This article uses Amazon Linux 2 on AWS to do the following:
First, update yum as follows.
[ec2-user@ip-xxx-xxx-xxx-xxx ~]$ sudo yum update -y
Then install docker.
[ec2-user@ip-xxx-xxx-xxx-xxx ~]$ sudo amazon-linux-extras install docker -y
After the installation is complete, start the docker daemon.
[ec2-user@ip-xxx-xxx-xxx-xxx ~]$ sudo service docker start
Add ec2-user to the docker group.
This is not required, but you can now use the `docker``` command without `sudo```.
[ec2-user@ip-xxx-xxx-xxx-xxx ~]$ sudo usermod -a -G docker ec2-user
After executing the above command, close the terminal once. Then reconnect.
First, start the container with the `run``` command. If the image has not been pulled, you can pull it before launching. The option `-it``` allows you to enter inside the launched container.

[ec2-user@ip-xxx-xxx-xxx-xxx ~]$ docker run -it centos

[root@xxx /]#
[ec2-user@ip-xxx-xxx-xxx-xxx ~]$ yum install python3 -y
By entering the python3 command as shown below, you can enter interactive mode and know that it has been installed.
[root@xxx /]# python3
