The docker-compose.override runs command: /start-reload.sh, it most be already on the image from where the backend is build tiangolo/uvicorn-gunicorn-fastapi:python3.10 |

the Dockerfile runs uvicorn main:app --reload when importing the Dockerfile from FROM tiangolo/uvicorn-gunicorn-fastapi:python3.10 however `COPY ./app /app/app takes place till the end here . How is unicorn being executed without the app? does this mean CMD at the end of tiangolo/uvicorn-gunicorn-fastapi:python3.10 is somehow delayed? I see that docker-compose.override.yml has however I can't understand how does docker-compose.yml work in production |

The Dockerfile just have instructions tu build an image, copy the files, install necessary packages on the image...doesn't run or execute the container. To run a single container from an image you would use the command docker run [image]... but docker compose let you build multiple images from different Dockerfiles and then run the containers for each image. If you run "docker compose up -d" and then "docker compose exec backend batch" you can cd and explore the files inside the container and your will find start-reload.sh which executes uvicorn once the backend container is running. |

I have made a similar setup for backend without using docker. async sqlalchemy + pydantic schemas (without sqlmodels) are used there though. |
