用kubernetes访问mysql：用户root拒绝访问

Question

我有两个豆荚

• MySQL的
• .jar文件（适用于Java的微服务服务器）

这是mysql .yaml文件

apiVersion: v1
kind: Pod
metadata:
  name: mysql
  labels: 
    name: mysql
spec: 
  containers:
    - resources:
        limits :
          cpu: 0.5
      image: mysql
      name: mysql
      env:
        - name: MYSQL_ROOT_PASSWORD
          # change this
          value: pass
      ports: 
        - containerPort: 3306
          name: mysql
      volumeMounts:
        - name: mysqlkuber
          mountPath: /var/lib/mysql
          readOnly: false
  volumes:
    - name: mysqlkuber
      hostPath:
        path: /home/adicipta/mysqlkuber

我用ip 10.0.0.67:3306公开了Pod mysql服务

.jar文件窗格与此命令一起运行

 sudo ./kubectl run lingga --image=msf4j

我得到这个错误

在.jar文件中，我具有已经将ip设置为（10.0.0.67:3306）的bean.xml。

我只是不明白为什么它不起作用

也许有人可以帮我解决

我将kubernetes与docker容器一起使用

只需在数据源代码处设置密码

此数据源代码在我的.jar文件中

<property name="username" value="root" />
<property name="password" value="pass" />

这取决于您的数据源的外观。
