At the time of this writing, Docker has two major versions-Docker CE (Community Edition) and Docker EE (Enterprise Edition). This article will focus on the installation of Docker CE on various Linux operating system distributions.

Docker is a container runtime engine that allows you to package applications with all dependencies into standardized units for software development.

Roustabout Container Package the complete software File system Contains everything it needs to run: code, run, System Tools, System library -Everything you can install on the server. This ensures that no matter what environment it is running in, it will always run the same content.

Here, we will introduce the installation of Docker CE on Ubuntu, Debian, Fedora, CentOS and Arch Linux distributions.
