1 year ago Changing this has to be evaluated properly:
- EmptyDirs canot be limited in size; this might lead to problems if the caches grow too big. With a PVC, the total amount is limited.
- Depending on the k8s platform, EmptyDirs might incur additional cost or resource limitations compared to PVCs.
- EmptyDirs might have different performance characteristics to PVCS.

Is your feature request related to a problem? Please describe. Right now, the UAPI blob cache is configured as a PVC. However, the UAPI cache will be cleaned/deleted on startup of the client, and it therefor unnecessary to use a PVC for that.
Describe the solution you'd like Use an emptyDir for the blob cache, and make sure the disk space health check is configured correctly, so the component is restarted if the emptyDir grows too big.
