I’m trying to start up an ECS Agent (with the agent runner token) and getting the following error:

ERROR - proteograph-ecs-agent | Failed to infer default networkConfiguration, please explicitly configure using

--run-task-kwargs`` with the most recent prefect version. I’ve run it successfully with other ec2 instances so i’m not sure what’s going on

Hello Hugo. Could you please check if you have default VPC in the region you are starting your ECS agent?

Ah, I am not using the default VPC

You would pass it like this:

RUN_CONFIG = ECSRun(labels=["test"], run_task_kwargs={
    "networkConfiguration": {
        "awsvpcConfiguration": {
            "assignPublicIp": "ENABLED",
            "subnets": ["subnet-123"],
            "securityGroups": ["sg-123"],
        }
    }
})
with Flow("test", run_config=RUN_CONFIG) as flow:
    ...

sorry, I am not trying to instantiate a ECSRun. I am trying to start the ECS Agent with

prefect agent ecs start

You could specify it in run config or agent. If you prefer using agent you could do following:

prefect agent ecs start --run-task-kwargs <path to a yaml file with network configuration>

And your file with network configuration will look like:

networkConfiguration:
  awsvpcConfiguration:
    subnets:
      - 'subnet-123'
    securityGroups:
      - 'sg-123'
    assignPublicIp: 'ENABLED'

Ah, I see. Thank you!
