OpenNebula is an open-source cloud computing platform used to manage data center infrastructures. It is used to deploy and manage virtual machines, containers, and Kubernetes clusters. In this tutorial, you will learn how to install OpenNebula on Clear Linux Latest.
Before installing OpenNebula, we need to install its required dependencies:
sudo swupd bundle-add cluster-storage
sudo swupd bundle-add cloud-compute
sudo swupd bundle-add cloud-control
To install OpenNebula on Clear Linux Latest, you need to follow these steps:
Create a new file /etc/yum.repos.d/opennebula.repo with the following content:
