What is Rancher?
An open-source platform from SUSE for creating, importing and managing Kubernetes clusters from one dashboard, with central authentication, role-based access, monitoring and an app catalog.
Is Rancher free to self-host?
Yes. Rancher is Apache 2.0 licensed. You pay for the server and any Meetrix software fee shown on the AWS or Google Cloud listing. SUSE sells Rancher Prime separately, with 24x7 support.
Which clusters can Rancher manage?
RKE2 and K3s clusters it provisions, hosted Kubernetes services such as Amazon EKS, Azure AKS and Google GKE, and existing clusters you import.
How do I sign in the first time?
Open your Rancher domain and enter the admin password you set at launch, the AdminPassword stack parameter on AWS or the Admin password field in the Google Cloud deployment form, then confirm the server URL.
Does it set up SSL?
Yes. The image requests a Let's Encrypt certificate for your domain, on AWS automatically when the domain is hosted on Route 53. If that fails, a script on the server generates the certificate manually.
Which instance size should I choose?
t3a.large on AWS or e2-standard-2 on Google Cloud is the recommended starting point. Size up if Rancher will manage many clusters or nodes.
How do I upgrade?
Back up your server data, remove the old deployment and launch the new version from AWS Marketplace or Google Cloud Marketplace.
How does Rancher compare with Red Hat OpenShift?
Rancher is open source and manages many Kubernetes distributions, including EKS, AKS and GKE. OpenShift is a subscription platform with its own clusters, and its multi-cluster management is an add-on.
