Fedora 35: FEDORA-2021-B5A9A481A2 Critical Moby-Engine Update

Docker is an open source project to build, ship and run any application as a

lightweight container.

Docker containers are both hardware-agnostic and platform-agnostic. This means

they can run anywhere, from your laptop to the largest EC2 compute instance and

everything in between - and they don't require you to use a particular

language, framework or packaging system. That makes them great building blocks

for deploying and scaling web apps, databases, and backend services without

depending on a particular stack or provider.
