Unable to install docker on RHEL 8

I am tying to installing docker on rhel 8.

I am getting the below error not sure why please help.

[root@mano mano]# yum install docker-ce-18.09.9
Cannot find a valid baseurl for repo: InstallMedia, ignoring this repo.
Last metadata expiration check: 0:11:14 ago on Fri 20 Sep 2019 02:42:53 PM IST.
Error: 
 Problem: package docker-ce-3:18.09.9-3.el7.x86_64 requires containerd.io >= 1.2.2-3, but none of the providers can be installed
  - cannot install the best candidate for the job
  - package containerd.io-1.2.2-3.3.el7.x86_64 is excluded
  - package containerd.io-1.2.2-3.el7.x86_64 is excluded
  - package containerd.io-1.2.4-3.1.el7.x86_64 is excluded
  - package containerd.io-1.2.5-3.1.el7.x86_64 is excluded
  - package containerd.io-1.2.6-3.2.el7.x86_64 is excluded
  - package containerd.io-1.2.6-3.3.el7.x86_64 is excluded
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

I have installed containered.io

RHEL have blocked Containerd for some reason.

You have to manually install it by running the command line below;

yum -y install https://download.docker.com/linux/centos/7/x86_64/stable/Packages/containerd.io-1.2.6-3.3.el7.x86_64.rpm

After that, yum install docker-ce should works fine.

Note that you must also disable firewalld, otherwise DNS is broken.

For that, you can run:

systemctl disable firewalld

For Rhel 8 try the following steps:

First, install DNF:

yum install DNF

dnf install -y dnf-utils \
  device-mapper-persistent-data \
  lvm2
dnf config-manager \ 
  --add-repo \
  https://download.docker.com/linux/centos/docker-ce.repo
dnf install docker-ce
systemctl start docker
systemctl enable docker

While installing, if you are prompted to accept the GPG key, accept the same by entering y
