A microservices demo built with Celery and FastAPI.

Features:

• launch all with one docker-compose up
• services run in isolated docker container
• submit tasks with RESTful API (FastAPI)
• separated task queues
• concurrence control
• tasks monitor

Launch the demo:

docker-compose up

Check the page:

• FastAPI page: http://127.0.0.1:8081/docs
• tasks monitor page (powered by flower): http://127.0.0.1:5555

Note: please change IP address and ports accordingly, they are specified in docker-compose.yaml

Try the demo:

• Request add or multiply services in the FastAPI page and see the interaction process from the log (terminal window of launching docker-compose).
• Request check api with task_id to see the status and the result of the request.
• Check the monitor page to see all submitted tasks.
