Since OP is running on AWS anyway, why not just use Amazon ECS? The orchestration (including Elastic Beanstalk) is pretty good, and we haven't had any stability issues in production with it. Same thing for registries; just use AWS ECR instead.
Here here. I operate hundreds of ECS clusters and it's great.

Amazon has met this challenge with the ECS Optimized AMI. It works, gets frequent upstream updates, and you can open tickets against it and get great support.
