Docker Enterprise is a complex tool with many components available for use. Luckily, Mirantis Launchpad makes the installation process for Docker EE clusters easier. In this lab, you will have the opportunity to build your own multi-server Docker EE cluster using Launchpad.
Learning Objectives
Successfully complete this lab by achieving the following learning objectives:
- Install Mirantis Launchpad
Install Mirantis Launchpad on the UCP Manager server. You can use launchpad version 1.14.0.
- Generate Certificates for DTR
Generate a Certificate Authority (CA) and accompanying certificates for your Docker Trusted Registry instance. You will need these to set up your cluster configuration file.
- Create the Cluster
Create a cluster configuration file, then create the cluster itself using Launchpad.
A dedicated user called
launchpadhas already been created on each server for Launchpad’s use. This user already has all of the necessary permissions required by Launchpad on all three servers. On the UCP Manager server, you can find a public and private key file for the launchpad user in/home/cloud_user.
