If you a PID from any process that belongs to the container you can
list its mounts by doing /proc/$PID/mountinfo. You can also access its
files through the /proc/$PID/root pseudo directory. 

There's also /usr/lib/systemd/systemd-dissect --mount if you want to
look into a raw image and have it mounted externally just like
systemd-nspawn would do it.
