Create an Ubuntu Worker Cluster on CentOS

This page explains how to create an Ubuntu worker cluster on an existing CentOS.

Note

This page is specifically for the offline mode, using the DCE 5.0 platform to create a worker cluster, where both the CentOS platform and the worker cluster to be created are based on AMD architecture. Heterogeneous (mixed AMD and ARM) deployments are not supported during cluster creation; however, after the cluster is created, you can manage a mixed deployment by adding heterogeneous nodes.

Prerequisite

Download and Import Ubuntu Offline Packages

Please ensure you are logged into the bootstrap node! Also, make sure that the clusterConfig.yaml file used during the DCE 5.0 deployment is still available.

Download Ubuntu Offline Packages

Download the required Ubuntu OS packages and ISO offline packages:

os-pkgs-ubuntu2204-v0.18.2.tar.gz Ubuntu 20.04 OS package https://github.com/kubean-io/kubean/releases/download/v0.18.2/os-pkgs-ubuntu2204-v0.18.2.tar.gz
ISO Offline Package ISO Package http://mirrors.melbourne.co.uk/ubuntu-releases/

Import OS and ISO Packages into MinIO on the Bootstrap Node
