docker-compose file version 3.0

[noahtrilling]

This is a great project!

I'm just curious if there is a functional reason why the tutorial hasn't been updated to specify version 3 of the docker-compose files. I was able to remove the 'gateway' configuration of the credentials network (no longer honored in v3 of docker-compose) and the local container endpoint continued to vend my ECS task credentials perfectly. I was curious if other use cases aren't supported by the new docker-compose configuration schema or if the documentation is simply behind.

Thanks!

@noah-trilling All use cases will work with V3 Compose syntax.

The docker-compose files do not work "as-is" with version 3.
The first error that one will run into is documented here: docker/compose#4366

Seeing the same thing here trying to configure a local ECS + fargate setup. Here's the section in the v3 compose documentation that mentions gateway is currently only supported on v2 - https://docs.docker.com/compose/compose-file/#enable_ipv6

Additional IPAM configurations, such as gateway, are only honored for version 2 at the moment.
