if you mean v2.7.0, that's been EOL since Nov 2024. if you really did mean v2.0.7, that's been EOL for... a bit longer. Best to start with the latest rancher, which is currently v2.12.0.

Caveat: there are issues awaiting resolution if you want to install the monitoring tools with 2.12.0, a resurrection of an old bug.

thanks! I will upgrade to v2.12.0 is certmanager optional for rancher ?

We've installed certmanager manually, I don't think there's an integrated app for it.

cert-manager is needed or not for rancher depends on your SSL configuration https://ranchermanager.docs.rancher.com/getting-started/installation-and-upgrade/install-upgrade-on-a-kubernetes-cluster#3-choose-you[…]onfiguration

the doc says: when

ingress.tls.source=secret

cert manager is not required, so it's confusing for me what will happen when I disable ingress completely
