kind: Deployment
metadata:
  labels:
    app: mysql
  name: mysql
  namespace: moonfdd
spec:
  replicas: 1
  selector:
    matchLabels:
      app: mysql
  template:
    metadata:
      labels:
        app: mysql
    spec:
      containers:
        - env:
            - name: MYSQL_ROOT_PASSWORD
              value: 'moonfdd'
          image: 'mysql:8.0'
          name: mysql
          volumeMounts:
            - mountPath: /var/lib/mysql
              name: volv
      volumes:
        - hostPath:
            path: /root/k8s/moonfdd/mysql/var/lib/mysql
            type: DirectoryOrCreate
          name: volv
