已完成以下步骤：- 1. 我创建了一个持久卷声明并在我的 mysql 部署中使用它 2. 在配置中创建了一个通用密钥并将其设置在 env 中以进行部署

        env:
      - name: MYSQL_ROOT_PASSWORD
        valueFrom:
            secretKeyRef:
              name: my-db-pass
              key: password

3.使用以下cmd连接到我的实例mysql --host= --user=root -p 之后发生以下错误-

ERROR 1045 (28000): Access denied for user 'root'@'10.128.0.18' (using password: YES)

mysql 的 kubectl pod 日志是 -

还提供了用于 mysql-deployment 的 yaml 文件

apiVersion: apps/v1
kind: Deployment
metadata:
  name: mysql
  labels:
    app: mysql
spec:
  replicas: 1
  selector:
    matchLabels:
      app: mysql
  template:
    metadata:
      labels:
        app: mysql
    spec:
      containers:
      - name: mysql
        image: mysql:8
        args:
          - "--default-authentication-plugin=mysql_native_password"
        env:
          - name: MYSQL_ROOT_PASSWORD
            valueFrom:
                secretKeyRef:
                  name: my-db-pass
                  key: password
        ports:
          - containerPort: 3306
            name: mysql
        volumeMounts:
          - name: mysql-persistent-storage
            mountPath: /var/lib/mysql
      volumes:
        - name: mysql-persistent-storage
          persistentVolumeClaim:
