Diagnosing failed Kubernetes deployments

Problem#

A deployment fails, but its top-level status does not explain why.

Solution#

Inspect the pods in the relevant namespace with kubectl get pods -n <namespace>, then inspect a failing pod with kubectl describe pod <pod> -n <namespace> and the deployment with kubectl describe deployment <deployment> -n <namespace>.

Failure Modes#

• Inspecting the wrong namespace can make resources appear missing.
• Checking only the deployment can miss pod-level status and events.
