"make docker_makemigrations" not working.

[LuizDMM]

Describe the bug I just created a project, created the .env and local.py files, ran when I run the command make docker_makemigrations it simply don't work. I'm getting a permission denied:

I followed the steps but could not reproduce the error: https://asciinema.org/a/nVbubarq02As0JdiO2Ghmya6u

Not sure what could be causing the permission error.
Do you use sudo docker or just docker? Can you confirm your user has permissions over /home/user/app/?

[LuizDMM]

Hey Vitor, how are you doing? I generally use just docker. Are you asking about the user inside the container right?

Edit: It seems my user has all necessary permissions in /app/:

But when I try to create a file in /app/backend/users/migrations, I'm getting:

I really don't know why this is happening.

[LuizDMM]

Update: Somehow I fixed this running chmod 777 -R .. @rangelfinal Do you think is there any security risk in doing so?

[rangelfinal]

It seems that your backend/users/migrations directory was owned by root - not sure how that would happen, django-admin startproject should create the files using your current user A better option than chmod 777 would be changing the owner with chown $USER:$USER -R .

[LuizDMM]

Maybe there's something with my virtual env. I use pyenv to manage my virtual envs. I will recreate the project changing the ownership of the files then. Thank you very much Vitor.

Hello, and thank you for initiating this discussion. @rangelfinal @LuizDMM

I'm encountering a similar issue where Docker containers, by default, create files under the root user (uid=0) on Linux. To address this, I attempted to pass my user ID and group ID to Docker during the image and container build process. Specifically, I set the user ID and group ID in the docker-compose.yaml (user: 1000:1000), and also tried passing UID and GID directly to the docker-compose command.

Despite these efforts, I was unable to run makemigrations successfully without resorting to sudo. This is puzzling and quite time-consuming, and I'm still trying to resolve it. For now, my temporary workaround has been to use sudo for makemigrations or "chmod 777 -R backend/users/migrations", although I'm aware this isn't ideal.

I've spent a significant amount of time on this issue and need to pivot back to coding, but I plan to revisit this problem soon. Any insights or suggestions would be greatly appreciated.

The two more consistent approaches that I found was 1 and 2

PS.: I am using Bookworm too (Debian 12).

Thanks, I will re-open the issue for now.
