HCL Compass persistent volumes

Learn the default vallue settings for persistent volumes in HCL Compass.

By default, HCL Compass helm charts are set to persist the data configuration files to the following mounted folders:
  • hcl-compass data, config, and logs folders.
  • hcl-compass search configuration and data folders.
  • hcl-compass elasticsearch data folder.
The default value settings for the persistent volumes are shown below. You can update these values based on your requirements.

      application:
        enabled: false
      analytics:

You can list persistent volumes (PV) and persistent volume claims (PVC) using kubectl get pv and kubectl get pvc commands. 
$ kubectl get pvc --namespace [namespace_name]
$ kubectl get pv --namespace [namespace_name]
You can use kubectl describe pv [pv-name] and kubectl describe pvc [pvc-name] commands to see more detailed information for each PV and PVC.
Note: Note that the HCL Compass Helm Chart sets the persisten volume by default. If your Kubernetes environment does not provide default StoreageClass, then you must create your own default StorageClass or disable the persistent volume. If you do not, the HCL Compass pods cannot start.
