종속성 문제 없이 최신 Docker 버전을 설치하는 방법

rhel 7.5 버전에 docker를 설치하기 위해 다음과 같은 내용을 준비합니다.

(목록에서https://download.docker.com/linux/centos/7/x86_64/stable/Packages/), 그리고 최신 정보만

curl https://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-19.03.8-3.el7.x86_64.rpm -o docker.rpm
curl http://mirror.centos.org/centos/7.3.1611/extras/x86_64/Packages/docker-ce-selinux-17.03.3.ce-1.el7.noarch.rpm -o containerselinux.rpm
curl http://mirror.centos.org/centos/7.3.1611/extras/x86_64/Packages/docker-ce-cli-19.03.8-3.el7.x86_64.rpm     -o docker-ce-cli.rpm
curl http://mirror.centos.org/centos/7.3.1611/extras/x86_64/Packages/containerd.io-1.2.6-3.3.el7.x86_64.rpm        -o containerd.io.rpm

파일은 다음과 같습니다

-rw-r--r--  1 root      root       25697324 May  8 13:17 docker.rpm
-rw-r--r--  1 root      root           7793 May  8 13:18 containerselinux.rpm
-rw-r--r--  1 root      root           7793 May  8 13:21 docker-ce-cli.rpm
-rw-r--r--  1 root      root           7793 May  8 13:24 containerd.io.rpm

우리가 그것들을 모두 설치하고 싶은 것은 아닙니다

     You could try using --skip-broken to work around the problem

We  not understand why we get 

    Requires: docker-ce-cli
    Requires: containerd.io >= 1.2.2-3
    Requires: container-selinux >= 2:2.74

최신 버전을 설치했기 때문에

두번째

우리도 얻습니다

Cannot open: docker-ce-cli.rpm. Skipping.
Cannot open: containerselinux.rpm. Skipping.

그런데 내 곱슬머리는 어떻게 된 걸까요?

이 문제를 해결하고 올바른 URL을 설정한 후에도 여전히 다음과 같은 결과가 나타납니다.
