ZotHighErrorRate #

Meaning #

The Zot container registry is returning more than 5% error responses (5xx or 429) for 15 minutes. This indicates elevated failure rates in push/pull operations.

Impact #

Users and CI/CD pipelines experience intermittent failures when pushing or pulling images. Deployments that depend on Zot-hosted images may be delayed.

Diagnosis #

Check Zot pod status:

kubectl get pods -n zot -l app.kubernetes.io/name=zot

Check Zot logs for errors:

kubectl logs -n zot -l app.kubernetes.io/name=zot --tail=100 | grep -i error

Mitigation #

Restart the Zot deployment:

kubectl rollout restart deployment -n zot -l app.kubernetes.io/name=zot

If the issue is rate limiting (429), check if a sync job is running at high frequency and adjust the sync interval in the Zot configuration.
