I have just pulled the Prefect image from Dockerhub : https://hub.docker.com/r/prefecthq/prefect

and trying to run it first, am i missing something, please help

Yes, You are right, first I need to run a Prefect server in Docker

I want to run a prefect flow using the Docker , unable to find the right documentation

Here’s the relevant doc

prefect backend server

prefect server start

How are you managing your python dependencies?

pip

conda

etc

prefect version 0.11.5

done

Now try:

prefect backend server

prefect server start

prefect backend server Backend switched to server

My end goal is to run Prefect on AWS ECS

so wanted to try the docker way first

You are awesome @Dylan

😄

Should be a great place to start!

OK i create the test.py using the code :

import prefect
from prefect import task, Flow

@task
def hello_task():
    logger = prefect.context.get("logger")
    <http://logger.info|logger.info>("Hello, Cloud!")

flow = Flow("hello-flow", tasks=[hello_task])

how do i run it please

Including registering the Flow with your Prefect Server backend

But the simplest should be by navigating to the Flow’s page in the Prefect Server UI and pressing the

Run

button

😞

all in the same ipython session

Prefect is designed so that you can run your flow on your laptop using only python

for testing / experimenting

but i was unable to deploy the Prefect on AWS ECS.. do you have any reference link please

My task is to deploy it on the cloud using ECS< the dev team needs to use it for setup

ipython -i test.py  Python 3.8.3 (default, May 27 2020, 20:53:50)  Type 'copyright', 'credits' or 'license' for more information IPython 7.15.0 -- An enhanced Interactive Python. Type '?' for help. --------------------------------------------------------------------------- ModuleNotFoundError            Traceback (most recent call last) ~/prefect/test.py in <module> ----> 1 import prefect    2 from prefect import task, Flow    3     4 @task    5 def hello_task(): ModuleNotFoundError: No module named 'prefect'

If you need to do some quick experimentation with Prefect before you dive in to creating new infrastructure, Prefect Cloud has a free tier

Sure will check Prefect cloud as well

thanks to Cloud’s Hybrid Model, we never see any of your flow code or data

That all stays on your infrastructure

Sounds Great

what could be wrong

my prefect server is running

Are you using pip or conda?

try

brew uninstall ipython

Thanks Dylan

it finally worked

Awesome!
