Ubuntu updates from a local repository including containers

In larger companies a local repository cache could be a more efficient way to update and install packages.
Providers often have their own repositories as well.
My favorite provider Hetzner runs an own repository:

Servers at Hetzner have the repository pre-setup (it is only available for Hetzner servers).
Container images
But when you use a container image the standard Ubuntu repository is used.
I never looked into it. But now I am working on a project where we require local repositories.
Using a local repository is the more efficient way in this case.
I have added functionality to the container image build use an alternate repository.
But this is limited to Ubuntu LTS 24.04 (Noble) for now.

Building your own local repository
Debmirror is a tool to build repositories. If you only select the main components for x64 the size is 47 GB.

The script syncs the packages and you can use for example NGINX to host the repository.
I have tested the setup with Hetzner and also with the local repository.
Does anyone have a similar requirement? What are you doing to build with a local repository?
