Running Confluence on Azure VM – Preparing Ubuntu image in Hyper-V [1/4]

This is a multi-post guide on how to prepare and run Confluence in an Azure VM. While there are prebuilt images for Ubuntu available in Azure this guide will show how to deploy your own image.

Preparations

Requirements:

Enable Hyper-V from powershell:

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V -All
Code language: PowerShell (powershell)

Open Hyper-V and create a new virtual machine:

  • The disk must be VDH (fixed sized) and have a minimum size of 8GB
  • Assign an external (Internet) network card
  • Mount ISO for Ubuntu Server

Installing and configure Ubuntu

Start the VM and console into it to complete the Ubuntu installer steps:

  • For archive setup change the mirror address to azure.archive.ubuntu.com
  • In storage configuration you can uncheck LVM group setup if not required
  • Install OpenSSH server

When install has finished SSH into the server to begin customizations.

Our customization of Ubuntu Server is now complete.

Proceed by copying the VM disk to a temporary folder.

In case of errors please refer to the official documentation at Prepare an Ubuntu virtual machine for Azure.

In next step we will prepare and configure a new VM in Azure using the locally created Ubuntu Server image:
