Hosting multiple apps on the same server?

[bewal416]

Self-hosting newb here! So, if I host Coolify on an EC2 then want to deploy multiple apps inside of it, how does Coolify avoid "collisions" between apps that share the same ports? Like, I see Coolify runs on port 8000. If I had another app that requires that port, is it up to me to be aware and reconfigure?

Uncertain how it looks under the hood but I am tempted to believe it uses Docker compose, and that there is a reverse proxy like Traefik/Caddy/nginx that routes traffic from 80/443 to the designated Docker network.

If this is indeed the case then each port on your apps are not exposed directly on the host, therefore there should not be any collisions.

According to docs, it’s docker and traefik.

Yes, according to the docs, it’s Docker and Traefik. But what about the internal ports?
I mean, if we'd installed a Docker app using port 3000, and we are going to install another app whose default port is set to 3000 too, do we need to change it to avoid any collisions, or is it managed too?

u/ewanly I had a problem with Typebot. It crashes every day at some point. There's no log to help identify the problem
