1、安装
2、完整卸载 mysql（pod/deployment/service/pvc）

1、安装

1.1、环境

docker 部署 minikube,minikube 中部署 mysql
Mac，注意芯片类型和 workbench 版本适配（workbench最新版 8.0.40，对于image mysql:version, version 的值 M2 版本 8.0.30, Intel 芯片 8.0）

1.2、workbench 崩溃问题

在 MySQL Workbench 中，点击 Help 菜单，然后选择 About MySQL Workbench 查看版本

kubectl exec -it – mysql --version 查看k8s 中 mysql 版本

1.1、deployment.yaml 文件

apiVersion: apps/v1
kind: Deployment
metadata:
  name: mysql-deployment
  labels:
    app: mysql
spec:
  replicas: 1
  selector:
    matchLabels:
      app: mysql
  template:
    metadata:
      labels:
        app: mysql
    spec:
      containers:
      - name: mysql
        image: mysql:8.0  # M2 版本 8.0.30,目前最新 workbench 最高到 8  #非 arm 架构芯片可以写 image: mysql:8.0
        env:
        - name: MYSQL_ROOT_PASSWORD
          value: rootadmin  # 设置 root 用户密码
        ports:
        - containerPort: 3306
        volumeMounts:
        - name: mysql-storage
          mountPath: /var/lib/mysql  # MySQL 数据存储路径
      volumes:
      - name: mysql-storage
        persistentVolumeClaim:
          claimName: mysql-pvc  # 使用 PVC
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: mysql-pvc
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi  # 请求的存储大小
  storageClassName: standard  # 确保与您的 PV 的存储类匹配
---
apiVersion: v1
kind: Service
metadata:
  name: mysql-service
spec:
  type: NodePort  # 设置为 NodePort 类型
  selector:
    app: mysql  # 选择与 Deployment 中相同的标签
  ports:
    - port: 3306  # Service 的端口
      targetPort: 3306  # Pod 中的端口
      nodePort: 30002  # 自定义 NodePort（可选，范围是 30000-32767）

1.2、运行

kubectl apply -f mysql-deployment.yaml

1.3、启动隧道，从宿主机直接访问 k8s 中的mysql

minikube get services
minikube service mysql-service

2、完整卸载 mysql（pod/deployment/service/pvc）
