Docker DNS setup on VPS

I have a VPS with static IP address (108.1.2.3 for ex). On this server I have a two docker containers with separate IP (10.1.2.3 and 10.1.2.4 for ex). And I have two domains: domain1.com and domain2.com. My question is: how I can setup a DNS server for this two domains? I need to point domain1.com to 10.1.2.3, domain2.com to 10.1.2.4 and have an access through browser for each domain.

I found a solution, but it doesn't work for me.

Unless you add network interfaces to the VPS and give it multiple static IPs and bind the container ports to these IPs (using docker run -p with ip:port:c_port value), you will need some kind of reverse proxy.

When using a reverse proxy such as nginx, your issue with nginx seems to be the need to reload. Please note that, you won't only need to reload every time a new container is launched, but also every time a container is restarted (if you use an nginx container internally linked to the other containers..)

What you need is service discovery and configuration listeners to reload your reverse proxy automatically such as: etcd+confd or https://consul.io/
