I don't know the exact steps, and I am not aware of upstream
documentation page explaining this.
You will probalby want to use the 'rsync' tool to sync RDO RPM
repositories and create a local repo on you staging machine. Sync
packages, use `createrepo` tool to generate yum/dnf repo metadata. Then
set up a webserver to make the repository available over HTTP. Search
the internets for "Create local RPM repository / mirror", there are many
generic guides that will help you.
For containers you need to set up a local container registry. Then I
would suggest useing the `skopeo` tool to sync containers from the
public registry to your local registry.

You need to set up the undercloud to use the RPM repositries on the
staging server. Put config in /etc/yum.repos.d/*.repo files. Once the
overcloud is deployed you would want to add the repo config there as well.
You need to use a custom containers-prepare file when deploying the
undercloud and overcloud, you must set the namespaces to point to your
local registry. Something like this:
- push_destination: false
I would suggest generating the container prepare env file with the
`openstack tripleo container image prepare` command and then edit the
