K3s, the lightweight- certified Kubernetes distribution created by Rancher Labs, has become a popular choise for IoT and edge computing. But Rancher users have been asking for tighter integration between Rancher Server and K3s.

With Rancher 2.4, new Rancher HA installations can be installed on K3s clusters with external SQL databases. This setup simplifies cluster administration with no need to operate etcd. Management of the database can be offloaded to hosted solutions like RDS running MySQL.

In this Kubernetes Master Class, Rancher Software Engineers will discuss and demo the new K3s support in Rancher, review use cases and best practices.
