local repo not serving all packages on RHEL 8 type OS - repository

Question

I host packages locally for my servers and have done so successfully up to RHEL 8. I built custom nginx packages but when I try install them with dnf they are not found. Some packages are found though.
In this example I use Alma Linux 8.5 but the same occurred on Centos 8.5 too.
Here is my config:
/etc/yum.repos.d/local.repo
[local_el]
name=local_el
metadata_expire=-1
enabled=1
gpgcheck=0
baseurl=file:///opt/devops/packages/
Location to repo
[root#alma8 packages]# ll

When I search with dnf I only get this package from all the others above:
# dnf repository-packages Doxim_el list

Available Packages
nginx-mod-security.x86_64 1:1.20.2-1.el8 local_el
nginx-mod-security-debuginfo.x86_64 1:1.20.2-1.el8 local_el
I tried running createrepo with various switches like --compatibility but that makes no difference. I've disabled selinux on this test box too. I'm not checking gpg.
I also split the files into noarch and x86_64 directories to no avail.
Any assistance will be appreciated. On my older servers using Centos 7 this just works.

Answer 1

The long of it is that some packages are provides in/with modules in rHEL 8+. So you need to consider that and add
module_hotfixes=1
to your local repo's config file to allow your local packages to overwrite a module.
