Vertical Scaling for MinIO

Prerequisites

• A functional Kubernetes cluster (v1.21+ recommended)
• kubectl v1.21+ installed and configured with cluster access
• KubeBlocks installed (installation guide)
• MinIO Add-on enabled:

  helm install minio kubeblocks/minio --version 1.1.0-alpha.0 -n kb-system
  

• A namespace for the cluster (examples use demo):

  kubectl create ns demo
  

Scale Up Resources

Increase CPU and memory for all MinIO pods:

kubectl apply -f - <<EOF
apiVersion: operations.kubeblocks.io/v1alpha1
kind: OpsRequest
metadata:
  name: minio-vscale
  namespace: demo
spec:
  clusterName: minio-cluster
  type: VerticalScaling
  verticalScaling:
    - componentName: minio
      requests:
        cpu: "2"
        memory: "2Gi"
      limits:
        cpu: "2"
        memory: "2Gi"
EOF

Monitor progress:

kubectl get opsrequest minio-vscale -n demo -w

NAME           TYPE              CLUSTER         STATUS    PROGRESS   AGE
minio-vscale   VerticalScaling   minio-cluster   Succeed   2/2        90s

Cleanup

kubectl delete opsrequest minio-vscale -n demo --ignore-not-found
