Hi, do we still have SequentialTaskRunner in any form in Prefect 3.0.0? I couldn't find it, and not specifying task runner shows concurrent behaviour.

@Marvin Is it possible to manually rerun tasks via the prefect UI, How would I do this

Hi! I am working on setting up a simple CI/CD process that registers new flows each time a push is made to main. My folder structure is inspired by the gitlab data team so at the root of my project i have a folder orchestrate. Within that folder i have a folder tasks - within this there are subdirectories that contain custom modules that store tasks we use throughout our flows. While registering flows via the GitHub action, the Prefect CI is complaining about not being able to find a module in the tasks folder. When I run this locally, I do not get any issues. I am pretty sure it is related to my PYTHONPATH setup within the GitHub flow but I have not had any luck troubleshooting. Has anyone out there run into a similar issue?

Hello, I’m new to Prefect and I need some help getting started. I’m currently struggling with two issues: 1. I’m setting up Prefect server on EKS using Helm. After

helm upgrade

ran successfully, I get commands such as

1 Run the following command to get the UI URL:

  UI_HOST=$( \
    kubectl get svc \
    --namespace prefect \
    --template "{{ range (index .status.loadBalancer.ingress 0) }}{{.}}{{ end }}" \
    prefect-server-ui \
  ) \
  && echo "UI available at: http://$UI_HOST:8080"...

when I run the above command, I get an error saying

error: error executing template "{{ range (index .status.loadBalancer.ingress 0) }}{{.}}{{ end }}": template: output:1:10: executing "output" at <index .status.loadBalancer.ingress 0>: error calling index: index of untyped nil

Then I have to run

kubectl port-forward <name of the service> <port>:<port>

to get ui and apollo servers running. Is there a way to run this without port forwarding? 2. I’m trying to run a hello world example flow on prefect server on my EKS cluster. I tried to trigger it from my command line by creating a project and running

prefect register --project test-project -p hello/

. The registering seem to run successfully but I don’t see the flow on the ui. I’m also not able to manually create flow project using ui. Am I interacting with two different prefect engine here? How do I register prefect flow so that it is running on my prefect server on EKS cluster?

Hi all, prefect 2.0. I am getting the following error while building a deployment.

ValueError: Unable to find block document named mini1 for block type RemoteFileSystem

@Marvin how to configure a docker registry credentials using prefect cli?

@Marvin I am using Prefect 3 locally using docker to run the server, and then for each flow, we deplpoy to docker (local). It was working before but now it's not after rebooting my machine. I think it's due to the DOCKER_HOST env variable (whcih is not set currently). I am on MacOS and Docker Desktop is running. Flow deploy co

ctos_monitoring_list_flow.deploy(
            name=config["name"],
            work_pool_name="local-docker-work-pool",
            work_queue_name="ctos-monitoring-list-queue",
            image=DockerImage(
                name="prefecthq/prefect", tag="3-latest", dockerfile="Dockerfile.worker"
            ),
            parameters=config["params"],
            cron=config["schedule"],
            job_variables={"networks": ["dmp_default", "dmp-etl-prefect_default"]},
            push=False,
            build=True,
        )

The above exception was the direct cause of the following exception:

@Marvin Prefect 3, how to name a flow run when it is scheduled, rather than not until it runs

RuntimeError: Timed out while attempting to connect to ephemeral Prefect API server.

Is this a known issue? We wrap controlflow runs via a retriable mechanism, so it eventually completed. But is this potentially something that is on our end?

@Marvin how do I trigger a deployed flow using the prefect SDK using the requests library? give an example that sends flow parameters
