Quoting https://engineering.redhat.com/rt/Ticket/Display.html?id=481468

Hi there,

We are looking for a nexus repository that we could use for some of our
rubygem dependencies.

Could we please have access to repository.jboss.org for the 3scale team?

Please feel free to let me know what info you need from our side and I'll
be happy to provide.

Thanks in advance,
Yorgos
