        persistentVolumeClaim:
        claimName: mysql-nfs

but It's throwing this error when I Try to run the yaml file:

error validating "nfs-mysql.yaml": error validating data: [unknown object type "nil" in Deployment.spec.selector.matchLabels.strategy, ValidationError(Deployment.spec): unknown field "spec" in io.k8s.api.apps.v1.DeploymentSpec]; if you choose to ignore these errors, turn validation off with --validate=false

I don't understand the error can someone help me with this error?

There us that your YAML file having the issue with strategy

spec:
  selector:
  matchLabels:
    app: mysql-wordpress
    product: mysql
    strategy:
    type: Recreate
  template:
  metadata:

it should be like

strategy:
  type: RollingUpdate

it should not be part the selector like you have mentioned so there is indentation issue with that, you can use below on for ref

spec:
  replicas: 4
  selector:
    matchLabels:
      app: nginx
  minReadySeconds: 5
  strategy:
    type: RollingUpdate
    rollingUpdate:
      maxSurge: 1
      maxUnavailable: 1

even your selector having the issue so make you follow the proper indentation path in YAML.
