Install a Docker Engine on Linux
Docker Engine is an open source containerization technology for building and containerizing your applications.Docker Engine is available on a variety of Linux platforms, macOS and Windows 10 through Docker Desktop, and as a static binary installation.
Refer : https://docs.docker.com/engine/install/ for version where you are trying to install.
I am installing on Linux Mint. Will use Ubuntu method
Uninstall old versions
sudo apt-get remove docker docker-engine docker.io containerd runc
As it is not installed in my system it will not uninstall
himanshu@himanshu-server:~/Desktop$ sudo apt-get remove docker docker-engine docker.io containerd runc

There are multiple methods to install. I will use script to install
Install using the convenience script
Docker provides a convenience script at get.docker.com to install Docker into development environments quickly and non-interactively. The convenience script is not recommended for production environments, but can be used as an example to create a provisioning script that is tailored to your needs.
1) Download the script
curl -fsSL https://get.docker.com -o get-docker.sh
2) Install now
sudo sh get-docker.sh
Took 5 mins to complete.
himanshu@himanshu-server:~/Desktop$ sudo sh get-docker.sh

================================================================================
To run Docker as a non-privileged user, consider setting up the
Docker daemon in rootless mode for your user:
dockerd-rootless-setuptool.sh install
Visit https://docs.docker.com/go/rootless/ to learn about rootless mode.
To run the Docker daemon as a fully privileged service, but granting non-root
users access, refer to https://docs.docker.com/go/daemon-access/
WARNING: Access to the remote API on a privileged Docker daemon is equivalent
to root access on the host. Refer to the 'Docker daemon attack surface'
documentation for details: https://docs.docker.com/go/attack-surface/
================================================================================
3) Check Docker Version
himanshu@himanshu-server:~/Desktop$ docker --version
Docker version 20.10.17, build 100c701
4) Check Docker is community or enterprise edition
himanshu@himanshu-server:~/Desktop$ docker version
Client: Docker Engine - Community
Version: 20.10.17
API version: 1.41
Go version: go1.17.11

5) Run a Simple Container to test
himanshu@himanshu-server:~/Desktop$ sudo docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world

Status: Downloaded newer image for hello-world:latest
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
