06/29/2022, 4:04 PMHello! I have installed rke2 with 3 nodes, everything works fine, but adding additional ingress-es with different ingressClassName still just shows the nginx 404 error page, am I understanding correctly when I add other ingress controllers it should use them?
@fierce-summer-6167 this one

06/30/2022, 7:34 PMDo you know why you're seeing a 404 and not 503?
a
ambitious-plastic-3551
06/30/2022, 7:35 PMyes, because rke2 is "default" one directly listening on the 80,443 ports

06/30/2022, 7:35 PMWhat is the ingress type?
a
ambitious-plastic-3551
06/30/2022, 7:36 PMI installed two more controllers, traefik and apisix, but if I set Ingress with that class to some resource it's still nginx 404
so basically Ingress in this fashion has no effect
f
fierce-summer-6167
06/30/2022, 7:39 PMAh. I meant the ingress service type.
a
ambitious-plastic-3551
06/30/2022, 7:40 PMI have NodePort mostly
f
fierce-summer-6167
06/30/2022, 7:40 PMIf it's a NodePort, are you checking the NodePort? If it's a LoadBalancer, are you checking the load balancer endpoint?
a
ambitious-plastic-3551
06/30/2022, 7:40 PMeven though I would prefer ClusterIP
f
fierce-summer-6167
06/30/2022, 7:40 PMClusterIP is local to the cluster.
a
ambitious-plastic-3551
06/30/2022, 7:41 PMBut currently I don't get it what I need to achieve this, or how this class is working
For me ingress is something like you have a reverse proxy and then it checks a class, and find the suitable service
f
fierce-summer-6167
06/30/2022, 7:44 PMIt sounds like in your case that if you're trying to determine if the ingress is working correctly, you'll have to query the nodeport of the service.
Are you doing that, or ports 80/443? Are they the service ports for one of your ingresses?
a
ambitious-plastic-3551
06/30/2022, 7:45 PMI think rke2-ingress-nginx is doing the hostPort
## Use host ports 80 and 443
## Disabled by default
hostPort:
# -- Enable 'hostPort' or not
enabled: true
ports:
# -- 'hostPort' http port
http: 80
# -- 'hostPort' https port
https: 443

06/30/2022, 7:48 PMYou're looking for something like:
kubectl get services --namespace <ingress namespace>
a
ambitious-plastic-3551
06/30/2022, 7:48 PMSo my question is... can I even achieve this ingress thing to be more configurable just within Kubernetes, and what steps/measures...
nginx isn't even in let's say exception admission clusterip
f
fierce-summer-6167
06/30/2022, 7:51 PMYes, but I've never done it. We've deployed NGINX Ingress controller and Istio (for example, but Istio is not an ingress controller) on the same cluster, but not multiple ingresses. The Kubernetes project has some documentation here:
https://kubernetes.github.io/ingress-nginx/user-guide/multiple-ingress/
Sounds like you were on the right track with ingress classes.
a
ambitious-plastic-3551
06/30/2022, 7:56 PMas a workaround I can use existing Ingress to forward traffic, but is manual job
Thank you for the input
