How to set volume name on Helm install in Kubernetes DO-block storage

Posted on August 28, 2020

Hello,

I am using Helm to manage installing new services in Kubernetes. I am using DO-block storage, and when I install a new site I automatically create a RWO volume to my pod to attach to.

I cannot however for the life of my understand how I can name my volumes. As I have atleast 50+ websites, it is nice to have a naming convention on them. Yes, I know that I see which services they are attached to etc, but reading the name “pvc-fadf4420-1f77-4fasc-8gg9b-df333eee75f49” in my Digital Ocean admin panel does not tell me much. I would like to name the volume “URL-pvc” for now. Is this possible to specify in the Helm chart?

@jehansstorvik The name is derived from the value of the name key within metadata. For example,

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
 name: name-of-my-pvc
spec:
 storageClassName: manual
 selector:
 accessModes:
   - ReadWriteOnce
 resources:
   requests:
     storage: 20Gi

In the above, one can change the name-of-my-pvc to any suitable name for your particular use case. Now, you should be able to list this resource by doing the following:
