kubernetes - kubernetes上的 key 斗篷:入口HTTPS必需错误

Question

我有一个Kubernetes集群，在其中部署了以下部署和服务:

apiVersion: v1
kind: Service
metadata:
  name: keycloak
  labels:
    app: keycloak
    name: keycloak
spec:
  type: NodePort
  ports:
    - name: http
      protocol: TCP
      port: 8080
  selector:
    app: keycloak
    name: keycloak
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: keycloak
  labels:
    name: keycloak
    app: keycloak
spec:
  replicas: 1
  selector:
    matchLabels:
      app: keycloak
  template:
    metadata:
      name: keycloak
      labels:
        app: keycloak
        name: keycloak
    spec:
      restartPolicy: Always
      containers:
      - name: keycloak
        image: jboss/keycloak
        ports:
          - containerPort: 8080
            protocol: TCP
        resources:
          requests:
            cpu: 200m
            memory: 256Mi
          limits:
            cpu: 400m
            memory: 512Mi
        env:
          - name: KEYCLOAK_LOGLEVEL
            value: "DEBUG"
          - name: PROXY_ADDRESS_FORWARDING
            value: "true"
          - name: KEYCLOAK_USER
            value: "admin"
          - name: KEYCLOAK_PASSWORD
            value: "password"
          - name: DB_USER
            valueFrom:
              secretKeyRef:
                name: postgres-secret
                key: username
          - name: DB_PASSWORD
            valueFrom:
              secretKeyRef:
                name: postgres-secret
                key: password
          - name: DB_ADDR
            valueFrom:
              configMapKeyRef:
                name: postgres-configmap
                key: HOST
          - name: DB_PORT
            valueFrom:
              configMapKeyRef:
                name: postgres-configmap
                key: PORT
          - name: DB_DATABASE
            valueFrom:
              configMapKeyRef:
                name: postgres-configmap
                key: DATABASE
          - name: DB_VENDOR
            value: "postgres"

我运行keycloak的pod中的日志正在确认我的keycloak正在运行，并且正在使用提供的Postgres数据库。我尝试添加以下入口规则:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: keycloak
  annotations:
    kubernetes.io/tls-acme: "true"
    kubernetes.io/ingress.class: "nginx"
    ingress.kubernetes.io/force-ssl-redirect: "true"
spec:
  rules:
  - host: auth.mydomain.com
    http:
      paths:
      - path: /
        backend:
          serviceName: keycloak
          servicePort: 8080
      - path: /auth
        backend:
          serviceName: keycloak
          servicePort: 8080

我可以进入Keycloak主页，但是一旦单击管理控制台，我总是收到错误消息: We're sorry .... HTTPS required。将PROXY_ADDRESS_FORWARDING变量设置为“true”，无助于正确设置。我不只是想在端口8443上运行keycloak，所以我真的在寻找其他解决方案。

您需要在入口中设置TLS termination

spec:
  tls:
    - hosts:
      - auth.mydomain.com
      secretName: tls-secret

使用创建的 secret ，其中包含 auth.mydomain.com的证书:

apiVersion: v1
kind: Secret
metadata:
  name: tls-secret
  namespace: default
type: kubernetes.io/tls
data:
  tls.crt:LS0S[...]0tLhsrQo=
  tls.key:LS0t[...]LS1CRUdJ=

这将使您的入口 Controller 可以使用提供的TLS证书终止流量，并将未加密的HTTP流量转发到 keycloak服务。
