Hi All, any idea about how many Kubernetes clusters can Rancher handle for cluster management?

From https://rancher.com/products/rancher "Rancher supports from 1 to 1,000,000 clusters from a single console with built-in security capabilities, running any CNCF-certified Kubernetes distribution."

have you looked at this document: https://rancher.com/docs/rancher/v2.6/en/installation/requirements/#rke-and-hosted-kubernetes

@hundreds-evening-84071 Yes Is it saying we need an XX-Large machine do deploy Rancher for managing 2000 clusters?

I believe it would also depend on number of nodes, but that is my guess. If you are managing 2000 clusters, best to contact Rancher for further clarification. I've only 4 clusters so I'm no where near where you are
