My word press app is working within a docker container with host port 8080 bound to the web container 80. I am able to access the app using the public IP with port 8080 (41.111.20.36:8080), but the app cannot be accessed using the only IP (41.111.20.36). Secondly, I have pointed my custom domain to digital servers and have matched the droplet and the domain name, I have even created a cname record pointing to that custom domain. But I am unable to access my application using the domain name, and I am unable to access it using the domainename:8080… I assume I should be able to access the web container with only the domain name… Am I missing something? Even inside the server, curl localhost triggers an error with the message, the server refused connection on port 80… but curl localhost:8080 works fine. Any suggestions?

Hi!
DNS only handles domain -> IP mapping. It cannot map the default port (80) to a custom port–you will have to use a reverse proxy for that. nginx is one of the most popular reverse proxies that are used to do that.
First, add a DNS record for your subdomain.
Then, install nginx:
Add a new server block:
Finally, enable it and restart nginx:
You should now be able to browse to http://myapp.domain.com and see the contents of http://your droplet’s ip:8080.
How can I do that without nginx? With .htaccess for instance?
If it says that there is IP not found, could this be a problem with the configuration of nginx or is this because of DNS configuration.
