operator helm upgrade from 4.5.8 to 5.0.3 - cniackz/public GitHub Wiki

• You can get Helm Release from: https://github.com/minio/operator/tree/master/helm-releases

1. In a cluster, installed Operator version 4.5.8 with Helm:

helm install \
     --namespace minio-operator \
     --create-namespace \
     minio-operator ./operator-4.5.8.tgz

$ k get pods minio-operator-5bccb66546-6792k  -n minio-operator -o yaml | yq '.spec.containers[0].image'
minio/operator:v4.5.8

2. Deployed a tenant with Helm:

helm install \
  --namespace tenant-ns \
  --create-namespace \
  tenant-ns ./tenant-4.5.8.tgz

$ k get pods -n tenant-ns
NAME              READY   STATUS    RESTARTS   AGE
minio1-pool-0-0   1/1     Running   0          108s
minio1-pool-0-1   1/1     Running   0          108s
minio1-pool-0-2   1/1     Running   0          108s
minio1-pool-0-3   1/1     Running   0          107s

3. Put some Objects:

4. Upgraded Operator:

$ helm upgrade \
     --namespace minio-operator \
     minio-operator ./operator-5.0.3.tgz

5. Restarted Operator Pods

6. Waited some time for the upgrade to go thru.

7. Get the Objects after Tenant initialized again:

$ mc ls myminio/testing --insecure

8. Notice you have now two container per node, meaning sidecar is running:

$ k get pods -n tenant-ns
NAME              READY   STATUS    RESTARTS   AGE
minio1-pool-0-0   2/2     Running   0          3m25s
minio1-pool-0-1   2/2     Running   0          3m41s
minio1-pool-0-2   2/2     Running   0          3m47s
minio1-pool-0-3   2/2     Running   0          3m54s
