After I created a traefik daemonset, I created a service as loadbalancer on port 80, which is the Traefik proxy port and the node got automatically registered to it. If i hit the elb i get the proxy 404 which is OK because no service is registered yet
I then created a nodeport service for the web-ui. targeted port 8080 inside the pod and 80 on clusterip. I can curl the traefik ui from inside the cluster and it retruns traefik UI
I then created an ingress so that when i hit elb/ui it gets me to the backend web-ui service of traefik and it fails. I also have the right annotations in my ingress but the elb does not route the path to the traefik ui in the backend which is running properly
What am i doing wrong here? I can post all my yml files if required
UPD

How did it fail? Did you get error 404, error 500, or something else?
Also, for traefik-web-ui
service, you don't need to set type: NodePort
, it should be type: ClusterIP
.
When you configure backends for your Ingress, the only requirement is availability from inside a cluster, so ClusterIP
type will be more than enough for that.
Your service should be like that:
apiVersion: v1
kind: Service
metadata:
name: traefik-web-ui
spec:
selector:
app: traefik
ports:
- name: http
targetPort: 8080
port: 80
Option PathPrefixStrip
can be useful because without it request will be forwarded to UI with /ui
prefix, which you definitely don't want.
All other configs look good.
