Installing docker-ce in CentOS 8

Introduction

In CentOS 8, tools such as buildah and podman

At the same time there was a problem with Docker

RHEL 8 firewalld and docker-ce are not compatible with each other out of the box

docker-ce stands for Docker Community Edition install packages that depend on docker-ce in CentOS 8 it is more difficult than in CentOS 7

Here you can explore both a radical solution to the problem in the form of removing podman and ways to mess with the docker-ce version

Remove podman and buildah

If you don't use podman and buildah, you can completely remove them from CentOS

Briefly

sudo yum erase -and substitution builds
sudo yum install docker-ce docker-ce-ci containerd.io

In detail

For the sake of interest, mono check the version, but if you saw a message about conflict then we saw the podman version

podman --version

podman version 3.2.3

Delete podman and buldah together or separately

sudo yum erase -y podman buildah

yum remove -y podman

After docker-ce is installed, dependency problems should disappear

Without removing podman and buildah

If you don't want to delete podman and/or buildah, there are a number of tips about bypassing the conflict.

The result may depend on your system and is not guaranteed
