With the following “Docker recipe”, you will set up a Docker node running separate WordPress installation on two domains or subdomains. This setup is pretty much production ready, with:

• nginx reverse proxy by Jason Wilder that automatically routes traffic to new containers that are created with the VIRTUAL_HOST=sub.domain.com environment variable. This nifty container performs a similar function to Traefik or HAProxy, but it is amazingly simple to use.
• letsencrypt-nginx-proxy-companion by Yves Blusseau that obtains an SSL certificate from Let’s Encrypt, the free Certificate Authority, when you specify the LETSENCRYPT_HOST and LETS_ENCRYPT_EMAIL environment variables on any application container (i.e. WordPress) that needs to be served over HTTPS. The companion even pings Let’s Encrypt every 90 days to automatically renew your certificates!
