Note that cloud-init may already be installed on your system (some Linux distributions install cloud-init by default). In this guide, we’ll use an Ubuntu 18.04 server and so will use apt to download and install the cloud-init package. In general, the cloud-init package should be available in your OS’s package manager, so if you’re not using a Debian-based distribution, you should substitute apt in the following steps with your distribution-specific package manager command. Steps for installing cloud-init will vary depending on the operating system you have installed. Cloud-init is a set of scripts that runs at boot to configure certain cloud instance properties like default locale, hostname, SSH keys and network devices.

To begin, we will install the cloud-Init initialization package. Step 1 - Installing Cloud-Init and Enabling SSH To learn how set up s3cmd for use with your Space, consult the s3cmd 2.x Setup Guide.

To learn how to create a Space, consult the Spaces Quickstart. This can be an attached block storage volume, an external USB drive, an additional physical disk, etc.Ī DigitalOcean Space and the s3cmd file transfer utility configured for use with your Space. To learn how to do this on Debian 9, consult Initial Server Setup with Debian 9.Īn additional storage device used to store the disk image created in this guide, preferably as large as the disk being copied. To create a new user and grant it administrative privileges on Ubuntu 18.04, follow our Initial Server Setup with Ubuntu 18.04.

Note that these instructions have only been tested with an Ubuntu 18.04 system, and steps may vary depending on your server’s OS and configuration.īefore you begin with this tutorial, you should have the following available to you:Ī Linux or Unix-like system that meets all of the requirements listed in the Custom Images product documentation. In the cases where you need to manually create a disk image of your system, you can follow the instructions in this guide. Many cloud providers and virtualization environments also provide tools to export virtual disks to one of the compatible formats listed above, so, if possible, you should use these to simplify the import process.

You can then install software and applications on top of this base image to bake a new image, using tools like Packer and VirtualBox. If possible, you should use one of the DigitalOcean-provided images as a base, or an official distribution-provided cloud image like Ubuntu Cloud. Finally, we’ll boot up a Droplet using the uploaded image. Following that, we’ll upload this compressed image file to DigitalOcean Spaces, from which we can import it as a Custom Image. Then, we’ll create the image using the dd command-line utility and compress it using gzip. To do this, we’ll configure the system and install some software prerequisites. We’ll begin by ensuring that our image meets the Custom Images requirements.

If you don’t already have a compatible image to upload to DigitalOcean, you can create and compress a disk image of your Unix-like or Linux system, provided it has the prerequisite software and drivers installed.

If you want to change the encryption, click the Encryption pop-up menu, then choose an encryption type.Įnter a new name for the image in the Save As field, click Save, then click Done.DigitalOcean’s Custom Images feature allows you to bring your custom Linux and Unix-like virtual disk images from an on-premises environment or another cloud platform to DigitalOcean and use them to start DigitalOcean Droplets.Īs described in the Custom Images documentation, the following image types are supported natively by the Custom Images upload tool:Īlthough ISO format images aren’t officially supported, you can learn how to create and upload a compatible image using VirtualBox by following How to Create a DigitalOcean Droplet from an Ubuntu ISO Format Image. Hybrid image (HFS+/ISO/UDF): This disk image is a combination of disk image formats and can be used with different file system standards, such as HFS, ISO, and UDF. When you use a master disk image to create other DVDs or CDs, all data is copied exactly. It includes a copy of all sectors of the disk image, whether they’re used or not. Read/write: Allows you to add files to the disk image after it’s created.ĭVD/CD master: Can be used with third-party apps. Read-only: The disk image can’t be written to, and is quicker to create and open.Ĭompressed: Compresses data, so the disk image is smaller than the original data. In the Disk Utility app on your Mac, choose Images > Convert, select the disk image file you want to convert, then click Open.Ĭlick the Image Format pop-up menu, then choose a new image format.
