Hey folks :simple_smile:
We are using ECS Agent to execute flows.
Is there a way to apply custom tags to the ECS task that is executed?

<@U019RALEAUW> do you need that for billing purposes? In general, you can add tags to your cluster to which you deploy your ECS agent and all the ECS tasks for your flows deployed to that cluster would inherit those tags.
```aws ecs create-cluster --cluster-name prefectEcsCluster --tags key=team,value=devs```
You can find more details <https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ecs-using-tags.html|here>

Well, we do have the right tags on the cluster.
But for some unknown reason, they are not applied to tasks running on the cluster :sweat_smile:

Correct, this flag seems to be relevant: *--propagateTags*
Keep us posted, it’s an interesting topic. I think in the worst case, maybe you could track the costs just via the ECS cluster provided that all flows are deployed to the same cluster and only to that cluster.

Hey <@U02H1A95XDW> :wave:
I confirm that using `propagateTags` did the trick!
We used this config:
```enableECSManagedTags: true
propagateTags: TASK_DEFINITION```
