-- Docker: `docker run -e BK_REBRICKABLE_API_KEY=xxxx`
-- Docker compose (directly in `compose.yaml`):
-
-```
-services:
-  bricktracker:
-    environment:
-      - BK_AUTHENTICATION_KEY=xxxx
-```
-
-- Docker compose (with an environement file, for instance `.env`)
-
-```
--- .env
-BK_AUTHENTICATION_KEY=xxxx
-
--- compose.yaml
-services:
-  bricktracker:
-    env_file: ".env"
-```

-> **Warning**
-> Do not use quotes (", ') around your environment variables.
-> Docker will interpret them has being part of the **value** of the environment variable.

->  bricktracker:
->    environment:
->      - BK_AUTHENTICATION_KEY="xxxx"
-> ```
->
-> ...will make Docker believe that your API key is `"xxxx"`.
