Pods entered an inconsistent state because the container image failed to pull due to incorrect image tag.

What Happened

Pods started with an image tag that did not exist in the container registry, causing the pods to enter a CrashLoopBackOff state.

Diagnosis Steps

1Checked the pod events and found image pull errors with "Tag not found" messages.
2Verified the image tag in the deployment configuration.

Root Cause

The container image tag specified in the deployment was incorrect or missing from the container registry.

Fix/Workaround

• Corrected the image tag in the deployment configuration to point to an existing image.
• Redeployed the application.

Lessons Learned

Always verify image tags before deploying and ensure the image is available in the registry.

How to Avoid

1Use CI/CD pipelines to automatically verify image availability before deployment.
2Enable image pull retries for transient network issues.
