How to install docker engine in CentOS 8

In this short blog post, Let’s see how to install Docker engine in CentOS. I thought it would be pretty straight forward process of issuing a command or two and be done with it, but I ran into a small hurdle that I would like to share.

So, I was following official documentation(https://docs.docker.com/engine/install/centos/) from Docker for installing on my CentOS(8) machine. As you can see below, I had my repo all setup and ready to go.

When I tried to install as per documentation, I ran into dependency issues for containerd.io package (CentOS 8 as of the day of this writing doesn’t support few specific versions of containerd.io package).

Error:
Problem: package docker-ce-3:19.03.9-3.el7.x86_64 requires containerd.io >= 1.2.2-3, but none of the providers can be installed.

We have couple of work arounds here…
Install CentOS 7 containerd.io package manually and then install docker-ce engine/upgrade and voila. ( This is what I am going to show you guys below)
or
use –nobest option as suggested by yum in order to install appropriate version of containerd.io package.

Alright, now it’s time to manually download and install containerd.io package. Get the latest stable package details for CentOS 7 from here:

sudo yum install -y https://download.docker.com/linux/centos/7/x86_64/stable/Packages/containerd.io-1.2.13-3.2.el7.x86_64.rpm
