error:error parsing yaml , converting YAML to JSON: yaml: line 20: did not find expected '-' indicator Kubernetes

Question

大家好我正在尝试在 Kubernetes 中部署运行s mongoDB 的 nodejs 应用程序。为了实现这一点，我创建了一个名为 k8s 的文件夹，在该文件夹中我有 2 个文件 - deployment_nodejs.yaml 和 deployment_mongo.yaml。在运行命令 kubectl apply -f k8s 之后。我成功创建了 'deployment_nodejs.yaml'，但 部署另一个失败 。错误说明如下：'error: error parsing k8s/deployment_mongo.yaml: error converting YAML to JSON: yaml: line 20: did not find expected '-'指示器'。我意识到错误可能是 ports 命令，尽管我不明白为什么，因为在我看来我做错了什么。希望你能帮我修复这个错误。

deployment_mongo.yaml 文件的代码：

kind: PersistentVolumeClaim
metadata:
  name: mongo-pvc 
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 256Mi

---
apiVersion: v1
kind: Service
metadata:
  name: mongo
spec:
  selector:
    app: mongo
  ports:
  - port: 27017
    targetPort: 27017
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: mongo
spec: 
  selector: 
    matchLabels: 
      app: mongo
  template:
    metadata:
      labels:
        app: mongo
    specs:
      containers:
        - name: mongo
          image: 3.6.23-xenial
          ports:
            - containerPort: 27017
          volumeMounts: 
            - name: storage
            mountPath: /data/db
      volumes:
        - name: storage
        PersistentVolumeClaim:
          claimName: mongo-pvc

Answer 1

第 20 行 spce:，而不是 spec:

在部署中，将specs:更改为spec:

Answer 2

已尝试根据给定的 YAML 生成资源，以下是发现的问题。 api-version 未在第一行提及，volumes 和 volumeMounts 在 Deployment Yaml 中未正确缩进。 PersistentVolumeClaim（大写的 P 应该是 persistentVolumeClaim），claimName 没有缩进。修复它们或使用下面的清单，您应该可以开始了。

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: mongo-pvc 
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 256Mi

---
apiVersion: v1
kind: Service
metadata:
  name: mongo
spec:
  selector:
    app: mongo
  ports:
  - port: 27017
    targetPort: 27017
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: mongo
spec: 
  selector: 
    matchLabels: 
      app: mongo
  template:
    metadata:
      labels:
        app: mongo
    spec:
      containers:
        - name: mongo
          image: 3.6.23-xenial
          ports:
            - containerPort: 27017
          volumeMounts: 
            - name: storage
              mountPath: /data/db
      volumes:
        - name: storage
          persistentVolumeClaim:
            claimName: mongo-pvc
