Failing to install Docker on RHEL7.9

  docker, installation, redhat, yum

I am a BEGINNER following the video tutorial of my class, everyone made the same system. AWS EC2 RHEL7.9.

I spent the last 7 hrs trying to follow solutions on stack exchange but I can’t make any of them work for my problem. Your help is much appreciated.

Info and steps taken:

Becoming root

$ sudo su -

All necessary files seem to be here

[[email protected] ~]# ll

-rw-------. 1 root root  7407 Jan 28  2019 anaconda-ks.cfg
-rw-r--r--. 1 root root 40212 Sep 16  2019 container-selinux-2.107-3.el7.noarch.rpm

Checking again which rhel release:

[[email protected] ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.9 (Maipo)

Epel was previously installed – Nothing to do

[[email protected] ~]# yum localinstall epel-release-latest-7.noarch.rpm
Loaded plugins: amazon-id, search-disabled-repos
Examining epel-release-latest-7.noarch.rpm: epel-release-7-13.noarch
epel-release-latest-7.noarch.rpm: does not update installed package.
Nothing to do

Docker ce is here

Install fails, packages not found

Why are none of the docker packages available?

[[email protected] ~]#yum install docker-ce docker-ce-cli
Loaded plugins: amazon-id, search-disabled-repos
No package docker-ce available.
No package docker-ce-cli available.
No package available.
Error: Nothing to do

Any ideas? Keep in mind I am a beginner, thanks for your constructive comments.
