K8S部署MySQL

创建mysql-deployment.yaml
先拉取镜像

docker pull registry.cn-hangzhou.aliyuncs.com/acs-sample/mysql:5.7

apiVersion: apps/v1
kind: Deployment
metadata:
  name: mysql-deployment
spec:
  replicas: 1
  selector:
    matchLabels:
      app: mysql
  template:
    metadata:
      labels:
        app: mysql
    spec:
      containers:
      - name: mysql
        image: registry.cn-hangzhou.aliyuncs.com/acs-sample/mysql:5.7
        ports:
        - containerPort: 3306  # MySQL 默认端口
        env:
        - name: MYSQL_ROOT_PASSWORD
          value: "123456"  # 设置 MySQL root 密码

创建mysql-service.yaml

apiVersion: v1
kind: Service
metadata:
  name: mysql-service
spec:
  selector:
    app: mysql
  ports:
    - port: 3306
      targetPort: 3306
      nodePort: 30306  # 这里指定暴露对外的NodePort
  type: NodePort

kubectl apply -f mysql-deployment.yaml
kubectl apply -f mysql-service.yaml

查看

kubectl get pods --namespace default
kubectl get services --namespace default

然后进入容器
kubectl get pods -o wide -A
kubectl exec -it mysql-deployment-6674c97b46-hm64c /bin/bash

mysql -u root -p
输入密码，文字的yaml密码是123456
GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY '123456' WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
GRANT SELECT,DELETE,UPDATE,CREATE,DROP ON *.* to root@"%" IDENTIFIED BY "123456";
GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost.localdomain' IDENTIFIED BY '123456' WITH GRANT OPTION;
