Install Docker and Docker Compose on Linux Fedora

Docker is an open platform for developing, shipping, and running applications. Docker enables you to separate your applications from your infrastructure so you can deliver software quickly. With Docker, you can manage your infrastructure in the same ways you manage your applications. By taking advantage of Docker’s methodologies for shipping, testing, and deploying code quickly, you can significantly reduce the delay between writing code and running it in production.

Docker Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a YAML file to configure your application’s services. Then, with a single command, you create and start all the services from your configuration.

Fedora Linux is a Linux distribution developed by the Fedora Project which is sponsored primarily by Red Hat (an IBM subsidiary) with additional support and sponsors from other companies and organizations. Fedora contains software distributed under various free and open-source licenses and aims to be on the leading edge of open-source technologies. Fedora is the upstream source for Red Hat Enterprise Linux.

Docker buildx with multi-CPU architecture support

Docker images can support multiple architectures, which means that a single image may contain variants for different architectures, and sometimes for different operating systems, such as Windows.

When running an image with multi-architecture support, docker automatically selects the image variant that matches your OS and architecture.

Most of the Docker Official Images on Docker Hub provide a variety of architectures. For example, the busybox image supports amd64, arm32v5, arm32v6, arm32v7, arm64v8, i386, ppc64le, and s390x. When running this image on an x86_64 / amd64 machine, the amd64 variant is pulled and run.
