Rancher Kubernetes Engine (RKE) is a CNCF-certified Kubernetes distribution that runs entirely within Docker containers. It works on bare-metal and virtualized servers. With RKE, the installation and operation of Kubernetes is both simplified and easily automated, and it’s entirely independent of the operating system and platform you’re running.
Enhancements
- Switched to using standard base64 encoding for Docker authentication, which fixes an issue where cluster provisioning fails when using a private registry with authentication [#28004]
Known Major Issues
- In clusters where
cloud_provider
is configured, and eitheraddress
orinternal_address
does not contain a valid IP address (e.g. hostname or FQDN), kube-proxy will fail to start. [#1725]

Each version of RKE has a specific list of supported Kubernetes versions. If you want to use a different version than listed below, you will need to update Kubernetes using the system images option in your cluster.yml
