bloated build context slows every build, wrecks your cache, and quietly leaks secrets into images. Here's how to keep it lean.

A pod stuck in CreateContainerConfigError means kubelet can't build the container config, almost always a ConfigMap or Secret reference that doesn't line up.
The container starts, then dies with "exec format error." Here's why the CPU architecture is wrong, how to confirm it, and how to build images that just run.
Every crash loop leaves a number behind. Learn to read exit codes straight from kubectl describe and know the fix before you open the logs.
Exit 137 usually means the kernel shot your container for eating too much memory. Here's how to confirm the OOM kill and stop it happening again.
