Kublr Demo/Installer Release 1.12.0 (2019-05-16)

Quick Start

sudo docker run --name kublr -d --restart=unless-stopped -p 9080:9080 kublr/kublr:1.12.0

Kublr Demo/Installer is a lightweight tool for running a limited-functionality Kublr Platform inside a Docker container and installing a full Kublr Control Plane. It can be used to:

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

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 Kublr platforms. You will not lose the cluster and platform itself. The Kublr team recommends using Kublr Demo/Installer to check that a Kubernetes cluster can be created in your environment and to experiment. We also recommend creating a full-featured and durable Kublr Platform, in any cloud or on-premise, with the full power Kublr platform to manage your Kubernetes clusters.
