Ubuntu Core documentation

Welcome to the home of Ubuntu Core documentation.

Ubuntu Core is Ubuntu, engineered for IoT and embedded systems. It’s easy to deploy, tamper-resistant and hardened against corruption.

Ubuntu Core features:

  • snap-based, security first: snaps are secure, easy to build, and painless to distribute. Public/private key validation ensures what’s running is exactly what’s intended to run

  • simple, consistent installation and deployment: Ubuntu Core is installed via an immutable image, which can be either installed or built specifically for your platform and application

  • a read-only filesystem: apps run in isolation from each other and access to system resources is only granted with explicit permissions

  • transactional updates: signed, autonomous and atomic, updates can withstand unpredictable hardware and network conditions, even to the operating system

From a single Raspberry Pi, to a deployment of tens of thousands, it’s the ideal platform for anything that needs to run securely, be ever-ready, autonomously updated, and tamper-proof.
