如何创建HTTPS路由到正在使用Traefik和库伯内特斯监听Https的服务

Question

我是kubernetes和Traefik的新手。

我跟进教程：https://docs.traefik.io/user-guides/crd-acme/

我将其更改为在Scala中使用我的服务，即使用https和9463端口。我正在尝试使用kubernetes和traefik部署Scala服务。

当我直接转发到服务时：

kubectl port-forward service/core-service 8001:9463

我执行一个curl-k'https://localhost:8001/health'：

我得到了“{消息：Ok}”

但当我向traefik执行端口转发时

kubectl port-forward service/traefik 9463:9463 -n default

并执行卷曲-khttps://ejemplo.com:9463/tls/health'我收到一个“内部服务器错误”

我想问题是我的“核心服务”正在通过HTTPS协议监听，这就是我添加的方案：https。我试图通过留档找到解决方案，但令人困惑。

这些是我的yml文件：

从文档中

默认情况下，TLS路由器将终止TLS连接。但是，可以指定直通选项来设置请求是否应“按原样”转发，同时保持所有数据加密。

在您的情况下，需要启用SSL直通，因为pod需要HTTPS流量。

apiVersion: traefik.containo.us/v1alpha1  
kind: IngressRoute  
metadata:  
  name: ingressroutetls
  namespace: default
spec:  
  entryPoints:
    - websecure
  routes:
  - match: Host(`ejemplo.com`) && PathPrefix(`/tls`)
    kind: Rule
    services:
    - name: core-service
      port: 9463
      scheme: https
  tls:
    certResolver: default
    passthrough: true
