For containers in a task with the bridge network mode, the Amazon ECS agent finds open ports on the host and automatically binds them to the container ports. This ENI is separate from the underlying hosts ENI. The protocol determines what telemetry will be shown in the ECS Console for Service Connect services using this port mapping. If using the EC2 launch type, the allowable network mode depends on the underlying EC2 instance’s operating system. EFS is a storage service supporting Network File System(NFS) protocol. amazon.

If we SSH into the instance and curl the private IP associated to the task ENI, we can access the website running on the container. Each container instance has a default network interface, referred to as a trunk network interface. If you are using Windows EC2 instances, then either default network mode or the awsvpc network mode can work. Today, AWS announced task networking for Amazon ECS, which enables elastic network interfaces to be attached to containers. Amazon ECS creates the ENI and attaches it to the host Amazon EC2 instance with the specified security group.
