Deploying docker and then wordpress, what about DNS ?


So i found some tutorials for deploying docker to ubuntu - actually there is already a one click app for creating a docker image. Once this is done, I have found a tutorial for deploying mariadb and wordpress to the container. Although I am confused about dns ?

Do I need to configure DNS, via nginx or something ?

Anyone have any good examples ?

I was thinking of using an external DNS service. or do you have recommendations, I really dont want to have my own dns server.

Thanks in advance.

Since Docker would be using internal IP addresses, you’d need to proxy incoming requests using NGINX (for example) to the Docker container. You’d simply point an A entry for the domain to the IP of your main Droplet IPv4 IP.

For example, your main IPv4 IP might be and the internal IP for the container may be In such a case, NGINX would accept incoming requests on the IPv4 IP for the Droplet, proxy them to the container IP and the container would handle the request from there.

NGINX (on the Droplet) would be setup to listen on port 80 while the container may be setup to listen on any port that you wish (such as port 8080). The only important step there would be to make sure that NGINX (on the Droplet) is setup to proxy to the correct port on the container.

Your DNS, in such a case, is no different than any other type of setup. You’ll still set the A entry for the domain to the IP of the Droplet and create your www CNAME to match, should you need it.
