docker image for CentOS

Perpose

Make minimum old centos docker image.

Almost same https://raw.githubusercontent.com/moby/moby/master/contrib/mkimage-yum.sh

Difference against original

• use vault.centos.org in /etc/yum.repos.d/CentOS-Base.repo
• No latest images. Latests don't exist in vault.centos.org
  • cf) 6.9 and 7.4.1708 are latest, then no binaries in vault repo in 2018/01
• Actually not minimum. curl and yum-utils are added.

How to use

bash ./prepare.sh
# edit run.sh and yum.conf.d
# no edit, run.sh make centos 4.4 - 8.2 images.
sudo bash ./run.sh
