Hi all. I am trying to setup ECS agent to run flows in Fargate. Assuming that I have an ECS Fargate cluster ready, here is how I start my agent

from prefect.agent.ecs import ECSAgent

agent = ECSAgent(
    name='Test Agent',
    region_name='eu-west-1',
    cluster='my-test-cluster',
    launch_type='FARGATE',
    run_task_kwargs_path='./config.yaml'
)
agent.start()

This then failed with the following message

[2021-05-14 12:46:54,069] ERROR - Test Agent | Failed to infer default networkConfiguration, please explicitly configure using `--run-task-kwargs`
Traceback (most recent call last):

    ] = self.infer_network_configuration()
  File "/opt/homebrew/Caskroom/miniforge/base/envs/zoined/lib/python3.9/site-packages/prefect/agent/ecs/agent.py", line 274, in infer_network_configuration

@Kha Nguyen 2 secs!

I got it working, I supplied the yaml network config like this

networkConfiguration:
  awsvpcConfiguration:
    assignPublicIP: ENABLE
    subnets: ["subnet1", "subnet2"]

Ahh okay!

Thanks Ciaran 🙂

No worries, glad you got it working!
