Kublr Demo/Installer Release 1.8.0 (2018-02-09)

This release has a known critical issue, use Kublr 1.21.2 or later instead

Due to docker image gcr.io/kubernetes-helm/tiller:v2.14.3 discontinued in the Google Image repository in August 2021, ( related issue: “Make Tiller Image Available on Docker Hub” ), Kublr may fail to complete cluster create and update.

The cluster hangs in “Creating” or “Updating” state indefinitely or for a very long time, or goes to “Error” state, in all cases with Tiller pod unhealthy due to Tiller image not available.

All versions of Kublr before 1.21.2 (including this one), and Kublr Agent versions earlier than the ones included in Kublr 1.21.2 are affected.

The issue and available solutions are described in the troubleshooting guide on Kublr support portal.

Migration to the latest Kublr Agents and Kublr Control Plane versions or at least Kublr 1.21.2 is recommended.
