How to wrap all traffic in VPN using Docker?

Question

Asterisk

I have a running docker container:

[email protected]:~# docker ps                                                                                                                             
CONTAINER ID        IMAGE                     COMMAND             CREATED             STATUS              PORTS               NAMES                     
8b9a7444418e        voipnovatos/asterisk-13   "/root/config.sh"   9 hours ago         Up 9 hours                              asterisk

Launched it with this command:

[email protected]:~# docker run --name=asterisk -v /root/asterisk:/etc/asterisk -d -t --net=host voipnovatos/asterisk-13

Now, apparently, I can run another container on which there will be a separate openvpn server. How?
I haven't started vpn yet. My asterisk is being attacked, fail2ban can’t cope, and I don’t want to watch tcpdump and manually add rules to all iptables. I decided to hide asterisk behind vpn. Of course, I could set up vpn on the host itself, but I thought, because it can probably be made into a separate container

Answer 1

I dashed off in the evening, here is the link , there is also a brief instruction in the readme. If necessary, I will describe in Russian, but not today.

Answer 2

Use docker compose!
