We need a system to run the tool and copy the data to all proxies.
I would like to see a new MirrorManager database user who can only do
selects as that is all we need.
Currently we copy the files via SSH to the proxies, if we continue doing
it that way, then we would also need the existing SSH key to copy the
data to the proxies.
Easiest would probably be a small Fedora 32 based VM with 2GB of memory.
I'm not sure f32 will work with 2gb memory anymore. I dont think it
installs at any rate.
I do like the idea of just making it an openshift pod. Perhaps this
could even fit with pingous 'toddlers' setup. ie:
* listen for message saying a repo has updated
* update the db
* create the protobuf
* push out to proxies
The only weird part of putting it in openshift is that we would need to
have fedora_ftp (ro) there available as a volume, but that is doable...
