<!-- Answer --> If you’re still seeing chunk errors and DB engine plugin errors only when new pods are created by HPA, even with a single image and baked dependencies, here’s what to check next: - Make sure all new pods are actually running the exact same image (check the image hash/digest with `kubectl describe pod <pod>`). With the default `IfNotPresent` pull policy, nodes may use a cached image if the tag is mutable or if the image wasn’t pulled fresh on every node. For production, always use immutable tags (like a SHA digest) and consider setting `imagePullPolicy: Always` if you suspect image drift. - Compare environment variables, config maps, and secrets between old and new pods (`kubectl get pod <pod> -o yaml`) to ensure there’s no drift or missing values. - Check pod startup logs for errors about missing static assets, missing Python dependencies, or failed mounts. Sometimes, asset or dependency issues only show up in logs during the first few seconds of pod startup. - Look for failed init containers or volume mount errors in new pods. If a mount fails, static assets or configs might not be available at runtime. - Confirm that readiness and liveness probes are working as expected, so pods don’t receive traffic before they’re fully ready. - If you use persistent volumes or shared caches for assets, check for race conditions or stale data that could affect only new pods. The Superset Helm chart ensures all pods (including HPA-created) use the same image, config, and bootstrap/init scripts, so any issues are likely due to image pull policy, image immutability, or runtime environment differences outside the chart itself. If you want a checklist or more targeted troubleshooting, let me know what you find in the logs or pod specs.
