无法在 WSL 2 上访问应用程序运行 skaffold 和 docker 桌面

Question

无法访问节点 js 应用程序我运行在具有 docker 桌面的 K8s 集群中。下面是对象 Skaffold 配置：

apiVersion: skaffold/v2beta26
kind: Config
deploy:
  kubectl:
    manifests:
      - ./objects/*
build:
  local:
    push: false
  artifacts:
    - image: sq/accounts-backend
      context: ../accounts-backend
      docker:
        dockerfile: Dockerfile.dev
      sync:
        manual:
          - src: "**/*.js"
            dest: .
          - src: "public/**/*.css"
            dest: .

部署：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: accounts-backend-deployment
spec:
  replicas: 2
  selector:
    matchLabels:
      component: accounts-backend
  template:
    metadata:
      labels:
        component: accounts-backend
    spec:
      containers:
        - name: accounts-backend
          image: sq/accounts-backend
          ports:
            - containerPort: 5000
          env:

集群IP：

apiVersion: v1
kind: Service
metadata:
  name: accounts-backend-cluster-ip-service
spec:
  type: ClusterIP
  selector:
    component: accounts-backend
  ports:
    - port: 5000
      targetPort: 5000

入口：

apiVersion: networking.k8s.io/v1
# UPDATE API
kind: Ingress
metadata:
  name: ingress-service
  annotations:
    kubernetes.io/ingress.class: "nginx"
    nginx.ingress.kubernetes.io/use-regex: "true"
    # ADD ANNOTATION
    nginx.ingress.kubernetes.io/rewrite-target: /
    # UPDATE ANNOTATION
spec:
  rules:
    - http:
        paths:
          - path: /api/?(.*)
            # UPDATE PATH
            pathType: Prefix
            # ADD PATHTYPE
            backend:
              service:
                # UPDATE SERVICE FIELDS
                name: accounts-backend-cluster-ip-service
                port:
                  number: 5000

我能够通过执行 skaffold dev 验证 Deployment 已启动并且应用程序运行。我尝试访问本地主机、127.0.0.1 和 docker 的内部 IP，但无法访问该应用程序。我在浏览器中尝试时连接时间太长，连接被拒绝。

入口的输出描述：

Name:             ingress-service
Namespace:        default
Address:
Default backend:  default-http-backend:80 (<error: endpoints "default-http-backend" not found>)
Rules:
  Host        Path  Backends
  ----        ----  --------
  *
              /api/?(.*)   accounts-backend-cluster-ip-service:5000 (10.1.0.50:5000,10.1.0.51:5000)
Annotations:  kubernetes.io/ingress.class: nginx
              nginx.ingress.kubernetes.io/rewrite-target: /
              nginx.ingress.kubernetes.io/use-regex: true
Events:       <none>

默认情况下，skaffold dev只有port-forwardsuser-definedport-forwards，即explicitly defined in the skaffold.yaml。例如：

portForward:
- resourceType: deployment
  resourceName: accounts-backend-deployment
  port: 5000
  localPort: 8080

您还可以使用 skaffold dev --port-forward=user,services port-forward 服务以及任何 user-defined port-forwards.

Skaffold port-forwarding 不包括入口：目前是 cluster-specific。例如，对于 minikube，您需要单独运行 minikube tunnel，或者如果使用 nginx-ingress.

或者 minikube service -n ingress-nginx --url ingress-nginx-controller
