[Usecase] RepoSync

[Le-Syl21]

We use an Ubuntu LTS with Docker to have repository proxy using Sonatype Nexus3

For some distro (RHEL) we want to keep every installable package other times even if not anymore online.

We can do a reposync but :
1/ I don't want to consume both time some space
2/ I want everything in the same interface (Nexus3)

Nexus3 don't manage mirrors, so I create a docker redhat-ubi using my Nexus proxy to do a reposync.

It will place all file in my proxy and don't use space twice cause reposync use a nullfs ;-)

To do that you need nullfs loaded on the host (Ubuntu) and docker --privileged for container can use mount

Thx again for your amazing work
