08/08/2022, 4:55 AMistio doesn't use ingress, nginx ingress controller is the thing you are looking for, and you are in luck if you installed rke using rancher it's already installed.
All you need to do is create an ingress file, you can find instructions on how to format an ingress file on kubernetes docs

08/08/2022, 12:43 PMIs not this an ingress?
a

08/08/2022, 12:55 PMOK, some basic definitions,
ingress is a general name for inbound rule communication
egress is a general name for outbound rule communication.
Now with regard to istio, the thing that enforce ingress is a virtualservice + gateway.
Now when someone talks about ingress with regard to kubernetes that usually means that he is talking about ingress controller.
there are few notable ingress controllers the most common one is nginx ingress controller, you can also find an ingress controller on every popular cloud provider.

08/08/2022, 1:02 PMWith that said, you can also get the same goal using istio (i even prefer istio over ingress controller on some situations), but you need to really understand the difference between the two, and the effort that is needed to "make" each work, if all you need is some routes with some TLS, then using istio would be a overkill, but if you need to enforce a complex network policy with somewhat complex network scheme then you should use istio, i really don't see the point of using istio just for ingress routes

08/08/2022, 1:06 PMIs just my company used to use istio. But this is a Stagging environment so they don’t really care if I use Istio or nginx. I just wanted to follow the common practices but if I will get the same result with an easiest way with nginx, maybe on this environment I could consider it.
Is just i’m pretty new and I don’t really know how to configure it.

08/08/2022, 1:09 PMI can help you configure both, but i see very little reason to use istio for this scenario

08/08/2022, 1:10 PMFirst let's see if there is an ingress controller installed.
kubectl get svc -A | grep ingressambitious-motherboard-40337
08/08/2022, 1:24 PMthen there is no nginx-ingress controller installed

08/08/2022, 1:26 PMIs not that rke2-ingress-nginx-controller-admission?
a
ambitious-motherboard-40337
08/08/2022, 1:27 PMmissed it yes
ambitious-motherboard-40337
08/08/2022, 1:27 PMthis cluster is on the cloud?

08/08/2022, 1:31 PMthen why the services has no external ip 🤔
ambitious-motherboard-40337
08/08/2022, 1:33 PMthere is a chance someone played with this setup, the services are suppose to be of type LB but for some reason they are not
b
brainy-tomato-18651
08/08/2022, 1:34 PMEvery service I installed, was ClusterIP type. Maybe there is any that is installed like LB by default but I can change the type of the service make it LB type
a
ambitious-motherboard-40337
08/08/2022, 7:56 PMNo it should have been LB out of the bix
