Release v1.4.0

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 are both simplified and easily automated, and they are entirely independent of the operating system and platform you’re running.

Enhancements

  • Introduced v1.24.6-rancher1-1 and v1.23.12-rancher1-1.

Known Major Issues

  • Ephemeral /var/lib/dockershim and /var/lib/cri-dockerd directories for kubelet container could cause kubelet/dockershim to send empty portMappings after upgrade. The workaround is to bind mount these directories by specifying extra_binds for kubelet service. See #2993.
  • In clusters where cloud_provider is configured and either address or internal_address does not contain a valid IP address (e.g., hostname or FQDN), kube-proxy will fail to start. See #1725.

Kubernetes Versions

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.
