Volumes
At the moment, the application needs two persistent volumes:
The
/data/
folder whereneo4j
stores its database andthe 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/
, do you?
Create Persistent Volume Claims
Run the following:
# in folder deployments/
$ kubectl apply -f volumes
persistentvolumeclaim/neo4j-data-claim created
persistentvolumeclaim/uploads-claim created
Change Reclaim Policy
We recommend to change the ReclaimPolicy
, so if you delete the persistent volume claims, the associated volumes will be released, not deleted:
$ kubectl --namespace=human-connection get pv
NAME CAPACITY ACCESS MODES RECLAIM POLICY STATUS CLAIM STORAGECLASS REASON AGE
pvc-bd02a715-66d0-11e9-be52-ba9c337f4551 1Gi RWO Delete Bound human-connection/neo4j-data-claim do-block-storage 4m24s
pvc-bd208086-66d0-11e9-be52-ba9c337f4551 2Gi RWO Delete Bound human-connection/uploads-claim do-block-storage 4m12s
Get the volume id from above, then change ReclaimPolicy
with:
kubectl patch pv <VOLUME-ID> -p '{"spec":{"persistentVolumeReclaimPolicy":"Retain"}}'
# in the above example
kubectl patch pv pvc-bd02a715-66d0-11e9-be52-ba9c337f4551 -p '{"spec":{"persistentVolumeReclaimPolicy":"Retain"}}'
kubectl patch pv pvc-bd208086-66d0-11e9-be52-ba9c337f4551 -p '{"spec":{"persistentVolumeReclaimPolicy":"Retain"}}'
