Okay, to get the disclaimer out of the way, I understand that SCLo/CentOS 
packages are not supported by RedHat. I'm trying to get my Chef SCL code to 
work on RHEL again (CentOS works great via centos-release-scl). The official 
(from what I can tell) solution is `subscription-manager repos --enable 
rhel-server-rhscl-{6,7}-rpms`. The problem is this fails on most cloud-y RHEL 
installs as the EC2/Rackspace/whatever images don't come with a subscription 
setup and thus even though they (I think, the cloud licenses are weird and 
bespoke) could use the SCL subscription, the system won't allow it.

So, are you're hitting the issue described in 
https://access.redhat.com/solutions/1120983?

Except replace "EC2" with any other provider (Rackspace, Google Cloud, Azure, 
etc).


EC2 has a (custom?) solution for this with a local RHUI server in each region 
that can be used to set up the SCL repository. This server is not reachable 
from outside EC2 though, so doesn't help on other cloud platforms.

It seems like the solution above does work for EC2 but not for other providers, 
right? In any case, I'd recommend to contact RH support, they already might 
have seen issues like this and might have a solution.

Yes, but solving it for EC2 required Amazon to deploy quite a bit of 
infrastructure and modify their base images so I don't think this is likely to 
be a short-term help unless every cloud vendor does the same.

I see. But I don't understand why RHSCL is the problem and RHEL packages are not (or are they?). If the subscription does not work at all, then users are not able to install any packages, not only RHSCL, right? Since RHSCL packages often need something from the base RHEL, would it help at all to install SCL packages "the temporary way"? Or is it just problem of RHSCL channel that is problematic?


The next thing I thought to try is to use the SCLo/CentOS repositories directly 
for cloud users as they probably don't care too much about support or they 
would have set up a subscription. I can't figure out a stable way to do that 
though. From https://github.com/sclorg/centos-release-scl, I can do 
`yum-config-manager 
--add-repo=https://copr.fedoraproject.org/coprs/rhscl/centos-release-scl/repo/epel-7/rhscl-centos-release-scl-epel-7.repo`
 but this only activates the sclo/ repo, not rh/ so I can't install the 
recompiles of the RHSCL packages (i.e. most of them).

The problem I have with this particular solution is that SCLo packages from 
CentOS were never meant to be run on RHEL, nobody tests them on RHEL and simply 
said for RHEL the solution is RHSCL channel. Although I understand you might be 
frustrated by not being able to do it simply the correct way..

This is no longer about correct or incorrect, I just want anything that works.


I could set the http://mirror.centos.org/centos/6/sclo/x86_64/rh/ repository 
manually, but I would need a copy of the GPG to import. I've filed 
https://bugs.centos.org/view.php?id=11468 to request the GPG key be made 
available via centos.org but I would imagine any changes there will take some 
time.

Well, the keys are the same for all SCLo packages on CentOS, so installing centos-release-scl package brings the missing key to the machine.

So with that wall of text, what's the best way to get SCL packages on RedHat 
for _all_ RHEL users?

That's exactly which way we should focus on, but I'm not able to help right 
now, since I don't have enough information about it. I'll try to fill gaps in 
my knowledge, but as mentioned above, I'd recommend to contact the RH support 
with this problem.

How do I contact RH support for something like this?

Creating a support case is generally the first step I guess:
