Installing OpenNebula on Alpine Linux

OpenNebula is an open-source cloud computing platform that allows users to manage and deploy virtual machines and other cloud infrastructure resources. In this tutorial, we will guide you through the process of installing OpenNebula on Alpine Linux, the latest version.

Prerequisites

Before proceeding with the installation of OpenNebula on Alpine Linux, make sure that you have the following prerequisites:

• A running instance of Alpine Linux
• Root access to the system
• A stable internet connection

Step 1: Updating system packages

First, it's essential to update the system packages before starting with the installation process. You can use the following command to update the system packages on Alpine Linux:

# apk update && apk upgrade

Step 2: Installing required dependencies

OpenNebula has several dependencies that need to be installed before we can proceed with the installation. You can install the necessary dependencies by running the following command:

# apk add sudo gcc make g++ ruby ruby-dev openldap-dev libxml2-dev libxslt-dev zlib-dev libssl1.1 libcrypto1.1 openssl-dev sshpass

Step 3: Adding OpenNebula repository

Next, we will add the OpenNebula repository to the Alpine Linux system. You can use the following commands to add the repository:

# wget -q -O- http://downloads.opennebula.io/repo/Debian/repo.key | sudo apt-key add -
# echo "deb http://downloads.opennebula.io/repo/5.12/Alpine/3.12 stable opennebula" | sudo tee /etc/apk/repositories.d/opennebula.repo

Step 4: Installing OpenNebula

After adding the repository, we can install OpenNebula by running the following command:

# apk add opennebula-server opennebula-sunstone

This command will install the OpenNebula server and the Sunstone GUI.

Step 5: Configuring OpenNebula

After the installation, you can use the following command to generate the configuration file:

# /usr/share/one/install_gems --yes

Once the configuration file is generated, you can start the OpenNebula services by running the following command:

# systemctl start opennebula opennebula-sunstone

To configure OpenNebula from the Sunstone GUI, open your web browser and navigate to http://your-server-ip:9869.

Conclusion

In this tutorial, we have installed OpenNebula on Alpine Linux. You can now start using OpenNebula to manage and deploy virtual machines and other cloud infrastructure resources on your system.
