On a terminal:
docker-compose up
On another terminal:
-
Create a new task
curl -X POST https://localhost:5555/longtask # task id returned
-
Check the task status
curl -X GET https://localhost:5555/status/<task_id>
Experiments:
- attempt to create (almost) concurrently N tasks, N > C, where C is the Celery "concurrency" specified in docker-compose.yml. Check the status of the queued tasks.
- exec into the worker container, and check the celery processes. Verify they are equal to the specified concurrency
