Установка docker-ce в CentOS 8

Введение

В CentOS 8 появились такие инструменты как buildah и podman

Одновременно с этим возникла проблема c Docker

RHEL8 firewalld и docker-ce не совместимы друг с другом из коробки

docker-ce означает Docker Community Edition установить пакеты, зависящие от docker-ce в CentOS 8 сложнее чем в CentOS 7

Здесь вы можете изучить как радикальное решение проблемы в виде удаления podman так и способы подшаманить с версией docker-ce

Удалить podman и buildah

Если вы не пользуетесь podman и buildah можно их полностью удалить из CentOS

Коротко

sudo yum erase -y podman buildah
sudo yum install docker-ce docker-ce-cli containerd.io

Подробно

Ради интереса моно проверить версию, но если вы видели сообщение о конфликте то видели и версию podman

podman --version

podman version 3.2.3

Удалите podman и buldah вместе либо раздельно

sudo yum erase -y podman buildah

yum remove -y podman
