I have a docker compose running dagster (similar to https://github.com/dagster-io/dagster/tree/master/examples/deploy_ecs) but when I run the job in dagit I get the following error:

Hey Lucas - it looks like this is using the DockerRunLauncher, but the example you listed is in Ecs (and uses the EcsRunLauncher). I wouldn't neccesarily expect the DockerRunLauncher to work out of the box in ECS

Makes sense. But I'm not on ECS, this is running on my local machine

Have you tried the deploy_docker example, does that one work out of the box? https://github.com/dagster-io/dagster/tree/master/examples/deploy_docker

tried the docker example and the new container is not being created, it remains stuck in the "Starting" state

If you run "docker logs <that container ID>" are there any clues?
