Kublr Quick Start

The Kublr Demo/Installer is a simple and convenient demo version of Kublr running in Docker that allows you deploy Kubernetes clusters. You can also install a non-production licensed version of the full Kublr Platform from the Kublr Demo/Installer.

By downloading and using the Kublr Demo/Installer and Kublr, you agree to the Terms of Use and Privacy Policy.

Running Kublr

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

Kublr Installation Guide

What you should know about the Kublr Demo/Installer

The Kublr Demo/Installer is a lightweight platform that allows you to run a demo or limited functionality, dockerized Kublr version. You can use it to:

  • Manage a standalone Kubernetes cluster;
  • Manage the full feature Kublr Platform;

The Kublr Demo/Installer stores all data about the clusters inside the Docker container. Therefore, if you delete the Docker container, you will lose all cluster and Kublr platform related data — though you won’t lose the cluster and platform itself. The Kublr team recommends using the Kublr Demo/Installer to verify that a Kubernetes cluster can be created in your environment. So, test it before deploying a full and more permanent Kublr Platform in the cloud or on-premise.

Kublr Demo/Installer Installation Prerequisites

  1. Download and install Docker
  2. 64-bit operating system to run the Kublr Demo/Installer
  3. To deploy a Kubernetes cluster or the full Kublr Platform, you’ll need an AWS, Azure, GCP account or an on-premise environment.

Running Kublr

Open a terminal and launch following command:

sudo docker run --name kublr -d --restart=unless-stopped -p HOST_PORT:9080 -e KUBLR_HOST=HOST_IP:HOST_PORT kublr/kublr:1.13.0
  • KublrVersion (1.13.0) is provided in an email, or check the latest version Releases;
  • HOST_PORT is a port available both on you workstation for the browser and available outside, from the network;

Here’s a Kublr Demo/Installer launch command example:

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

The Kublr UI will be available on http://localhost:9080 (admin/kublrbox)

If you are going to set up a bare metal cluster on the Kublr platform, please add this additional parameter KUBLR_HOST, where the HOST_IP is external and available from the network IP address workstation which is being used to run the Kublr Demo/Installer:

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

If you have already started the Kublr Demo/Installer without the option KUBLR_HOST or your IP address has been changed (for example to switch networks), please use this command to correct the KUBLR_HOST:

docker exec -i kublr /bin/bash -c 'echo "KUBLR_HOST=HOST_IP:HOST_PORT" > /ip.external'; docker restart kublr

Running Kublr in an air-gapped environment

In order to run the Kublr Demo/Installer in an air-gapped environment (without connectivity), please request the launch command via email or use this contact us form.

The Kublr UI

By default, the Kublr UI, Keycloak UI, and API will be available on the exposed port 9080. After downloading the Docker image, it will take less than a minute for Kublr to start and be viewable.

If you use KUBLR_HOST to define the public IP address and public port number of the host running Kublr (e.g. 192.168.99.234:9981), run this command:

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