Hi new to prefect I’m curious if V2 is actually production ready? I can tell at least from the UI there are a lots of features are missing like creating a flow run etc. If this is my first time setting it up is it better to start off with V1 first?

Prefect 2.0 is production ready since the GA launch. To trigger a flow run from the UI:

Thanks but looks like the UI is very limited? for example in V1 you can create with specifying parameters
I’m also very confused with the agent. I can see in V1 I can run my agent in K8S but there is no such an option in V2?

Replying here as well since I’d like to track any follow-up on this inquiry. Creating a flow run with parameters from the UI is on our “to figure out” list as well with Prefect 2.0.

you can modify parameters on your deployment, or you can even trigger it locally from Python with different parameters - here changing Marvin to Marty: 
from prefect import task, flow
from prefect import get_run_logger


@task
def say_hi(user_name: str):
    logger = get_run_logger()
    <http://logger.info|logger.info>("Hello from Prefect 2.0, %s!", user_name)


@flow
def parametrized_flow(user: str = "Marvin"):
    say_hi(user)


if __name__ == "__main__":
    parametrized_flow(user="Marty")

Cool thanks Anna. I notice this works for local runs but trying to figure out how to override parameters for a deployment. I found the open issue on Github for the UI so it looks like that’s in progress. I took a stab at using the Python API but it looks like 
create_flow_run_from_deployment()
is not as straightforward as I thought. Currently exploring the API route on this end to see if that’s a workable option for us. 🤓
I was able to override parameters via the Python API on a deployment. 
from prefect.client import OrionClient
import asyncio
prefect_client = OrionClient(api="http://<ip>:4200/api")
loop = asyncio.get_event_loop()
task = loop.create_task(
prefect_client.create_flow_run_from_deployment(
deployment_id="188e210d-4246-45d4-9ac2-014852b96115",
parameters={'content_id':'new_content_id'}))
loop.run_until_complete(task)

Following up here to also ask about the agent status? Is that something that is going to be added to UI soon to see the health of the agents?

Not soon, but certainly at some point this year -- I'm aware it's a very broad estimate but that's the only one I can give for sure at this time
