Well, there is some question about the Ingress I'm pretty curious about, Does the Kubernetes Ingress support internal requests? For Example what if I want to proxy my requests through the Ingress Between my Microservices?

(The reason, why I'm asking about it, is actually because I want to enable SSL Communication between my Microservices, but don't really want to use Some Kind of. Istio to implement it, so I hope there is some more easier solutions for that :)

Thanks

In theory, yes. But realistically, no. Since to have a valid SSL cert that is accepted, you need to somehow verify you own the hostname.

You can't complete the DNS challenge since you don't own the "cluster.local" domain that is used for in-cluster DNS, and the certificate issuers such as Symantec and Entrust won't issue a certificate in that name because again you can't verify you own the domain.

And you can't complete HTTP challenge since "cluster.local" won't route to your specific cluster.

I've come up with Cert-Manager eventually, because it turned out to be most optimal way in compare with others, tutorial to set it up into your k8s cluster: https://www.youtube.com/watch?v=hoLUigg4V18&t=501s
