spring-boot - 在 Kubernetes 中验证部署错误

Question

我尝试在 Kubernetes 集群中部署带有 MySQL 数据库的 producer-service 应用程序。当我尝试部署 producer app 时，出现了以下验证错误。

error: error validating "producer-deployment.yml": error validating data: apiVersion not set; if you choose to ignore these errors, turn validation off with --validate=false

生产者部署.yml

apiVerion: v1

    port: 9090
    targetPort: 9090
    protocol: TCP
  selector:
    app: producer-app
  type: NodePort

                key: host
            - name: DB_NAME
              valueFrom:
               configMapKeyRef:
                name: db-config
                key: name
            - name: DB_USERNAME
              valueFrom:
               secretKeyRef:
                name: db-user
                key: username
            - name: DB_PASSWORD
              valueFrom:
               secretKeyRef:
                name: db-user
                key: password

我试图在配置文件中找到错误或拼写错误，但仍然找不到。 producer-deployment.yml 文件有什么问题

Answer 1

多个问题:

1. 在 Service

   中应该是 apiVersion: v1 而不是 apiVerion: v1

2. Service 的 Spec.ports 形成错误。 nodePort、port、targetPort和protocol作为列表在ports下但是你的队形错了。

您的服务 yaml 应如下所示:

apiVersion: v1
kind: Service
metadata:
  name: producer-app
  labels:
    name: producer-app
spec:
  ports:
    - nodePort: 30163
      port: 9090
      targetPort: 9090
      protocol: TCP
  selector:
    app: producer-app
  type: NodePort

所以你的整体 yaml 应该是:

apiVersion: v1
kind: Service
metadata:
  name: producer-app
  labels:
    name: producer-app
spec:
  ports:
    - nodePort: 30163
      port: 9090
      targetPort: 9090
      protocol: TCP
  selector:
    app: producer-app
  type: NodePort
