Release v0.2.3

Important

  • RKE v0.2.x releases enable certificate rotation support. This feature addresses a 1 year expiration on certificates generated by RKE v0.1.x for secure Kubernetes cluster components communication [#450]. To renew the cluster certificates, run the following command:

    ./rke cert rotate --config cluster.yml

Major Bug Fixes since v0.2.2

  • When control plane and etcd are deployed on the same node, put local etcd node ip first in etcd-servers kube-api argument [1368]
  • Fixed an issue when RKE provisioned clusters having k8s version 1.13.x could get broken when one of the etcd nodes goes down. The situation is caused by [Kubernetes upstream issue) , and RKE fix prevents it from happening [20311]
  • Fixed an issue when RKE provisioned clusters could get broken by adding a new control plane node to it due to the certificates not being re-generated properly on the node addition [16151]

Known Major Issues

  • RKE will not finish deployment if certain network mounts exist on the target node [#964]

Kubernetes Versions

Each version of RKE has a specific list of supported Kubernetes versions. If a version is defined in kubernetes_version in the cluster.yml and is not found in this list, then RKE will error out. 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.
