仅使用一个端口时需要多个端口名称

Question

我有一个端口指定如下。

我的应用-service.yaml

apiVersion: v1
kind: Service
metadata:
  labels:
    app: my-app
  name: my-app-service
  namespace: default
spec:
  externalTrafficPolicy: Cluster
  ports:
    - port: 80
      name: my-port
      protocol: TCP
      targetPort: 8000
  selector:
    app: my-app
  sessionAffinity: None
  type: NodePort

cloudbuild.yaml 总结：

steps:
  - name: gcr.io/cloud-builders/gcloud
  - name: gcr.io/cloud-builders/docker
  - name: gcr.io/cloud-builders/gke-deploy

出于某种原因，当 port1 甚至不存在时，我在请求 port1 上的名称参数时遇到错误。见下文。

输出：

Step #3: Applying deployment.
Step #3: Getting access to cluster "my-cluster" in "my-zone".
Step #3: Configuration files to be used: [{kind: Deployment, name: my-app} {kind: HorizontalPodAutoscaler, name: my-app-hpa} {kind: Service, name: my-app-service}]
Step #3: Applying configuration files to cluster.
Step #3: Warning: kubectl apply should be used on resource created by either kubectl create --save-config or kubectl apply
Step #3: The Service "my-app-service" is invalid: 
Step #3: * spec.ports[1].name: Required value

Kubernetes 版本：1.15.9-gke.24

有人知道我错过了什么吗？

Answer 1

似乎是 yaml 对齐问题。确保端口数组在 "ports"

下缩进

尝试：

apiVersion: v1
kind: Service
metadata:
  labels:
    app: my-app
  name: my-app-service
  namespace: default
spec:
  externalTrafficPolicy: Cluster
  ports:
    - name: http
      port: 80
      protocol: TCP
      targetPort: 8000
  selector:
    app: my-app
  sessionAffinity: None
  type: NodePort

重新创建 yaml 成功了：

kubectl delete -f service.yaml
kubectl apply -f service.yaml

仅使用一个端口时需要多个端口名称

Multiple port names required when only using one port
