Tested in the full-root image, creating the container with the Cloud Console, Terraform and the CLI, it seems environment variables do not show up:

root@localhost:~# python3
Python 3.12.3 (main, Aug 14 2025, 17:47:21) [GCC 13.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> os.environ["FOO"]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<frozen os>", line 685, in __getitem__
KeyError: 'FOO'
>>> exit()
root@localhost:~# echo $FOO
root@localhost:~#
Conversely, testing with this small image I made and environment variables seem to appear.
