Docker compose doesn't run in specified AWS region

[JackPriceBurns]

Description of the issue

Docker compose does not respect the AWS region you choose when you make a new docker context for ECS.

--------- *         ecs                 (eu-west-1)

I removed the name of my contexts, but it clearly says eu-west-1

Steps to reproduce the issue

1. Create a new docker context for ECS and specify the region as eu-west-1
2. Run docker context use {your_newly_created_context}
3. Run docker compose up

Furthermore if you specify x-aws-cluster and set it to an ECS cluster in eu-west-1 as the documentation says you can do here it doesn't work and gives you the error InvalidParameterException: Invalid Region in ARN which also indicates that it's operating in the wrong region entirely.

Observed result

All of the infrastructure is created within us-east-1

Expected result

For the infrastructure to be created in eu-west-1

@ndeloof I'm happy with this issue being closed as it's a duplicate.
However, is there actually being something done about this? The other issues seem to be stagnant and nothing seems to be happening about this issue that has been reported by a few people.

Unfortunately my team have actually decided to stop using docker compose due to these issues and some other limitations.
