Is docker run --net=host analogous to the “Host” network mode on AWS ECS?
Was following discussions in this article. We want to bring up our Dockerized application in ECS and currently the application run as a standalone docker container using the command
docker run --net=host -d -p PORT:PORT My-APP
The question is - if we migrate to ECS - does this --net-host setting Map to the Host Networking Mode in ECS?

Yes:
If the network mode is
host, the task bypasses Docker's built-in virtual network and maps container ports directly to the EC2 instance's network interface directly. In this mode, you can't run multiple instantiations of the same task on a single container instance when port mappings are used.
