尝试运行traefik-deeployment.yml时，服务“traefik-ingress Service”无效

Question

我正在尝试将traefik部署为microk8s中的入口控制器。当我通过以下命令创建文件时: microk8s.kubectl -f traefik-deployment.yml

我得到的错误是:服务"traefik-ingress- Service“无效：

我试着在网上搜索，但找不到任何相关的帮助。

这是我的traefik-deployment文件：

apiVersion: v1
kind: ServiceAccount
metadata:
  name: traefik-ingress-controller
  namespace: kube-system
---
kind: Deployment
apiVersion: apps/v1 
metadata:
  name: traefik-ingress-controller
  namespace: kube-system
  labels:
    k8s-app: traefik-ingress-controller
spec:

  selector:

      k8s-app: traefik-ingress-controller
  template:

      labels:
        k8s-app: traefik-ingress-controller
        name: traefik-ingress-controller

      containers:

        ports:
        - name: http
          containerPort: 80
        - name: https
          containerPort: 443
        - name: webui
          containerPort: 8080
        args:
        - --api
        - --kubernetes
        - --logLevel=INFO
---
kind: Service
apiVersion: v1
metadata:
  name: traefik-ingress-service
  namespace: kube-system
spec:
  selector:
    k8s-app: traefik-ingress-controller
  ports:
    - name: http
      port: 80
      protocol: tcp
    - name: https
      port: 443
      protocol: tcp
    - name: webui
      port: 8080
      protocol: tcp

  type: NodePort

我得到的输出是：

serviceaccount/traefik-ingress-controller created
deployment.apps/traefik-ingress-controller created
The Service "traefik-ingress-service" is invalid: 
* spec.ports[0].protocol: Unsupported value: "tcp": supported values: "SCTP", "TCP", "UDP"
* spec.ports[1].protocol: Unsupported value: "tcp": supported values: "SCTP", "TCP", "UDP"
* spec.ports[2].protocol: Unsupported value: "tcp": supported values: "SCTP", "TCP", "UDP"

它似乎已经创建了服务，但当我从以下位置看到它时：

sudo microk8s.kubectl get all --all-namespaces

我看到容器处于错误状态。

Answer 1

它只是说用大写字母写"TCP“，而不是用小写字母。

但是容器的错误与此无关。这只是一个公开部署的服务。
