kubernetes - 如果 https 流量，我如何将入口转发到 ssl 端口(443)

Question

入口如何将 https 流量转发到服务的端口 443(最终到我的容器上的 8443)？我是否必须对我的入口进行任何更改，还是自动完成。

在 GCP 上，我有一个第 4 层平衡器 -> nginx-ingress Controller -> 入口

我的入口是:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: ingress-keycloak
  annotations:
    kubernetes.io/ingress.class: "nginx"
    certmanager.k8s.io/issuer: "letsencrypt-prod"
    certmanager.k8s.io/acme-challenge-type: http01


spec:
  tls:
  - hosts:
    - mysite.com
    secretName: staging-iam-tls
  rules:
  - host: mysite.com
    http:
      paths:
      - path: /auth
        backend:
          serviceName: keycloak-http
          servicePort: 80

我在网上搜索，但我没有看到达到 443 的明确例子。它总是 80(或 8080)

我的服务 keycloak-http是(被省略，我的容器实际上在 8443 监听)

apiVersion: v1
kind: Service
metadata:
  creationTimestamp: 2019-05-15T12:45:58Z
  labels:
    app: keycloak
    chart: keycloak-4.12.0
    heritage: Tiller
    release: keycloak
  name: keycloak-http
  namespace: default
 ..
spec:
  clusterIP: ..
  externalTrafficPolicy: Cluster
  ports:
  - name: http
    port: 80
    protocol: TCP
    targetPort: http
  - name: https
    port: 443
    protocol: TCP
    targetPort: 8443
  selector:
    app: keycloak
    release: keycloak
  sessionAffinity: None
  type: NodePort
status:
  loadBalancer: {}

尝试这个:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: ingress-keycloak
  annotations:
    kubernetes.io/ingress.class: "nginx"
    nginx.ingress.kubernetes.io/backend-protocol: "HTTPS"
    certmanager.k8s.io/issuer: "letsencrypt-prod"
    certmanager.k8s.io/acme-challenge-type: http01
spec:
  tls:
  - hosts:
    - mysite.com
    secretName: staging-iam-tls
  rules:
  - host: mysite.com
    http:
      paths:
      - path: /auth
        backend:
          serviceName: keycloak-http
          servicePort: 443
