you don’t appear to have installed Rancher?

do you have link to "air gap installation" of rancher?

Follow this guide: https://docs.ranchermanager.rancher.io/v2.5/getting-started/quick-start-guides/deploy-rancher-manager/helm-cli To get the image on your system, pull it and save it as a tar, sheepdip it and then import: https://stackoverflow.com/questions/30225779/best-practices-for-using-docker-in-an-air-gapped-environment

do that but for 2.6, not 2.5

thanks
