Problem

New pods never start because the image cannot be downloaded from the registry.

Root Cause

The image tag is wrong or the namespace does not have a valid imagePullSecret.

Fix

Code

kubectl get secret regcred -n apps
kubectl patch serviceaccount default -n apps -p '{"imagePullSecrets":[{"name":"regcred"}]}'
kubectl set image deployment/web web=registry.example.com/web:2026.04.26 -n apps
kubectl rollout status deployment/web -n apps

Result

Pods start pulling the corrected image and transition to Running.
