Sample  Storage Class and Volume for HCL WebSphere Portal 9.5 Containers

Learn how to  set storage class and volume using a sample storage class and volume  scripts  for   HCL WebSphere Portal 9.5 CF_171 and higher container releases deployed to Amazon Elastic Container Service (EKS) or Red Hat OpenShift environment.

HCL recommends a separate storage class and volume be set for production, especially if we have more than one project in the Kubernetes (Amazon EKS or OpenShift) environment. This is a good practice because it prevents projects from stepping on one another's storage volumes.

Follow these steps to create a new persistent volume and storage class, in either Amazon EKS or OpenShift.

1. Use and save the following as your storage class file:

   kind:  StorageClass  
                       apiVersion: storage.k8s.io/v1  
                       metadata:  
                       name: dx-deploy-stg  
                       provisioner: kubernetes.io/no-provisioner  
                       reclaimPolicy: Retain  
                       volumeBindingMode:  WaitForFirstConsumer  

2. Use and save the following as your storage volume file:

   kind:  PersistentVolume  
                       apiVersion: v1  
                       metadata:  
                       name: wp-profile-volume  
                       spec:  
                       capacity:  
                       storage: 100Gi     
                       nfs:  
                       server: your_nfs_server.com  
                       path: /exports/volume_name  
                       accessModes:  
                       -  ReadWriteMany  
                       persistentVolumeReclaimPolicy: Retain  
                       storageClassName: dx-deploy-stg  
                       mountOptions:  
                       - hard  
                       -  nfsvers=4.1  
                       -  rsize=8388608  
                       -  wsize=8388608  
                       -  timeo=600  
                       -  retrans=2  
                       -  noresvport  
                       volumeMode: Filesystem

3. Copy both files to your local filesystem.

4. Change at least the server and path in your sample volume .yaml  file to an appropriate NFS server and volume.

5. To create the storage class, run the following command:

   kubectl  apply -f  subclass.yaml

6. To create the storage volume, run the following command:

   kubectl  apply -f  SampleZVolume.yaml

7. Continue with deployment.

Note: In these examples NFS volumes have been used. The following sample  yaml  can be used to create the volume in  Amazon EKS OpenShift with the corrected values for:  

nfs:  
     
                server:  your_nfs_server.com  
     
                path: /exports/volume_name
