microk8s中的Traefik allways 404 Traefik

Question

我在一个简单的小型虚拟服务器上部署了一个microk8s单节点集群。目前，我没有使用证书SSL (默认情况下是Traefik证书)。80版本的入口工作正常，我可以从HTTP浏览正确入口的网页，但当我尝试在https中运行时，Traefik显示404。

如果有人能帮我，我将不胜感激。

非常感谢

这是我的Traefik配置&我的入口配置。

Answer 1

看起来您缺少入口点websecure annotation，因此Traefik也可以在端口443上工作

    traefik.ingress.kubernetes.io/router.entrypoints: web, websecure

请注意，如果您希望将所有流量重定向到HTTPS，则必须在您的DaemonSet配置中包含以下内容：

...
        - --entrypoints.web.http.redirections.entryPoint.to=websecure
        - --entrypoints.websecure.http.tls.certResolver=default
....

这可能会对a write up on how to use a K8s ingress with Traefik v2有所帮助。
