i have created a docker worker on a server and trying to run my private docker image, but this error occues as it could not fetch docker image due to docker not able to login to registry.

Hi all! I was wondering how we can change the UI port from 8080 to something else. I have changed the

PREFECT__SERVER__UI__PORT

and

PREFECT__SERVER__UI__HOST_PORT

to try and follow the config.toml, but the UI service is still launching and saying “👾👾👾 UI running at localhost:8080 👾👾👾” and I dont know what else to change in the UI service 😞 As a follow up, what is the difference between the UI port and the UI host port? EDIT: I see echo

UI running at localhost:8080

is hardcoded in ./start_server.sh in the UI service, is this meant to be the case?

Does the latest prefect version have any issues for others? My pipelines are all failing about a prefect dependency, griffe, not having a dataclasses module.

Hello everyone, there's a way to configure Prefect so he can use a proxy server? I'm trying to log in on Prefect cloud (using the CLI), but I'm receiving the following SSLError:

requests.exceptions.SSLError: HTTPSConnectionPool(host='<http://api.prefect.io|api.prefect.io>', port=443): Max retries exceeded with url: / (Caused by SSLError(SSLEOFError(8, 'EOF occurred in violation of protocol (_ssl.c:852)'),))

How should web applications (Node.js) listen/subscribe to Prefect workflows completion? I have a task that trains a deep learning model through a Web Application. The “*Start training*” button on the web app sends a

POST /model

REST API call to the Node.js server which then in turn calls Prefect 2.0 using the REST API to start a new run (of an existing deployment). The workflow will train the model, run inference on some data and then persist the output to a database. This is obviously an asynchronous operation that may take a few minutes (or more) to complete. Assuming the workflow succeeded, I would like to notify the users (those who have Chrome opened to my web app) that something has happened, i.e. training completed. How should the Node.js be notified when the flow has finished (either successfully / failed)? Is there like a middleware / RabbitMQ / other message queue that the Node.js app can subscribe to, onto which Prefect publishes event? If not, does Prefect expose other broadcast events? And if not, should I poll periodically from my app and maintain state diff? Thanks!

Hey guys, I'm kinda struggling to set up a Prefect on our company server. So it's running and all that, but I had to setup a reverse proxy (Nginx) as well, so that people can access the UI via standard https at 443 and at a company subdomain (internal that is). The UI itself is accessible, but it's trying to make REST API requests to http://127.0.0.1/api/something which is obviously not working. Is there any env setting I can use to make it understand it should use https://prefect.internal.company.com/api instead? I couldn't find anything on that topic anywhere 😞 Thanks!

Hello! How do I access the string value in a Parameter object? I'm passing a string Parameter to a flow throw the CLI as

prefect run --watch --id flowId --param strparam="paramValue"

. Then in the flow.py file, I am initializing outside the flow

strparam = Parameter("strparam", default "hello")

but I'm unable to access

"paramValue"

. Prefect only sees this

<Parameter: strparam>

Hello friends! I am running into some issues using an ECSCluster with the DaskExecutor. A brief overview of my setup: using Prefect cloud tied in with AWS infrastructure (e.g. running prefect-agent as a service on an ECSCluster) A flow might look something like this:

file_list = ['./file_1.txt', './file_2.txt', './file_3.txt', './file_4.txt', './file_5.txt', './file_6.txt', './file_7.txt', ..., './file_100.txt']

@task
def test_task(input_file):
    result = some_function(input_file)
    return result

def ecs_cluster(n_workers=4):
    """Start a ecs cluster using the same image as the flow run"""
    return ECSCluster(
        n_workers=n_workers, image=prefect.context.image, region_name="us-east-1"
    )


with Flow(
    "test flow",
    storage=S3(bucket="storage"),
    run_config=ECSRun(task_definition=task_definition),
) as flow:
    test_task.map(input_file=file_list)

flow.executor = DaskExecutor(
    cluster_class=ecs_cluster, cluster_kwargs={"n_workers": 10}
)

hello, I struggle with the new projects feature and couldn't find any detailed example for dockerized deployments, nor any list of parameters needed/accepted in prefect.yaml and deployment.yaml. I have deployed a flow with

prefect deployment build

and I am now trying to migrate to projects to create flows as docker images, but

prefect deploy

fails, details in thread

I try to use my minio block storage (s3 bucket) in prefect 2.0? Anyone here knows how to set this up?
