Today, Rancher Labs released version 2.4 of their eponymous software, Rancher. Rancher is a Kubernetes Cluster management platform. Darren Shepherd, Shannon Williams, Sheng Liang, and Will Chan founded Rancher Labs in 2014. The company provides software to assist with Kubernetes and Docker workflows.
Rancher Labs focused on scalability for their latest release. Rancher 2.4 increases the number of supported clusters up to 2,000, along with 100,000 nodes. There’s also a “preview” version that supports 1,000,000 clusters. I wouldn’t be surprised if they’re seeing some stability issues at that scale since they limited the number of clusters to less than 1% of their preview maximum.
Aiming to make managing their steadily increasing number of clusters easier, Rancher also included improvements for maintenance workflows. When Rancher 2.4 kicks off an upgrade remotely, the process is managed on local K3s clusters. This allows upgrades and patches to use local resources to update without needing a stable connection to the management server. Once the changes are complete, the cluster syncs back up with the management server. Rancher 2.4 also allows customers to upgrade Kubernetes clusters and nodes without application interruption. Customers can also select and configure their upgrade strategy for add-ons so that DNS and Ingress do not experience service disruption.
Recognizing that many customers may not want to deal with setting up as many on-premise clusters as they now support, Rancher Labs offers Hosted Rancher deployments. Each customer gets a dedicated AWS instance of a Rancher Server with a 99.9 percent SLA.
