Fedora Update Notification
FEDORA-2026-49fd0d9636

--------------------------------------------------------------------------------

Name        : moby-engine
Product     : Fedora 42
Version     : 29.4.0
Release     : 1.fc42
URL         : https://github.com/moby/moby
Summary     : The open-source application container engine
Description :
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 do not 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.
