The terraform support ist also still missing to add this option to your infrastructure as code stack. If you need DinD, you need EC2 hosts for the DinD task, the rest can probably be fargate as long as they dont need access to docker.sock or host files, Use AWSVPC for the EC2 tasks, that way it can easily talk to the fargate tasks which use that networking method, You might be interested in this https://aws.amazon.com/blogs/containers/deploy-applications-on-amazon-ecs-using-docker-compose/, I think I have already been at your shoes.
