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 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.

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! Just wondering if you found a solution to your issue in the end? I’m wanting to run a TURN server from a docker image which also needs multiple ports exposed to meet standard behaviour… GCP only exposes on port as well which very much limits what we can do there… hoping Digital Ocean might have a better solution… cheers :)

Hi there,

There was a similar question regarding the DigitalOcean App Platform here:

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:

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:

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.
