OS 요구 사항

• To install Docker CE, you need a maintained version of CentOS 7. Archived versions aren’t supported or tested.

  The centos-extras repository must be enabled. This repository is enabled by default, but if you have disabled it, you need to re-enable it.

  The overlay2 storage driver is recommended.

In general, the following configurations work on recent versions of the Linux distribution: Linux distribution Recommended storage drivers Alternative drivers Docker Engine - Community on Ubuntu overlay2 or aufs (for Ubuntu 14.04 running on kernel 3.13) overlay¹, devicemapper², zfs, vfs Docker Engine - Community on Debian overlay2 (Debian Stretch), aufs or devicemapper(older versions) overlay¹, vfs Docker Engine - Community on CentOS overlay2 overlay¹, devicemapper², zfs, vfs Docker Engine - Community on Fedora overlay2 overlay¹, devicemapper², zfs, vfs Supported backing filesystems With regard to Docker, the backing filesystem is the filesystem where /var/lib/docker/ is located. Some storage drivers only work with specific backing filesystems.

Docker CE 설치

1. 저장소를 설정하고 설치하는 방법 : 가장 일반적인 방법으로 설치 및 업그레이드 작업을 쉽게하기 위해
2. 수동으로 설치 : PM 패키지를 다운로드하여 수동으로 설치 하고 업그레이드를 완전히 수동으로 관리 (for not Internet)
3. 자동화된 스크립트로 설치 : 테스트 및 개발 환경에서 사용하여 Docker를 설치

저장소를 설정하고 설치하는 방법

• 필수 패키지 설치

  • 
    

    $ sudo yum install -y yum-utils \ device-mapper-persistent-data \ lvm2

    
    

• Stable repository 설정

  $ sudo yum-config-manager \ --add-repo \ https://download.docker.com/linux/centos/docker-ce.repo
