Oracle Cloud: Create Partitioned Disk with Cloud-Init

Creating a Partitioned Disk Using Cloud-Init on Oracle Cloud

Abstract: Learn how to create a partitioned disk and format it with ext4 for mounting using Cloud-Init on an Oracle Cloud instance.

Created: 2024-12-26 by

Introduction

In this article, we will walk you through the process of creating a partitioned disk using Cloud-Init on Oracle Cloud. Cloud-Init is a powerful utility for automating the setup and configuration of cloud instances. It supports various cloud providers, including Oracle Cloud. In this tutorial, we will use a YAML configuration file to create a new partition on a secondary disk and format it for use as an ext4 file system.

Prerequisites

Before we begin, make sure you have the following:

  • An Oracle Cloud account and a new instance running.
  • SSH access to the instance.
  • Basic knowledge of Linux command line.

Setting Up the Environment

First, let's connect to the instance using SSH:

$ ssh @

Replace with your Oracle Cloud username and with your instance's public IP address.

Creating the Disk

To create a new disk, you can use the Oracle Cloud Console or the Oracle Cloud CLI. In this tutorial, we will use the CLI:

$ oracle iam api-token create --scope admin --pwd  --file token.pem
$ oracle iam avatar create --file avatar.pem --display-name "My Avatar" --is-public false --token 
$ oracle vm create --compartment-id  --subnet-id  --ssh-key-file  --shape OC51 --operating-system  --image-version  --instance-shape  --instance-name  --availability-domain  --ssh-private-key-file  --admin-password  --assigned-ip-address  --vnic-id  --boot-volume-size  --add-bootstrap-volume-size  --add-data-volume-size  --add-data-volume-size  --add-data-volume-size  --add-data-volume-size
