do you absolutely have to explicitly specify an ECS cluster name to an

ECSRun

config or can it not infer the correct cluster from providing agent labels?

I believe it will use a cluster name of

"default"

if it's not provided.

`cluster (str, optional)`: The AWS cluster to use, defaults to

"default"

if not provided.

🤔

Yeah, it an argument to `agent ecs start`: https://docs.prefect.io/api/latest/cli/agent.html#ecs-start

erm… huh, k… our agents are already running on the cluster… not sure where else they would run… I’m talking about flow jobs specifically

It would be nice if the default behavior for the ECS agent was to start flows on the same ECS cluster as the agent was running on. I remember running into this early on.

agreed

if you need more ECS examples, check out this repo e.g. here https://github.com/anna-geller/packaging-prefect-flows/tree/master/flows/ecs_flows_from_5411_pr you don't have to specify cluster name, e.g. here it will be inferred from the agent:

RUN_CONFIG = ECSRun(
    labels=["ecs-agent-local"],
    task_definition_path="<s3://prefectdata/flow_task_definition.yaml>",
)

awesome, thank you! re: inferring cluster, it may be an artifact of the TF config provided
