Alpine Linux Usage Statistics

Natanael Copa · October 2026

Summary

This report collects public and CDN data on Alpine Linux usage as of October 2026. The official alpine Docker image has 12.4 billion pulls, and 55 of the 141 Docker Official Images publish Alpine variants, more than for any other base OS. Of the Docker Hub downloads that ecosyste.ms can attribute to a base OS, 49% are of images built on Alpine and 40% of images built on Debian.

Requests to Alpine's package CDN, which reflect installed systems and CI builds rather than container pulls, grew from 1.2 billion a month in January 2021 to 13.2 billion in September 2026.

Create Alpine Linux unified kernel image with netboot

This explains how to create an Alpine Linux unified kernel image (UKI) with netboot.

For this we need:

• a kernel
• an initramfs image
• a modloop image (a squashfs image with the kernel modules for the kernel)
• the ukify tool from systemd
