从 Azure k8s 外部访问 Web 应用程序

Question

从群集外部使用已在 Azure DNS 区域中定义的名称访问 aks 容器中的 Web 应用程序运行的最佳方式是什么？外部 DNS 服务器对此有帮助吗？

Answer 1

我会设置一个 ingress 指向您公开网络应用程序的服务。

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: simple-fanout-example
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /
spec:
  rules:
  - host: your.web.app.address
    http:
      paths:
      - path: /
        backend:
          serviceName: service
          servicePort: 8080

Ingress exposes HTTP and HTTPS routes from outside the cluster to services within the cluster. Traffic routing is controlled by rules defined on the Ingress resource.

    internet
        |
   [ Ingress ]
   --|-----|--
   [ Services ]

An Ingress may be configured to give Services externally-reachable URLs, load balance traffic, terminate SSL / TLS, and offer name based virtual hosting. An Ingress controller is responsible for fulfilling the Ingress, usually with a load balancer, though it may also configure your edge router or additional frontends to help handle the traffic.

An Ingress does not expose arbitrary ports or protocols. Exposing services other than HTTP and HTTPS to the internet typically uses a service of type Service.Type=NodePort or Service.Type=LoadBalancer.

I would recommend reading Create an ingress controller in Azure Kubernetes Service (AKS), or use Azure Application Gateway as an ingress this is explained here and you can find tutorials on GitHub
