映射值錯誤。 無法弄清楚問題出在哪里

Question

這是我的 mysql-deployment.yaml 我試圖讓它在 kube.netes 上運行但是我收到錯誤我在我的 deployment.yml 下面提到了錯誤

apiVersion: v1

          valueFrom:
            secretKeyRef:
              name: db-root-credentials
              key: password
        - name: MYSQL_USER
          valueFrom:
            secretKeyRef::
              name: db-credentials
              key: username
        - name: MYSQL_PASSWORD
          valueFrom:
            secretkeyRef:

              key: password

          valueFrom:
            configMapKeyRef:

              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

我收到兩個錯誤： error parsing mysql-deployment.yml: error converting YAML to JSON: yaml: line 24: mapping values are not allowed in this context

第二個錯誤是

Error from server (BadRequest): error when creating "mysql-deployment.yml": PersistentVolumeClaim in version "v1" cannot be handled as a PersistentVolumeClaim: strict decoding error: unknown field "spec.accessMode"

我正在嘗試為 angular、spring 和 mysql 構建一個 Kube.netes 部署。提到的錯誤是我目前面臨的錯誤。

Answer 1

您的 PVC 問題是錯字。 它需要是spec.accessModes ，你最后錯過了 s 。

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

編輯：

apiVersion: v1
kind: Service
metadata:
  name: mysql
  labels:
    app: mysql
    tier: database
spec:
  ports:
    - port: 3306
      targetPort: 3306
  selector:
    app: mysql
    tier: database

          PersistentVolumeClaim:
            claimName: mysql-pv-claim

Answer 2

除了accessModes的拼寫錯誤外， ports和volumes的縮進不夠。 它們都是容器的元素。 還修復了secretKeyRef錯字：

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:
  name: mysql-pv-claim
  labels:
    app: mysql
    tier: database
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: mysql
  labels:
    app: mysql
    tier: database
spec:
  selector:
    matchLabels:
      app: mysql
      tier: database
  strategy:
    type: Recreate
  template:
    metadata:
      labels:
        app: 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

更新：

還修復了labels以匹配matchLabels 、 persistentVolumeClaim中的大小寫錯誤和 configMap dbbuddyto-mstr-local名稱。 這個很重要。 _是不允許的。

在 minikube 上現在沒有錯誤。
