k8s如何使用RDS

作者:互联网

1把RDS的信息做成configmap

apiVersion: v1
kind: ConfigMap
metadata:
  name: nacos-cm
data:
  mysql.host: "阿里云 RDS 内网地址"
  mysql.db.name: "数据库名"
  mysql.port: "数据库端口"
  mysql.user: "数据库用户名"
  mysql.password: "数据库密码"

2在deployment里定义env并引用这些configmap

可提前把这些代码整理好,目的是为了把MYSQL_SERVICE_HOST,MYSQL_SERVICE_DB_NAME,MYSQL_SERVICE_PORT,MYSQL_SERVICE_USER,MYSQL_SERVICE_PASSWORD

这些变量给到后台,让后台使用这些变量连接数据库

env:
  - name: MYSQL_SERVICE_HOST
    valueFrom:
      configMapKeyRef:
        name: nacos-cm
        key: mysql.host               
  - name: MYSQL_SERVICE_DB_NAME
    valueFrom:
      configMapKeyRef:
        name: nacos-cm
        key: mysql.db.name
  - name: MYSQL_SERVICE_PORT
    valueFrom:
      configMapKeyRef:
        name: nacos-cm
        key: mysql.port
  - name: MYSQL_SERVICE_USER
    valueFrom:
      configMapKeyRef:
        name: nacos-cm
        key: mysql.user
  - name: MYSQL_SERVICE_PASSWORD
    valueFrom:
      configMapKeyRef:
        name: nacos-cm
        key: mysql.password

 3后台数据库连接示例代码:

url: jdbc:mysql://${MYSQL_SERVER:127.0.0.1}:${MYSQL_PORT:3306}/${MYSQL_DB_NAME:blogDB}?useUnicode=true&characterEncoding=utf-8&useSSL=false
