Frequently Asked Questions
What gets validated?
apiVersion/kind correctness, metadata.name presence, container image/pull policy, probe definitions, and resource requests/limits shape. Each finding names the fix.
Why do pods CrashLoop?
Top causes: wrong image tag, missing env/configmap keys, and failed probes. Validate manifests first, then check events and logs.
Dry-run too?
Yes — follow validation with kubectl apply --dry-run=client locally. Two gates catch what one misses.
Are manifests uploaded?
No — validation runs locally in your browser. Configs never leave your device.
