Summary#
Kubernetes deployment failure triage
Problem#
A deployment fails to come up, but the root cause is unclear from the deployment command alone.
Solution#
Start with kubectl get pods in the target namespace, watch pod state changes, then inspect both the pod and deployment with kubectl describe. Use the pod name from get pods to read scheduling, image pull, event, and restart details before changing manifests.
Failure Modes#
- Looking only at the deployment object can miss pod-level errors such as image pull or scheduling failures
- Not scoping commands to the correct namespace leads to false negatives
- Treating restart count as the root issue instead of reading pod events delays diagnosis
