Since spacewalk does not support Red Hat Enterprise Linux is it possible to use Amazon Linux AMI ( which supports RHEL yum updates ) and use that as a proxy or mirror to re-distribute yum updates? or use Pulp/Katello for RHEL update distribution. There is no information i could find in my google search.
Here is some info i have gathered:
While it is true that Spacewalk does not connect to RHEL repos (otherwise it would compete with Satellite), you can get around it using mrepo to mirror the repos and then upload into Spacewalk. It doesn't get errata, but there is a python script called get-errata.py ( I believe) that will do this for you. They require a little bit of setup,but they work. I know because I used both these tools to maintain the patch (and install) infrastructures of a couple different companies.
Just search for mrepo (plenty of pages and examples). get-errata.py will be a little more work.
