Docker RPM 파일 준비
외부 인터넷을 활용할 수 없는 네트워크 환경에서, rpm 패키지 파일들을 이용하여 Docker를 설치하는 방법을 정리한 문서입니다.
운영환경 : CentOS 7.6 / DMZ와 유사하게 특정 대역 등에서만 접속이 가능한 네트워크 환경
외부 인터넷을 사용할 수 있는 동일한 CentOS 7.6 장비 또는 VM에서 아래와 같이 Docker 설치를 위하여 필요한 rpm 패키지 파일들을 다운로드 받은 후, 운영할 장비에 rpm 패키지 파일들을 업로드하여 수동으로 설치합니다.
Docker 레포지토리를 위한 yum-utils 및 기본 도구 설치
Docker 레포지토리를 위하여 필요한 패키지 파일 다운로드하고 설치합니다.
$ yum install -y yum-utils device-mapper-persistent-data lvm2 --downloadonly --downloaddir=/root/rpms/yum-utils
$ cd /root/rpms/yum-utils
$ rpm -Uvh --replacepkgs *rpm

Docker를 위한 레포지토리 설정
"yum-config-manager" 도구를 이용하여 Docker를 위한 레포지토리를 추가합니다.
$ yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
Loaded plugins: fastestmirror
adding repo from: https://download.docker.com/linux/centos/docker-ce.repo
grabbing file https://download.docker.com/linux/centos/docker-ce.repo to /etc/yum.repos.d/docker-ce.repo
repo saved to /etc/yum.repos.d/docker-ce.repo
위와 같이 Docker를 위한 레포지토리가 추가되면, Docker rpm 패키지 파일들을 다운로드 받을 수 있습니다.
Docker rpm 패키지 파일 다운로드
Docker를 위한 레포지토리 추가 후, 다음과 같이 Docker rpm 패키지 파일들을 다운로드 받습니다.
$ yum install docker-ce docker-ce-cli containerd.io --downloadonly --downloaddir=/root/rpms/docker-19.03.2-3

Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
