The main task of the App is to search for hotels and book rooms.
The uvicorn web server is used to run FastAPI. The command to run looks like this:
uvicorn app.main:app --reload
It must be run on the command line, always being in the root directory of the project.
To start Celery use the command
celery --app=app.tasks.celery:celery worker -l INFO -P solo
Note that -P solo is only used on Windows, as Celery has problems working on Windows.
To start Flower use the command
celery --app=app.tasks.celery:celery flower
To run a web server (FastAPI) inside a container, you need to uncomment the code inside the Dockerfile and have an already running PostgreSQL instance on your machine.
Command to run Dockerfile:
docker build .
The command is also run from the root directory where the Dockerfile resides.
To start all services (DB, Redis, Web Server (FastAPI), Celery, Flower, Grafana, Prometheus), you need to use the docker-compose.yaml file and the commands
docker compose build
docker compose up
Moreover, the build command needs to be run only if you changed something inside the Dockerfile, that is, you changed the logic for compiling the image.
