Hosting Dockerized website on VPS with Apache - Lemmy.wtf

I made a Docker container of a website that’s difficult to deploy, and I can reliably deploy it on localhost on my personal machine. The container sets up an Apache server with all the files and config to run the website. However, the story is different on my VPS running Ubuntu and Apache. I have two other websites running on the same VPS, each with different domains, and when I deploy the dockerized website I can’t access that site. I opened ports on UFW. The Docker container sets the site to run on port 8000, and I tried running a reverse proxy on just that site with Apache by defining a config pointing towards the internal Docker IP on port 8000, but no luck. Now I’m thinking of running a reverse proxy, but I haven’t found any guides covering my situation: routing websites on both the host machine and through Docker. nginx-proxy [https://github.com/nginx-proxy/nginx-proxy] looks to cover only Docker containers, and the Apache reverse proxy couldn’t access the Docker container. What are my options here? I plan to dockerize everything eventually, but that will be sometime in the future and not right away.
