如何使用 nginx-ingress 将我的外部域“uat.test.com”添加到我的 kubernetes 集群？

Question

我是 kubernetes 的新手，并且对于来自 godaddy 的外部域的入口 nginx 有问题。它被称为“https://uat.test.com”。我为 nginx-ingress 创建了一些 yaml，但我做不到。如何使用 nginx-ingress 将“uat.test.com”添加到我的 kubernetes 集群？

下面;它们是我有趣和有压力的冒险的步骤。

1. 创建组和命名空间：

az group create --name aks-group --location eastus2

az aks create --resource-group aks-group --name aks-cluster --node-count 3 --generate-ssh-keys -s Standard_B2ms --disable-rbac

kubectl create namespace ingress-basic

1. 凭据：

az aks get-credentials -g aks-group -n aks-cluster

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v0.43.0/deploy/static/provider/cloud/deploy.yaml
 
az aks get-credentials -g aks-group -n aks-cluster

kubectl --namespace ingress-basic get services -o wide -w nginx-ingress-ingress-nginx-controller

1. 安装 ingress-nginx：

helm install ingress-nginx ingress-nginx/ingress-nginx
   
helm repo update
    
helm install nginx-ingress ingress-nginx/ingress-nginx --namespace ingress-basic --set controller.replicaCount=2
     
kubectl --namespace ingress-basic get services -o wide -w nginx-ingress-ingress-nginx-control

aks-helloworld-one.yaml ：

kubectl apply -f aks-helloworld-one.yaml --namespace ingress-basic

kubectl apply -f hello-world-ingress.yaml

当我写地址“https://uat.test.com”时

// 在 cmets 中讨论过

您需要将集群入口控制器的公共 IP 地址绑定到您的 DNS 名称。这不会发生在 AKS（或您的 k8s 配置中的任何地方）中。您需要通过您的 DNS 提供商来执行此操作。
