In production install Rancher in a K8s cluster with Helm

10/13/2023, 5:48 PM@witty-jelly-95845 I am curious as to why you would recommend outside of the cluster for production.

10/20/2023, 5:40 PMFirstly the Rancher docs note that the "Docker installation is for development and testing environments only" - see https://ranchermanager.docs.rancher.com/pages-for-subheaders/other-installation-methods
So you install Rancher into a Kubernetes cluster but not any of the ones you want to manage - same applies to Harvester. If you install Rancher within Harvester (doesn't matter whether Docker on a VM or within Kubernetes in VMs) and Harvester breaks then chances are you've also broken Rancher.
Sure for dev/test it's okay but you do so knowing the risks - I currently have Rancher in Docker in a Harvester VM in my home lab but I'm looking to change that.
