Uploaded images do not persist across restarts

[apanagio]

If you stop and restart nautobot instance, you cannot view the uploaded images

Way to reproduce

• Start nautobot using docker-compose
• Upload an image to a site
• Restart nautobot
• Notice the previously uploaded files are missing

Explanation

If I understand correctly this happens because the uploaded images are stored in the file system within the container and the filesystem is purged when the container stops

Proposed Fix

Mount a volume from the host system to store uploaded files

@apanagio do you have a proposed standard of where to mount the volumes back to on the host? I feel like that may be something that we can add on via documentation unless we have a standard to adhere to?

[apanagio]

I don't have a proposal based on standards. I would suggest to do it as it is done with the "db_data" volume for the "db" service.

I did set

    volumes:
    - nautobot-media-files:/opt/nautobot/media

in docker-compose.override.yml for the "main" nautobot service

@EdificomSA how did you set up your permissions so that the nautobot user can write to that volume? I'm getting the following while trying to stand up Nautobot v1.6.2:

Traceback (most recent call last):
  File "/usr/local/lib/python3.10/site-packages/nautobot/core/runner/runner.py", line 117, in settings_callback

Yeah you might need to chown the folder in the named volume, look at :
