Setup

First install hatch

Register Deployments and start a local Prefect server and work-pool by doing:

• hatch shell dev
• prefect server start &
• prefect config set PREFECT_API_URL=http://127.0.0.1:4200/api
• prefect work-pool create local-work-pool --type process
• prefect --no-prompt deploy --prefect-file prefect.yaml --all
• prefect worker start --pool local-work-pool

Run

Trigger a run of the hello-world-deployment. This will in turn trigger multiple other runs of the hello-world* deployments. The trigger of hello-world3 will fail. Look for the: prefect.server.utilities.messaging.memory - Message failed after 4 retries and will be moved to the dead letter queue in the logs from the worker.

Misc

For resetting/clearing the Prefect database do: prefect server database reset -y
