Hi all, is it possible to have Rancher (deployed on a 3 node k3s via Helm) behind two hostnames? Currently using any other hostname (or IP) than the "hostname" specified via helm values gets a 404

As there is a global "server url" setting, i highly doubt using two of them is supported.

But then the host header in the clients request doesn’t match and I get a 404

The host header in the client should be the cname

Yes. My issue at hand is that our LB in front of Rancher is sometimes a bit unstable. I want to test a second one but that’s just not possible without a second entry point. The only thing is to have some dns split brain where I let a few clients resolve the same Hostname to a different IP.

monkey around with /etc/hosts (in contradiction with rule 30 but oh well)

the ingress that sits in front of rancher is configured to match requests on the rancher hostname. You could probably update the ingress configuration to match multiple hostnames, but rancher itself will still use only the configured address when generating links and internal redirects.

Yes. I’ll try with the etc/hosts tinkering.
