EPEL 7 builds started to fail due to centos7 EOL URLs

[kokesak]

In several projects we are using the copr for building packages to RHEL7/Centos7 - this now started to fail as the centos-7 reached the EOL.
Full log:

Would it be possible to fix the URLs to point to the vault (https://vault.centos.org/centos/7/) on the build systems instead of the mirrorlist?

IIUIC there is a container image pulled, which has the last update pushed ~ 5 years ago
https://hub.docker.com/r/centos/redis-32-centos7

@praiskup, this seems to be the same issue as https://lists.fedorahosted.org/archives/list/[email protected]/thread/6J2SADUV5SF5I63COQR5HBQNO64IBS2X/.

If a container image needs to be used then this one https://hub.docker.com/r/eurolinux/centos-7 can be used after EuroLinux/containers-rfc#10 is fixed.

Yup, CentOS project is EOL: rpm-software-management/mock#1397

For Copr, it seems pretty easy to keep x86_64 working from vault, but not other architectures.

Jakub promised he'd took a look at this one. Seems that we could/should switch EPEL-7 chroots in Copr to RHEL+EPEL in Copr

Seems that we could/should switch EPEL-7 chroots in Copr to RHEL+EPEL in Copr

Done on both Fedora Copr and Internal Copr. I can now successfully build in EPEL7 chroots, so closing the issue. If needed, please reopen.
