Kublr Demo/Installer Release 1.13.0 (2019-08-06)

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.

Kublr Quick Start

sudo docker run --name kublr -d --restart=unless-stopped -p 9080:9080 kublr/kublr:1.13.0

The Kublr Demo/Installer is a lightweight, dockerized limited-functionality Kublr Platform which can be used to:

• Test setup and management of a standalone Kubernetes cluster
• Setup a full-featured Kublr Platform

The Kublr Demo/Installer stores all the data about the created clusters inside the Docker container. If you delete the Docker container you will lose all data about the created clusters and the Kublr platforms. However, you will not lose the cluster and platform itself. We recommend using the Kublr Demo/Installer to verify if a Kubernetes cluster can be created in your environment and to experiment with it. To manage your clusters and benefit from all features, create a full-featured permanent Kublr Platform in any cloud or on-premise.
