Give containers that both use the VPN access to each other

hi @DEX3 that is already possible,
try http://172.18.0.1/ or http://172.17.0.1/
you can look for the proper ip using docker network inspect your_network that is the ip for that entire network and you can access other containers exposing ports within the same network using that ip.

also keep in mind that your current OPENVPN_OPTS may not work as you expect, since the servers push some configurations into the client, and may override some of your settings, that's why in my example i have --pull-filter ignore "ping-restart" to ignore the override of the --ping-exit parameter, please read the openvpn documentation for more information

Thanks, that actually works! I'm wondering if there's a nicer way to get access to these IP's? I'm running the container as part of a docker-compose setup, and I don't think there's a way to tell beforehand which IP's will be chosen, is there?

Can I somehow get the correct IP from within the container, without having to docker inspect the network from the outside after it has been created?

[bubuntux]

it depends on your setup, if the containers are using the same network, you should be able to call services from those containers using 127.0.0.1, not sure if there's a nicer way

Well I don't have any special network config in place other than network_mode: service:vpn, which I have set for all of them - so I guess they should be in the same network.

They do not have access via localhost though :/
