My company has a mail server which is only available to our local network, i.e mail.example.com => 172.18.0.3. Because docker will create a private subnet for containers, even though mail.example.com can still be resolved to 172.18.0.3 inside the container, that IP address can’t be reached.
I’m looking for a way to do this:
- Using docker-compose configuration only if possible
- Still using bridge network
