映射值错误：无法查明问题根源

Question

这是我的 mysql-deployment.yaml，我试图让它在 kubernetes 上运行，但我收到错误，我已经在我的部署.yml 下面提到了错误

apiVersion: v1
kind: Service
metadata:
  name: mysql
  labels:
    app: mysql
    tier: database
spec:
  ports:
    - port: 3306
      targetPort: 3306
  selector:
    app: mysql
    tier: database
  clusterIP: None

apiVersion: v1
kind: PersistentVolumeClaim
metadata:

  labels:

      app: mysql

    metadata: 
      labels:
        apps: mysql
        tier: database
    spec:
      containers:
      - image: mysql:5.7
        name: mysql
        env:
        - name: MYSQL_ROOT_PASSWORD
          valueFrom:
            secretKeyRef:
              name: db-root-credentials
              key: password
        - name: MYSQL_USER
          valueFrom:
            secretKeyRef::
              name: db-credentials
              key: username
        - name: MYSQL_PASSWORD
          valueFrom:
            secretkeyRef:
              name: db-credentials
              key: password
        - name: MYSQL_DATABASE
          valueFrom:
            configMapKeyRef:
              name: dbbuddyto_mstr_local
              key: name
      ports:
        - containerPort: 3306
          name: mysql
      volumeMounts:
          - name: mysql-persistent-storage
            mountPath: /var/lib/mysql
      volumes:
          - name: mysql-persistent-storage
            PersistentVolumeClaim:
              claimName: mysql-pv-claim

我收到两个错误： 解析 mysql-deployment.yml 时出错：将 YAML 转换为 JSON 时出错：yaml：第 24 行：此上下文中不允许映射值

第二个错误是

来自服务器的错误（BadRequest）：创建“mysql-deployment.yml”时出错：版本“v1”中的 PersistentVolumeClaim 无法作为 PersistentVolumeClaim 处理：严格解码错误：未知字段“spec.accessMode”

我正在尝试为 Angular、Spring 和 mysql 构建 Kubernetes 部署。 上述错误是我目前面临的错误。

您的 PVC 问题是一个拼写错误。它需要是 spec.accessModes，你错过了最后的 s。

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: mysql-pv-claim
  labels:
    app: mysql
    tier: database
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi

编辑：
