nginx - Kubernetes nginx ingress redirect domains to cluster

Question

I want to redirect two namecheap domains testA.com and testB.com to two different services (websites) on my raspberry pi cluster.

I set everything up using an updated form from this guide. This means that k3s, metalb, nginx ingress and cert-manager are fully deployed and working.

% kubectl get pods --all-namespaces

The guide describes it for dynDNS. How should I do this if I had two domains and two different websites. Is this done with a containerised certbot? Or do I need CNAME?

您可以运行该命令并检查外部或暴露给 Internet IP的LoadBalancer IP。

你可以将此IP作为A记录或CNAME记录到DNS端，你就完成了。您的两个域都将流量指向 Kubernetes 集群，并且在 Kubernetes 内部，您可以创建入口路由或记录以将流量转移到特定服务。
