CentOS 8에서 최신 버전의 Docker를 설치하는 방법

CentOS 8에서 최신 버전의 Docker CE(Community Edition)를 설치하는 방법

CentOS 8은 기본적으로 Podman을 지원하지만 Docker를 설치하려면 공식 Docker 저장소를 사용해야 합니다.

테스트 환경

$ cat /etc/redhat-release 
CentOS Linux release 8.4.2105

기존 Docker 제거

sudo dnf remove -y docker-* containerd runc

Docker 공식 저장소 추가

sudo dnf -y install dnf-plugins-core
sudo dnf config-manager \
  --add-repo https://download.docker.com/linux/centos/docker-ce.repo

저장소 메타데이터 업데이트

sudo dnf clean all
sudo dnf makecache

사용 가능한 Docker 버전 확인

sudo dnf list docker-ce --showduplicates | sort -r
sudo dnf list docker-ce-cli --showduplicates | sort -r
