[FIXED] Run Python script in isolation

Issue

I need to run a Python script from within bash in a way so it does not have access to any environment variables or system files/configurations. This due to an AWS boto3 client that tries to read configuration information from the environment and/or a config file.

Searching only results in how to access environment variables.

Is what I am looking for possible, and if so how?

Solution

Run your command with chroot. For example, if you execute

chroot ~/newroot python yourscript.py

and your script tries to access /usr/lib/some_config.txt, it will actually try to open ~/newroot/usr/lib/some_config.txt. As far as your script knows, ~/newroot is the root of the local filesystem.
