This page describes how you configure your deployment for persistent storage.
Pre-requisites
Before your helm chart can be configured for persistent storage, the PersistentVolumeClaim resource that you are going to use must exist, and it must exist in the same namespace as where will be deployed.
...
Applying the above yaml using kubectl will create a PersistentVolumeClaim called mz-pvc that you can refer to from the helm chart.
Configuring the Helm Chart
Now that the PersistentVolumentClaim resource exists, it is time to configure the helm chart to use it.
To do this, you set persistence.enabled=true and persistence.existingClaim=mz-pvc and then do a helm upgrade/install.
Runtime
Below is an explanation of how the persistent storage is being used in runtime. All the directories listed can be found within the /opt/mz/persistent directory in your platform, web desktop and EC pod(s).
...
You are free to create whatever additional files/directories under /opt/mz/persistent that your use case may require.
If you, for for example, need to share data between the platform and EC pod(s), you can create a directory /opt/mz/persistent/data and use that to exchange information.

Create the following directories in your persistent volume. This example assumes that the NFS storage example in the Pre-requisites section has been used.
Code Block title Example - Creating directories mkdir /nfs_share/persistent/3pp mkdir /nfs_share/persistent/jni
- Add the 3pp jar files or the jni files into their respective folders.
- Proceed with the installation. will detect the existence of the directories and the files. It will not overwrite or remove the folder.
