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,

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.
