Permission error when running startup

[dzx-dzx]

I'm trying to set up the project with make nb command when this appears:

Other issues suggest chmoding the folder to 777, but that doesn't sound safe... I wonder if there is any other solution?

You'll want to chown ``whoami`` .prom_cache matching the user that's running docker, which might be root or your local user.

[dzx-dzx]

the user that's running docker

Can I know exactly who that is by injecting some code?

[dzx-dzx]

I run

docker exec -it newsblur_web echo ```id -u```

Before the migration command docker exec -it newsblur_web ./manage.py migrate which caused the problem, and it returns the id that is the same as my user's, does that mean the following commands are run with my identity?
