k8s 部署mysql

1.编辑 mysql.yaml

(deployment, service)

apiVersion: apps/v1kind: Deploymentmetadata: name: mysql-rcspec: replicas: 1 selector: matchLabels: app1: mysql template: metadata: labels: app1: mysql spec: #添加标签调度 #nodeSelector: # app1: mysql #根据 NodeName 调度 nodeName: kube01 containers: - name: mysql image: mysql:5.7 imagePullPolicy: IfNotPresent ports: - containerPort: 3306 env: - name: ALLOW_EMPTY_PASSWORD value: "yes" - name: MYSQL_ROOT_USER value: root - name: MYSQL_ROOT_PASSWORD value: Mrtoo902li - name: MYSQL_CHARACTER_SET value: utf8 - name: MYSQL_COLLATE value: utf8_general_ci - name: MYSQL_DATABASE value: face_privatization volumeMounts: - name: mysql mountPath: /var/lib/mysql volumes: - name: mysql hostPath: path: /root/test/data2/mysql restartPolicy: Always---apiVersion: v1kind: Servicemetadata: name: mysql-svc labels: app1: mysqlspec: type: NodePort ports: - port: 3306 protocol: TCP targetPort: 3306 name: nodePort: 32306 selector: app1: mysql

说明

挂载的卷 path: /root/test/data2/mysql 不用配置数据文件，启动之后，数据就有数据了

2.创建

kubectl apply -f mysql.yaml

3.查看pod

kubectl get pods -o widemysql-rc-6f74fc486-l52cv 1/1 Running 0 11s 10.211.65.17 kube01

4.查看service

kubectl get svc

5.测试mysql连接

kubectl exec -it mysql-rc-6f74fc486-l52cv -- /bin/bash#测试连接mysql -u root -p'Mrtoo902li' -h 192.20.5.75 -P 32306mysql: [Warning] Using a password on the command line interface can be insecure.Welcome to the MySQL monitor.
