How to Install Docker on Ubuntu 22.04: A Step-by-Step Guide
Docker has become a cornerstone of modern software development and system administration. Whether you're running containers for local development, hosting web apps, or experimenting with microservices, Ubuntu 22.04 (Jammy Jellyfish) is one of the most reliable platforms to do it on. Here's exactly how to get Docker up and running — and what to understand before you start.
What Docker Actually Does

On Ubuntu 22.04, Docker runs natively via the Linux kernel's built-in container features — cgroups and namespaces — which means you get solid performance without hypervisor overhead.
There are two main Docker products to know:

|---|---|
| Docker Engine | The core daemon and CLI — what most developers install on Linux |
| Docker Desktop for Linux | A GUI-based app with additional tooling, suited for desktop workflows |
