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.
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.
Git says it can't find a repo where you're standing. Nine times out of ten it's the wrong directory, a missing .git, or an ownership check.
Two failures wear the same face: builds that rebuild everything every time, and builds that hand you a stale image. Both trace back to how layer caching keys work.
Git refuses to switch branches or pull because uncommitted edits are in the way. Here's how to move them safely, and when it's fine to throw them out.
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.
How pods can talk to AWS, GCP, and Azure with no static keys — using audience-bound projected ServiceAccount tokens and the cluster OIDC issuer.
A pod sits Pending and the scheduler quietly logs why it rejected every node. Learn to read that one line and fix the real cause instead of guessing.
Evicted pods are the kubelet telling you a node ran out of something. Here's how to read the signal, stop the bleeding, and keep it from happening again.
HashiCorp relicensed Terraform and a community fork spun up overnight. Here's how OpenTofu actually differs and which one your team should run.
Your push bounces because the remote moved on without you. Here is how to catch up cleanly, when to rebase versus merge, and when a force-push is actually safe.
We ran the same test suite on both platforms for a year. Here's where CircleCI earns its price, where GitHub Actions wins on simplicity, and what the bill actually looks like.
