Hey that's a real nice starting point for a container management tool!
  So maybe there should be a system service to manage containers and
then a 'docker compose'-like tool for declaratively specifying
containers and their network bridging configuration that is a client
of the service?

Agreed!  We could turn Ricardo’s code into ‘container-guest-service’ or
something and have ‘containerized-operating-system’ add it
automatically.

please there was some progress with this service?

once done, could it be possible to declaratively start a whole network
of containers using a dedicated home-service, or
containerized-operating-systems (also on foreign distros)?

right now with "guix system container" we can imperatively manage
(start/stop, connect to the console with nsenter) and connect them
to the network [2], Ricardo showed us how he do it programmatically;
having a declarative interface (os-records) whould be awesome!

I'm very interested and willing to test it, if needed

thanks! Gio'

Does anyone have a simple example of a container with PostgreSQL and some web service like Flask? I'm new to Guix and I did see the PostgreSQL example that is linked in codebook but I'm missing an example of adding a custom service and was a bit overwhelming when I looked at the source code.
