CSI: How to use a Private Repository for PowerFlex Storage Data Client container running on Red Hat Core operating system nodes

More steps to enable private repository usage when using the SDC documentation: https://hub.docker.com/r/dellemc/sdc

To enable the use a private repository rather than the default (ftp.emc.com), you must do the following:

1. Create a secret, sdc-repo-secret.yaml to contain the credentials for the private repo.

   To generate the base64 encoding of a credential, replace <credential> the username and then the password:

   echo -n <credential>| base64 -i

   Secret "yaml" sample to use:

   apiVersion: v1
   kind: Secret
   metadata:
     name: sdc-repo-creds
     namespace: vxflexos
   type: Opaque
   data:
     # set username to the base64 encoded username, sdc default is
     username: <username in base64>
     # set password to the base64 encoded password, sdc default is
     password: <password in base64>

   After the helm/sdc-repo-secret.yaml is updated, create the secret:

   kubectl create -f sdc-repo-secret.yaml

2. Edit helm/csi-vxflexos/templates/node.yaml to use your secret created in step 1.

   Under the initContainers.env and sdc-monitor.env sections, add:

   - name: REPO_ADDRESS
     value: <url to private repo>
   - name: REPO_USER
     valueFrom:
       secretKeyRef:
         name: sdc-repo-creds
         key: username
   - name: REPO_PASSWORD
     valueFrom:
       secretKeyRef:
         name: sdc-repo-creds
         key: password

   Under initContainers.volumeMounts, add the following:

   - name: sdc-config
     mountPath: /config

   Under containers.volumes add:

   - name: sdc-config
     hostPath:
       Path: /var/sio-config
       type: DirectoryOrCreate

3. On the worker nodes, create the directory: "/var/sio-config" and inside, place all config files that the SDC service requires to access your private repo using sftp. For example, place the user_private_rsa_key file inside. See the SDC Container Document link.

4. Continue the driver installation.
