centos docker build.

This helps you build CentOS docker image from ISO files like CentOS-6.5-x86_64-bin-DVD1.iso.

The idea is from base-image-docker.

How to use

1. Download iso file from centos vault
2. Run script build.sh. sudo sh ./build.sh CentOS-6.5-x86_64-bin-DVD1.iso.
3. If step 2 is success, then you get layer.tgz file.
4. Create docker image. sudo cat layer.tgz | docker import - centos6.5.
5. Run docker:sudo docker run --rm -ti centos6.5 /bin/bash.

The build.sh create tmnt and target directory.

tmnt is used for temp mount. target is an chroot filesystem. After success, You can delete both. You also can play target with chroot command, like chroot target /bin/bash.

DIY

Change chroot.sh script, to choose RPM packages which you need.
