I have a Neo4j service, but before the deployment starts up, I need to pre-fill it with data (about 2GB of data). Currently, I wrote a Kubernetes `Job` to transform the data from a CSV and format it for the database using the `neo4j-admin` tool. It saves the formatted data to a *persistent volume*. After waiting for the job to complete, I mount the volume in the Neo4j container and the container is effectively read-only on this data for the rest of its life. 

**Is there a better way to do this more automatically?**

I don't want to have to wait for the job to complete to run another command to create the Neo4j deployment. I looked into initContainers, but that isn't suitable because I don't want to redo the data filling when a pod is re-created. I just want subsequent pods to read from the same persistent volume. Is there a way to wait for the job to complete first?
