@CaRRotOne hi, did you click User Logs a not-short period after pod completed? Dashboard retrieves pod logs from apiserver and it will no longer exists once rootfs of container was reclaimed.

@SimonCqk the User Logs doesn't show anything neither pod running nor pod completed.

@CaRRotOne as we offline discussed, it is caused by pods/log rbac configuration and has been fixed.
