Deploy Multiple Clusters HOWTO

If you have deployed a StarRocks cluster by YAML manifests, you can write a new StarRocksCluster CR YAML to deploy another StarRocks cluster.

We have split the kube-starrocks chart into two subcharts: operator and starrocks. Installing kube-starrocks is equivalent to installing both operator and starrocks subcharts, and uninstalling kube-starrocks is equivalent to uninstalling both operator and starrocks subcharts.

If you have deployed a StarRocks cluster by operator + starrocks helm chart, you can deploy another StarRocks cluster by the starrocks helm chart.

If you have deployed a StarRocks cluster by kube-starrocks helm chart, you have two ways to deploy another StarRocks cluster.

  1. Deploy another StarRocks cluster by starrocks helm chart.
  2. Deploy another StarRocks cluster by kube-starrocks Helm chart.

This document will guide you through the process of deploying multiple StarRocks clusters by kube-starrocks helm chart.

Deploy another StarRocks cluster by kube-starrocks Helm chart

By default, the operator will watch all namespaces. If you want to deploy another StarRocks cluster by kube-starrocks, you should limit each operator to watch a specific namespace.

operator:
  starrocksOperator:
    watchNamespace: "your-namespace"

you can also add --set operator.starrocksOperator.watchNamespace="your-namespace" to the helm command which has higher priority.

So, the steps to deploy multiple StarRocks clusters by kube-starrocks are:

  1. update values.yaml file of the first deployed StarRocks cluster to limit the operator to watch a specific namespace.
  2. upgrade the first StarRocks cluster.
  3. install the second StarRocks cluster by the same kube-starrocks chart, and do not forget to specify the namespace.
