Sterling B2Bi in Multizone Environments on IBM Cloud

The ibmc-file-gold-gid StorageClass is not compatible with multizone environments. The following error will happen when you try to provide environment

failed to provision volume with StorageClass "ibmc-file-gold-gid": GID allocation not supported on Multi-Zone Cluster [Multi-Zone Cluster: Zones

You can modify the ansible-ibm-sterling scripts to use the ibmc-file-gold StorageClass, but this will result in the following error:

mkdir: cannot create directory '/ibm/trace/logs': Permission denied
chown: cannot access '/ibm/trace/logs/dbSetup': No such file or directory

This error occurs because the ibmc-file-gold StorageClass requires the container to run as root.

If you need to deploy Sterling B2Bi in a multizone RHOCP, you can adjust the scripts to use ibmc-file-gold by modifying the file:

roles/sb2b_deploy/defaults/main.yaml

and changing the storage_class to ibm-file-gold, then proceed with the deploy. However, the ac, api, and asi pods will not reach the "ready" state and will restart.

To resolve this issue, create a pod to fix the permissions.

apiVersion: v1
kind: Pod
metadata:
  name: fix-permission
  namespace: sterling-b2bi-poc01-app
spec:
  containers:
    - name: fix-permission
      image: 'busybox'
      command: ['sh','-c']
      args: ['chmod 777 /ibm/trace']
      volumeMounts:
        - name: logs
          mountPath: /ibm/trace
  volumes:
    - name: logs
      persistentVolumeClaim:
        claimName: s0-b2bi-logs

Don't forget to change namespace. After ac, api and asi pods become ready, you delete this pod.

In IBM Cloud, the StorageClass of the ReadWriteOnce type, which is requested in the values.yaml of the Helm chart, is ibmc-block-gold.

But when using this storageClass I had permission problems. When changing to the ibmc-file-gold and/or ibmc-file-gold-gid storageClass, I had no problems running C:D in Container, both storageClasses are of the ReadWriteMany type.
