I have a yml file where I create a pvc on my provider (digital ocean)
apiVersion: v1 kind: PersistentVolumeClaim metadata: name: test-pvc namespace: test spec: accessModes: - ReadWriteOnce resources: requests: storage: 10Gi storageClassName: do-block-storage I am also using a helm chart and want to be able to point to the already created pvc How can I do this? This helm chart is deployed after the PVC is already created/deployed
master: persistence: enabled: true ## mariadb data Persistent Volume Storage Class ## If defined, storageClassName: <storageClass> ## If set to "-", storageClassName: "", which disables dynamic provisioning ## If undefined (the default) or set to null, no storageClassName spec is ## set, choosing the default provisioner. (gp2 on AWS, standard on ## GKE, AWS & OpenStack) ## # storageClass: "-" accessMode: ReadWriteOnce size: 10Gi 1 Answer
To mount your PVC in your helm chart, do this:
- Disable persistence volume creation in helm chart
master: persistence: enabled: false #Setting it to false - Modify your deployment yaml, its located in templates folder of your helm chart. Point your Pod to mount your own PVC.
Something like this:
apiVersion: v1 kind: Pod metadata: name: task-pv-pod spec: volumes: - name: task-pv-storage persistentVolumeClaim: claimName: test-pvc # pointing to existing test-pvc containers: - name: task-pv-container image: nginx ports: - containerPort: 80 name: "http-server" volumeMounts: - mountPath: "/usr/share/nginx/html" name: task-pv-storage Update:
Specifically in your case, you can specify your pvc name against existingClaim parameter in values.yaml, it will be picked up by your deployment.
