K8s: Create PVs without nodeAffinity

Here's how to create persistent volumes in Kubernetes without having to set nodeAffinity.

1 min read

If you're looking to create persistent volumes in Kubernetes without setting nodeAffinity, setup your PV config like this:

---
apiVersion: v1
kind: PersistentVolume
metadata:
  name: 
  labels:
    type: local
spec:
  capacity:
    storage: 10Gi
  accessModes:
  - ReadWriteOnce
  persistentVolumeReclaimPolicy: Retain
  storageClassName: local-path
  hostPath:
    path: /opt/data/

Note how we are using the labels key under metadata as well as changing path under spec to hostPath.

Hope this helps!  I was stuck on it for a while.  This is useful for single node K8s setups where you are only storing data locally (on the one host).
