Hi all - I'm trying to use the optuna plugin for flyte, and I'm having trouble running the example remotely. I'm running

flyte-binary

on K8s. I

pyflyte register

the eager task specified in the docs, and attempt to run it with

pyflyte --remote run

. I then hit the following error almost immediately:

FlyteSystemUnavailableException: Flyte cluster is currently unavailable. Please make sure the cluster is up and running.

I've tried specifying the

remote

section of the eager task in a variety of ways but no dice. I'd really appreciate some help with this 🙏

What have you tried to set the config?

I've boiled down my problem to this snippet. I can't set the endpoint correctly in the

FlyteRemote

for eager workflows. I've tried the below code, along with various combinations of

FlyteRemote.auto

,

Config.auto

, specifying a config file instead of the endpoint, ... No matter what I do, it always tries to use the default endpoint of

localhost:30080

and fails since that isn't the right endpoint.

from flytekit import eager
from flytekit.remote import FlyteRemote
from flytekit.configuration import Config, PlatformConfig
from flytekit import task

remote = FlyteRemote(
    # config=Config.for_endpoint(endpoint="dns:///calpha-service-flyte-grpc:8089", insecure=True),
    config=Config(
        platform=PlatformConfig(
            endpoint="dns:///calpha-service-flyte-grpc:8089", insecure=True, insecure_skip_verify=True
        )
    ),
    default_project="flytesnacks",
    default_domain="development",
)


@task
async def add_one(x: int) -> int:
    import time

    time.sleep(5)
    return x + 1


@eager(remote=remote)
async def my_test() -> str:
    y = await add_one(5)
    return "hello" + str(y)

@eager(remote=remote)
async def my_test() -> str:
    import os
    print (os.environ)
    y = await add_one(5)
    return "hello" + str(y)

Can you do this? I think you may be right...

Sure thing - one sec

Do you see this in the logs?

Thanks so much! I set the endpoint and now I'm hitting a different error, which means progress 😄 It's a DNS resolution failed now
