Hi I am trying to get Prefect Cloud to work with my ECS cluster. I have defined my cluster and task with cdk, and the Dockerfile I am using is:

FROM prefecthq/prefect:2-python3.11

RUN ["pip", "install", "prefect-aws"]

CMD ["prefect","worker","start","--pool","my-ecs-pool","--type","ecs"]

I can run deployments using this task but the ALB health check is failing. I then ran the docker container locally and tried to test the health check with

curl -f <http://localhost/>

and got an error

Failed to connect to localhost port 80 after 0 ms: Couldn't connect to server

. How can I get the health check to pass?

IIRC you can configure the ‘health check grace period’ to be more lenient. Looks like it’s health checking immediately
