At the moment, the application needs two persistent volumes:
- The
/data/
folder whereneo4j
stores its database and - the folder
/nitro-backend/public/uploads
where the backend stores uploads.
As a matter of precaution, the persistent volume claims that setup these volumes live in a separate folder. You don't want to accidently loose all your data in your database by running
kubectl delete -f human-connection/
or do you?
Run the following:
# in folder deployments/
$ kubectl apply -f volumes
persistentvolumeclaim/neo4j-data-claim created
persistentvolumeclaim/uploads-claim created
We tested a couple of options how to do disaster recovery in kubernetes. First, there is the offline backup strategy of the community edition of Neo4J, which you can also run on a local installation. Kubernetes also offers so-called volume snapshots. Changing the reclaim policy of your persistent volumes might be an additional safety measure. Finally, there is also a kubernetes specific disaster recovery tool called Velero.
