I’m curious too. Given the current design that all waypoint-entrypoints connect to the server through an external LB, it’s required for every container to have Internet access. For me on ECS on EC2, that meant provisioning a NAT gateway, and that’s not exactly trivial.
Not to mention, ALBs are not free. Just running idle, they’re $16 a month (us-west-2). If you create one per deployment per app per environment, that’s a non-trivial overhead eventually.
