Why build your own Nginx service, as opposed to writing an Ingress and deploying an Ingress controller?
I honestly think that the Ingress is way more complicated for beginners to understand then a service type LoadBalancer routing to a reverse proxy.
At least I had a hard time in the beginning understanding the Ingress really works.
From what I understand, Ingresses are just a way of saying "Here's a path, it corresponds to this service." However, setting up an Ingress controller is, in some cases, needlessly complicated imo. I like that minikube and GKE ship with one by default, but that didn't prepare me for having to set one up on my own, especially given if I want it to use HTTPS.
Like Michael already answered, the Service with an externalIP was a very simple solution, while an Ingress is much more complex. Actually, I wouldn't even know how to use an Ingress e.g. on a minikube or a local cluster that does not have a dedicated load balancer. It might be worth a look, but currently my priority is: 1) finish CI for multiarch images, so that you can deploy kube-alive on ARM and amd64 without changing anything in the manifests (almost done) 2) fix the security problems I mentioned in the article and 3) add more experiments, like observing live how a rolling update happens. Then, at prio 4) I might add support for GKE, AKS and EKS.
