Auto Assign Public Ip
DISABLED  
?

Public IP (ENI) 
Private IP (ENI)

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.

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.
