This article is for those looking for a detailed and clear guide on how to install Docker Engine and Docker Compose on Ubuntu Server.

Docker is a container management system that allows you to “package” an application or website with all its environment and dependencies into a container that you can easily manage. For example, transfer to another server, scale, or update.

In this guide, we will consider the case when you already have a server with the Ubuntu Server 20.04 LTS operating system installed on it.

You can read more about how to install Ubuntu Server 20.04 LTS in my guide “Install Ubuntu Server 20.04 LTS”.

In addition, OpenSSH must be installed on the server, and port 22 must be open in order to be able to connect to the server using the SSH protocol.

To install OpenSSH on a server, you can use the command:

sudo apt install openssh-server

If you plan to connect to the server using the Windows operating system, you can use PuTTY or MobaXterm.

This guide describes how to connect to a server using the iTerm2 terminal emulator installed on the macOS operating system.

We connect to the server on which you plan to install the Docker Engine.

Download the Docker Engine and Docker Compose installation script using the command:

curl -fsSL https://get.docker.com -o get-docker.sh
