Multiple reachable docker containers on Linode

Hello, I've recently started working with Linode for our organization and have spun up our second Linode.

I have a question about going forward, I have followed this guide:
https://www.linode.com/docs/guides/how-to-self-host-the-bitwarden-rs-password-manager/

on how to run a BitWarden server in a docker container, and was wondering how I can run more services on that Linode, like a messaging app or some other service, and have it accessible from the net.

thanks!
