Checklist

For operator, please complete the following checklist:

• run make generate to generate the code.
• run golangci-lint run to check the code style.
• run make test to run UT.
• run make manifests to update the yaml files of CRD.

For helm chart, please complete the following checklist:

• make sure you have updated the values.yaml
  file of starrocks chart.
• In scripts directory, run bash create-parent-chart-values.sh to update the values.yaml file of the parent
  chart( kube-starrocks chart).

-----Test Plan----

1. helm lint

2. helm template with settings on/off, and see the diff of helm template starrocks .
   
   

3. apply the new StarRocksCluster yaml

----Revision 2 Test Plan-------

1. turn on be/fe profiling, no difference compared with revision 1;

2. Add starrocksBeSpec.capabilities in values to confirm it's merged correctly

  capabilities:
    add:
      - PERFMON
      - SYS_PTRACE
    drop:
      - SYS_ADMIN

See output as below

----revision 4 test plan-----
switch enabledBe/enabledCn: true/false, plus with additional capabilities

  capabilities:
    add:
      - PERFMON
      - SYS_PTRACE
    drop:
      - SYS_ADMIN

The diff of helm template is shown as below:

Dry-run

k apply -n xxxx -f ./issue-423.on.r3.yaml --dry-run="server"
configmap/kube-starrocks-cn-cm created (server dry run)
configmap/kube-starrocks-fe-cm created (server dry run)
starrockscluster.starrocks.com/kube-starrocks created (server dry run)

I would like to ask, what is your screenshot tool?

I would like to ask, what is your screenshot tool?

It's the Compare Files feature in Intellij. If you want to re-produce it, here are the full steps:

cd starrocks-kubernetes-operator/helm-charts/charts/kube-starrocks/charts/starrocks
# 1. do nothing to render default yaml
helm template starrocks . > ./issue-423.off.yaml

# 2. update values.yaml to turn on profiling
helm template starrocks . > ./issue-423.on.yaml

# 3. compare the two files ./issue-423.off.yaml and /issue-423.on.yaml
