WHAT’S RANCHER V2.1.0

What’s Rancher v2.1.0 ? Rancher v2.1.0 introduces new improvements to Kubernetes cluster operations and app management, as well as a migration path for users moving from Rancher’s Cattle orchestrator introduced in 1.x to Rancher Kubernetes. Summary • Latest - v2.1.0 - rancher/rancher:latest • Stable - v2.0.8 - rancher/rancher:stable Version

What’s Rancher v2.1.0 ? Webinar October Online Meetup: Migrating from Rancher 1.6 to 2.1 In our October Rancher Meetup, we’ll discuss how to transition various aspects of Rancher 1.6 applications to Rancher 2.0. We’ll look at key terminology differences and parallels, how to implement important elements, and transition from Cattle Compose to YAML specs. Date: Tuesday, October 23rd, 2018 Time: 1:00 PM (US Eastern Time) https://info.rancher.com/2018-10-23-how-to-migrate-from-rancher1- to-rancher2

Details

What’s Rancher v2.1.0 ? • EXPERIMENTAL support for Windows Kubernetes clusters - Administrators can now create EXPERIMENTAL Windows Kubernetes clusters. • EXPERIMENTAL support for Kubernetes 1.12 [#15872] - Users can now create EXPERIMENTAL Kubernetes 1.12 clusters. Details
