Hi together, I went go big or go home and had some issue understanding how to work with ingress. I deploy a few things with ansible, so I thought deploying via k3s-ansible is a good starting point for me. Everthings worked fine, so I fast forwarded to longhorn. Worked like a charm. Got into the documentation of longhorn and stranded at the exposing of the LonghornUI. And thats the point where I struggled: Do I have traefik running? It seemed so. Did I understand it until now? fo shizzle nope. I started reading here and there and got a grasp that I probably need an ingress controller, so I deployed it via

kubectl apply -f <https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.12.1/deploy/static/provider/baremetal/deploy.yaml>

which seems to be the latest release for me. That provided me the address of one of my control nodes via

kubectl -n longhorn-system get ingress

. But the curl results in an 404 page not found. which he also did before. So my issue I don't really know where to read next neither do I understand until now, what I am making wrong. My cluster looks like this: NAME STATUS ROLES AGE VERSION k3s-cn-01 Ready control-plane,etcd,master 92m v1.30.2+k3s1 k3s-cn-02 Ready control-plane,etcd,master 91m v1.30.2+k3s1 k3s-cn-03 Ready control-plane,etcd,master 91m v1.30.2+k3s1 k3s-wn-001 Ready <none> 90m v1.30.2+k3s1 k3s-wn-002 Ready <none> 90m v1.30.2+k3s1

traefik is an ingress controller. If you deployed ingress-nginx you now have two ingress controllers. Which is probably not what you want, and it is not going to work well for you.

So what had I missing instead: • Deployed via official k3s-ansible • Deployed longhorn via chart described in the docs • Tried to expose the longhorn UI described in the docs via basic auth ( I think here it went south) • Deployed nginx ingress (that was also faulty)

yes

Sometimes it is easy and just in front. Was also a bit misleaded by following statement: "This project is intended to provide a "vanilla" K3s install."

where did you find that statement?

Here: https://github.com/k3s-io/k3s-ansible at the bottom of the readme.

huh. well, a vanilla install of K3s comes with traefik, which you have… so that is accurate.

Yes was my own confusion creating the trouble. I look forward to see the result tomorrow, after configuring the dashboard correctly.
