Hey Bone Baboon!
It is not 100% clear from your message how do you want to build a docker
image. I'm assuming that you want to use standard docker tooling and
you want to have docker daemon on YOUR system. Correct me I'm wrong
here.
Dockder service is one of the services that extends
shepherd-root-service-type. They form dependency graph which is
different from extension graph you might have red in guix manual. Each
shepherd service has "provision" field that defines list of simbols that
it provides and "requirement" field (defaulting to '()) that defines
which services it requeres to run. Shepherd uses this information to
spawn services in right order. But in your case procedure
assert-valid-graph (found in guix) warned you that graph is invalid
instead of producing shepherd configuration that will fail when you will
boot.
So. You need a service that provisionts 'networking! You should
probably just use %desktop-services service list like so in your
config. It contains bunch of services you normaly need including
network-manager-service.
(operating-system
...
(services
(append
(list
;; list of your services goes here
(service xfce-desktop-service-type) ;; your wm of choice
(service docker-service-type)) ;; docker daemon
%desktop-services)))

Note also that you dont need to add packages to system configuration to
use them. You could just install it for your user profile.
But there are other ways to build docker images on guix like
guix system vm docker-image yourconf.scm
or
guix pack -f docker -S /bin=bin
Check out info manual for these comands in guix if you havent yet :)
