Hey folks, we're looking into why ClickHouse pods are not coming online with the correct CPU/Memory requests. We deployed with the Helm chart (v0.59.0). On the 0-0-0 and 0-1-0 pods, we see this (which is correct):
Copy code
Limits:
      cpu:     4
      memory:  16Gi
    Requests:
      cpu:        3
      memory:     12Gi
However, on other pods (such as 1-0-0 and 1-1-0), we see this (notice wrong values, and no limits set):
Copy code
Requests:
      cpu:        100m
      memory:     200Mi
Any idea what would be causing that? We've set the following in our values.yaml:
Copy code
clickhouse:
  resources:
    requests:
      cpu: 3000m
      memory: 12Gi
    limits:
      cpu: 4000m
      memory: 16Gi
This is an issue, because the 1-0-0 and 1-1-0 pods are tripping our CPU/Memory alarms with alerts of like "Pod is using 3500% CPU" etc.
Reinstalled using chart v0.60.0, and it seems to be resolved. Will keep an eye on this and report back if it happens again.
