Just found this project and super excited, works great for the default or other non --internal docker networks.
$ docker run --rm --name nginx -d nginx
$ docker inspect nginx --format '{{.NetworkSettings.IPAddress}}'
172.17.0.2
$ curl -m 1 -I 172.17.0.2
HTTP/1.1 200 OK
Server: nginx/1.23.3

But it doesn't work if I use an --internal network
$ docker network create --internal internal
$ docker run --rm --name nginx-internal -d nginx --network internal
# note that NetworkSettings.IPAddress is empty
$ docker inspect nginx-internal --format '{{.NetworkSettings.Networks.internal.IPAddress}}'
$ curl -m 1 -I 172.28.0.2
curl: (28) Connection timed out after 1002 milliseconds
Was wondering if its even possible for this to work with an internal network?
