Create a Storage Class

During installation, the Fluentd logging and Cluster Wide Controller (CWC) must be able to access a persistent storage (storageClass). This is necessary for storing log files and Qkview collection process. Users must create a storageClass and refer in the SPKInstance CR, see Install BIG-IP Next for Kubernetes.

1. Verify if a storageClass is available.

   kubectl get storageclass
   

   If the storageClass is available and set to default type, you no need to specify in the SPKInstance CR during BIG-IP Next for Kubernetes installation process. Otherwise, you must refer the storageClass name in the SPKInstance CR, see Install BIG-IP Next for Kubernetes.

2. If you do not have a storageClass, see Storage Classes to create.

3. Once the storageClass is created successfully, refer the newly storageClass name in the SPKInstance CR, see Install BIG-IP Next for Kubernetes.

   Example Storage Class refernce for CWC:

   spec:
   cwc:
       persistence:
       enabled: false
       accessMode:
       - ReadWriteOnce
       storageClass: storageclass-cwc
       size: 3Gi  
   

   Example Storage Class refernce for Fluentd:

   spec:
   fluentd:
       persistence:
       enabled: false
       accessMode:
       - ReadWriteOnce
       storageClass: storageclass-fluentd
       size: 3Gi
