Smaller and faster, for automated cloud operations
Minimal Ubuntu is the smallest Ubuntu base image for your cloud operations. These images are less than 50% the size of the standard Ubuntu server image, and boot up to 40% faster. Images of Minimal Ubuntu 16.04 LTS and 18.04 LTS are available for use now in Amazon EC2, Google Compute Engine (GCE), LXD and KVM/OpenStack.
Tiny container base image
The 29MB Docker image for Minimal Ubuntu 18.04 LTS serves as a highly efficient container starting point, and allows developers to deploy multicloud containerized applications faster. For modern Docker workflows with Kubernetes, the minimal Ubuntu image provides a balance of compatibility, familiarity, performance and size. This is the standard Ubuntu 18.04 LTS image on the Docker Hub.
Cloud images also contain the optimised kernel for each cloud and supporting boot utilities.
Fully compatible with all Ubuntu packages
While the footprint of Minimal Ubuntu is greatly reduced, it preserves full compatibility with standard Ubuntu operations. Any Ubuntu package can be installed on Minimal Ubuntu. Get exactly the image you need by simply adding your required packages, with dependencies, to a Minimal Ubuntu base image.
Minimal Ubuntu is designed for completely automated operations, with none of the usual human-friendly utilities for comfortable interactive usage. Editors, documentation, locales and other user-oriented features of Ubuntu Server have been removed. What remains are only the vital components of the boot sequence. Images still contain ssh, apt and snapd so you can connect and install any package you’re missing. The unminimize tool lets you ‘rehydrate’ your image into a familiar Ubuntu server package set, suitable for command line interaction.
Optimized for cloud hypervisors
Minimal Ubuntu uses the optimized kernels on Amazon Web Services and Google Cloud. The downloadable Minimal Ubuntu image ships with a KVM-optimised kernel and tuned for boot speed and size.
Minimized security cross-section
With fewer installed packages, Minimal Ubuntu images will avoid some security vulnerabilities and require fewer updates over time. Use of Minimal Ubuntu will reduce overall bandwidth consumption for an institution and require less storage.
