Cloud-Managed Clusters

Hosted clusters (or managed clusters) refer to Kubernetes clusters managed by cloud providers such as Amazon (EKS), Google (GKE), Alibaba (ACK); Microsoft (AKS), IBM (IKS), DigitalOcean (DOKS), and others. Rancher allows you to manage these clusters by importing them into its interface or by creating them directly from the Rancher UI. These clusters integrate well with Rancher and can use many of the same features as Rancher-launched clusters, but there are some limitations, especially for non-EKS, GKE, AKS clusters.

• Certificate Rotation: Rancher supports certificate rotation only for hosted clusters managed by AWS EKS, Azure AKS, and Google GKE. For hosted clusters from other cloud providers, certificate rotation is not supported. This could change in future releases.

• Pod Security Policies: Configuring Pod Security Policies is not supported for hosted clusters, except for AWS EKS, Azure AKS, and Google GKE. However, users can implement Pod Security Admission (PSA), which is supported by Rancher for all hosted clusters.
