How I can expose extra ports in my digital ocean docker container?

Good Day! I deployed docker container used service “APP - > Docker Hub” (not a droplet). For image I used https://hub.docker.com/r/linuxserver/code-server with code-server.

When I was configuring container, I could expose only one port - port 8443. I wanna use that container for remoute web development. And I need some open ports like 3000, 5000 and etc.

When I deployed that image on my own local docker server I used docker-compose file, where added neccesary extra ports

ports: - 8443:8443 - 3000:3000 - 8000:8000 - 5000:5000

I search for answer on a forum, and found only that. https://www.digitalocean.com/community/questions/how-do-i-update-the-do-docker-droplet-to-enable-ports-80-and-443

But there is a little bit something else.

1)How I can expose extra ports in my digital ocean docker container? 2)Or I have to deploy droplet, install there docker and deploy my yaml docker-compose file 3)Or I have to deploy droplet and install there code-server directly. 4)And why in the marketplace isn’t pre-built Droplet image with a code-server? Or may be I could not find that one.
