Hi,
maybe it’s to late in the evening, but I’m not able to setup a network binding/ip with port, e.g.:
$ docker run -d --rm --name=portainer \
-v data:/data -v /var/run/docker.sock:/var/run/docker.sock \
--net=dmz_net --ip=192.168.90.20 -p 192.168.90.20:8008:9000 \
portainer/portainer
It shall setup on 192.168.90.20 (dmz_net) port 8008 (or even 80, which doesn’t work too).
$ docker inspect portainer

also, netstat doesn’t show anything:
$ sudo netstat -tulpen

but probably I miss something here (I’m new to vlan networking). Nevertheless, I can connect to the default port successfully:
$ curl -I 192.168.90.20:9000

but not from port intended:
$ curl -I 192.168.90.20:8008
curl: (7) Failed to connect to 192.168.90.20 port 8008: Connection refused
The docker network is VLAN:
$ docker inspect dmz_net

So, what went wrong here?
