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.

Hi there,
There was a similar question regarding the DigitalOcean App Platform here:
https://www.digitalocean.com/community/questions/is-it-possible-to-open-two-external-ports-on-one-app
Kamal answered that it’s currently not possible to expose multiple external ports on a Service. If it works with your setup you could use the same websocket server and put the existing servers under separate path prefixes
Alternatively, you could use a Droplet with Docker installed:
https://marketplace.digitalocean.com/apps/docker
Once you have a Droplet with a Docker installed you can follow the steps from the answer that you’ve shared in order to start a container with multiple exposed ports.
Also, you can follow the steps on how to run code server on your Droplet here:
https://www.digitalocean.com/community/questions/run-vscode-in-browser-from-a-remote-server
As of the time being there is no image with code server on the Marketplace.
Hope that this helps. Regards, Bobby
I had this same problem today. Basically, I need to run the container with -p 9898:9898/udp (notice the UDP).
Please, DO, consider adding the possibility of mapping custom ports in our containers. The App Platform is very convenient for automating deployment; going back to a Droplet feels disheartening now.
