Specify BASE_DIR via environment in docker

Describe what you are trying to accomplish and why in non technical terms Hey @blakeblackshear, it would be great if I could specify BASE_DIR from docker environment instead of the hardcoded /media/frigate.

Personally, I just want to use /data/frigate so when I run lsof commands on my host they point to the correct place and lsof wont then show:

frigate.o 26730 root mem REG 0,38 32897 /media/frigate/frigate.db-shm (stat: No such file or directory)

Describe the solution you’d like An environment variable to override the default BASE_DIR:

import os
BASE_DIR = os.environ.get("FRIGATE_BASE_DIR", "/media/frigate")
CLIPS_DIR = f"{BASE_DIR}/clips"
RECORD_DIR = f"{BASE_DIR}/recordings"
CACHE_DIR = "/tmp/cache"
YAML_EXT = (".yaml", ".yml")

Describe alternatives you’ve considered

Possibly you could define the directories in the config file too.

This has other implications since nginx uses the media directory as well. It would require making that config dynamic and today it is statically defined. I am fine leaving this open in case one day it makes sense.

I would still like this ability… thanks 😃
