사내 발표자료 겸 만들었는데, ECS Fargate를 이용하실 분들이라면, 편리하게 쓰실 수 있도록 최대한 상세하게 만들어 보았습니다. 사실 CloudFormation 등 배포는 좀 더 편리하게 할 수 있지만, 회사 사정도 있고, 제가 일단 그런 기술을 너무 늦게 알았기 때문에 다루지는 않았습니다.

166. Only private subnets are supported for
the awsvpc network mode. Because
tasks do not receive public IP
addresses, a NAT gateway is required
for outbound internet access. Inbound
internet traffic should be routed through
a load balancer.

167. If you are using Fargate tasks, a public
IP address needs to be assigned to the
task's elastic network interface,. The
network interface must have a route to
the internet or a NAT gateway that can
route requests to the internet, for the
task to pull container images.
