Alpine Linux Image for DigitalOcean

This project uses alpinelinux/alpine-make-vm-image to create an Alpine Linux image for use in DigitalOcean droplets. The image collects hostname and root public key information from the DigitalOcean Metadata Service when the droplet is booted. The image also provides some sane defaults for things like disabling root login via sshd and the creation of a non-root admin user that has sudo access.

This repository contains submodules (for the VM image builder) which must be initialized. You should clone the repository recursively:

git clone --recursive https://github.com/brettbuddin/alpine-virt-do

Building

From Linux

Ensure you have gzip, qemu-img, qemu-nbd, and e2fsprogs dependencies installed.

$ sudo ./build.sh

From macOS

You will need Vagrant to build the image from a Linux VM.

$ vagrant up
$ vagrant ssh -c "cd /vagrant && sudo ./build.sh"

The build will pause towards the end to ask for a password. This is for the new administrative user the script is creating. It's safest to do this interactively.

Uploading to DigitalOcean

Upload the image at build/*.qcow2.gz at Images > Custom Images.
