Release v2021.10.01-0

Released on October 01, 2021

New Features

  • Containerd is now the default container runtime, replacing the previous default container runtime, Docker.
  • Log rotation will now be configured by default for the Docker add-on, where the max-size parameter for the log file is set to 10m.
  • Added the ability to configure log rotation through kubelet, which helps when using containerd instead of docker.
  • Re-enabled the ability to declare custom host preflight checks in the kURL installer spec.


  • When Longhorn is specified in an installer spec but an object store (e.g., MinIO) is not, the Registry add-on will be deployed with two replicas and a ReadWriteMany (RWX) volume for greater availability.

Bug Fixes

  • Fixed a bug that didn't allow User and Service Account tokens to authenticate to the kURL API.
