需要帮助为hcloud-cloud- controller -manager配置Nginx入口控制器

Question

我正在尝试跟随this suggestion使用Hetzner load balancer作为Nginx的入口控制器。

具有以下配置的helm install ingress-nginx：

controller:
  config:
    use-proxy-protocol: "true"
  replicaCount: 3
  service:
    type: LoadBalancer
    annotations:
      load-balancer.hetzner.cloud/name: nginx-controller-new
      load-balancer.hetzner.cloud/location: hel1
      load-balancer.hetzner.cloud/use-private-ip: true
      load-balancer.hetzner.cloud/algorithm-type: least_connections
      load-balancer.hetzner.cloud/uses-proxyprotocol: true
      load-balancer.hetzner.cloud/hostname: somehost.com

部署：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: echo1
spec:
  selector:
    matchLabels:
      app: echo1
  replicas: 3
  template:
    metadata:
      labels:
        app: echo1
    spec:
      containers:
        - name: echo1
          image: hashicorp/http-echo
          args:
            - "-text=echo1"
          ports:
            - containerPort: 5678
---
apiVersion: v1
kind: Service
metadata:
  name: echo-service
spec:
  selector:
    app: echo1
  ports:
    - name: http
      protocol: TCP
      port: 80
      targetPort: 5678
  ipFamilyPolicy: PreferDualStack

---
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: nginx
spec:
  ingressClassName: nginx
  rules:
    - http:
        paths:
          - pathType: Prefix
            path: "/"
            backend:
              service:
                name: echo-service
                port:
                  number: 80
      host: somehost.com

安装后，Hetzner负载均衡器配置成功，但无法检测到服务：

我现在有点不知所措。如何将echo1应用连接到入口-nginx-控制器服务？我查看了Echo1，但我找不到像service.selector这样的东西来针对Echo1的服务并使其公开可用。有人能帮我吗？还有别的选择吗？

我不是Kubernetes大师(更像是菜鸟)，但我是用L4负载均衡器工作的。

必须将注释设置到您的Ingress：

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  annotations:
    kubernetes.io/ingress.class: nginx

在不使用nginx-ingress的情况下使用它，这对我很有效(没有使用您的标签进行测试)

apiVersion: "apps/v1"
kind: "Deployment"
metadata:
  name: "nginx-hello-world"
  labels:
    app: "hello-world"
spec:
  selector:
    matchLabels:
      app: "hello-world"
  strategy:
    type: "Recreate"
  template:
    metadata:
      labels:
        app: "hello-world"
    spec:
      containers:
        - image: "rancher/hello-world"
          name: "nginx-hello-world"
          imagePullPolicy: "Always"
          ports:
            - containerPort: 80
              name: "http"

用于HTTP的服务(用于测试您的部署)

---
apiVersion: "v1"
kind: Service
metadata:
  name: "nginx-hello-world"
  labels:
    app: "hello-world"
  annotations:
    load-balancer.hetzner.cloud/name: lb-development
    load-balancer.hetzner.cloud/hostname: somehost.com
    load-balancer.hetzner.cloud/protocol:   http
    load-balancer.hetzner.cloud/health-check-port: 10254
spec:
  type: LoadBalancer
  selector:
    app: "hello-world"
  ports:
    - name: "http"
      port: 80
      targetPort: 80

对于SSL

apiVersion: v1
kind: Service
metadata:
  name: nginx-hello-world
  labels:
    app: hello-world
  annotations:
    load-balancer.hetzner.cloud/hostname: somehost.com
    load-balancer.hetzner.cloud/http-certificates: managed-certificate-1-wildcard-somehost.com
    load-balancer.hetzner.cloud/name: lb-development
    load-balancer.hetzner.cloud/protocol: https
spec: 
  ports:
  - name: https
    nodePort: 32725
    port: 443
    protocol: TCP
    targetPort: 80
  selector:
    app: hello-world
  type: LoadBalancer
