What Happened

Pods failed to pull images because the registry was down for maintenance, leading to deployment failures.

Diagnosis Steps

1Checked the pod status using kubectl describe pod and identified image pull errors.
2Investigated the registry status and found scheduled downtime for maintenance.

Root Cause

The container registry was temporarily unavailable due to maintenance, and the pods could not access the required images.

Fix/Workaround

• Manually downloaded the images from a secondary registry.
• Temporarily used a local image registry until the primary registry was back online.

Lessons Learned

Ensure that alternate image registries are available in case of downtime.
