apiVersion: v1
kind: ConfigMap

  name: mysql-initdb-config
data:
  init.sql: |
    CREATE DATABASE IF NOT EXISTS mydb;
---
apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: my-mysql-stateful-set
  namespace: my-test-app
spec:
  replicas: 1
  selector:
    matchLabels:
      app: my-mysql
  serviceName: my-mysql
  template:
    metadata:
      labels:
        app: my-mysql
    spec:
      containers:
      - name: mysql
        image: mysql:8.3
        env:
        - name: MYSQL_ROOT_PASSWORD
          value: root
        ports:
        - containerPort: 3306
          name: mysql
        volumeMounts:
        - name: mysql-persistent-storage
          mountPath: /var/lib/mysql
        - name: mysql-initdb
          mountPath: /docker-entrypoint-initdb.d
      volumes:
        - name: mysql-initdb
          configMap:
            name: mysql-initdb-config
  volumeClaimTemplates:
  - metadata:

    - protocol: TCP
      port: 3306
      targetPort: 3306

2. Enable ingress-controller in minikube by minikube addons enable ingress
3. Have gone through the below solution
   3.1 official solution: https://minikube.sigs.k8s.io/docs/tutorials/nginx_tcp_udp_ingress/
   3.2 Solutions provided by the commentators
   Minikube Ingress TCP Services Not Forwarding Traffic #2840
4. Run minikube tunnel to enable the access
5. Connect mysql through localhost:3306
