Release v1.2.18-rc1

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

• Updated NGINX Ingress Controller image to v1.1.0 to address critical CVEs. See #36136.

Major Bug Fixes

• Fixed a regression in nginx ingress template where tcp-services-configmap and udp-services-configmap weren't applied on upgrade from nginx-ingress-v0.30.0 to >=controller-v0.31.0. See #35943.

Known Major Issues

• 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.
