Yes.

Guix install, shell or pull. And yes, some are stopped but some (for
instance elasticsearch) still run.

As follows:
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS
PORTS NAMES
$ docker run -d postgres:10.10
..
2b52ee072b1f5584cae597afb033cdcc0e560bbe9145b17b41502c204034e60b
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS
PORTS NAMES
2b52ee072b1f postgres:10.10 "docker-entrypoint.s…" 2 seconds ago Up 1
seconds 5432/tcp blah_blah
$ guix shell xeyes -- xeyes

$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS
PORTS NAMES
$ exit
First we see no docker containers are running, then we start postgres-10
from docker hub, now we see its container is running, then we do
something using guix-shell on an application *not already available on
this system*, now the container died. This does not work the second
time when the "derivation" is already "built".
Weird huh?
