1. RHEL

2. CentOS

3. RPM

4. rpmbuild

TL;DR can loot linux softwares here.

How?

Most better with Docker. Feed it the blessed +2 trendy dockerfile, get an image, run a container from it. RTFM! (srsly)

LMDTFY:

                    [docker build]               [docker run -it]
rpmbuild.dockerfile --------------> {image hash} ----------------> {centos shell}
                                                                       |
                                                                       |
                                                 thing.spec ----> $ rpmbuild
                                                                       |
                                                                       V
                                                                   thing.rpm

And then, an installable RPM appears. Nice huh!
