Hello together,
I am currently trying to setup a fresh rancher server installation into a single node RKE cluster. I therefore followed the descriptions in the documentation and the rancher academy. I am unfortunately stuck after installation of letsencrypt. When trying to install rancher via helm3 I get the following error:
helm3 install rancher rancher-stable/rancher --version v2.5.3 --namespace cattle-system --set hostname=rancher.example.org --set ingress.tls.source=letsEncrypt --set letsEncrypt.email=name@example.org
Error: unable to build kubernetes objects from release manifest: unable to recognize “”: no matches for kind “Issuer” in version “cert-manager.io/v1”
I have tried now with cert-manger 1.1.0 and 1.0.4. Can someone give me a hint how I can resolve the issue. I have found this topic as a bug on rancher github. Unfortunately, no description of a solution.
Hope that helps!
