Cant deploy Freepbx/Nginx Stack because Docker is already using

[Pedronettcom]

Ask a Question!

Im using docker and docker compose to run Portainer and on it im running a few services to make a webchat and calls, to make the calling work i need to use freepbx but when i try to deploy it out of the Portainer, he takes the machine 443 Port whole to himself so i went to set up a containarized Nginx reverse proxy to prevent that but i cant because it says i cant bind the 443 port to it, docker is already using.

I want to know how to change my Nginx/Freepbx Stack options so that they dont conflict with Docker

You can change the port exposed on your host for your containers by modifying it in the docker-compose.yml file. For example:

services:
  nginx:
    image: nginx:latest
    container_name: nginx_web
    ports:
      - "8080:80"  # Maps port 8080 on the host to port 80 on the container
    volumes:
      - ./html:/usr/share/nginx/html  
      - ./nginx.conf:/etc/nginx/nginx.conf 
    restart: unless-stopped

In the ports section, where it says 8080, you can change this to any available port that won’t conflict with others on your host. For example, if you are running services on port 443, you can change the left-hand port of the colon to 8443:

ports:
  - "8443:80"

This will expose the container’s port 80 to port 8443 on your host.
