This is a updated guide to the previous Nginx Proxy Manager guide. It has a docker stack that has Nginx Proxy Manager and MariaDB. The docker-compose file is a modified example from jc21

Changes

A seprated network for the database backend so no other container has access to the nginx database.
frontend network for the container to be exposed to internet for proper proxy.
container_name is added, nginix-proxy-manger labelled as nginx-app and mariadb-aria is labelled as nginx-db, you can choose to rename for your deploy.

Deployment

A) You can clone repo
B) Download the docker-compose.yml
C) Copy the following into your own docker-compose.yml

version: '3'

networks:
  frontend:
    external: true
  backend:

services:
  npm-app:
    image: jc21/nginx-proxy-manager:latest
    container_name: nginx-app
    depends_on: 
      - npm-db
    restart: always
    ports:
      - "80:80"
      - "81:81"
      - "443:443"
    environment:
      - DB_MYSQL_HOST=npm-db
      - DB_MYSQL_PORT=3306
      - DB_MYSQL_USER=npm
      - DB_MYSQL_PASSWORD=MYSQLPASSWORD
      - DB_MYSQL_NAME=npm
    volumes:
      - ./data:/data
      - ./ssl:/etc/letsencrypt
    networks:
      - frontend
      - backend

  npm-db:
    image: jc21/mariadb-aria:latest
    restart: always
    container_name: nginx-db
    environment:
      - MYSQL_ROOT_PASSWORD=ROOTMYSQLPASSWORD
      - MYSQL_DATABASE=npm
      - MYSQL_USER=npm
      - MYSQL_PASSWORD=MYSQLPASSWORD
    volumes:
      - ./db:/var/lib/mysql
    networks:
      - backend

Then you have to make the external network frontend with the following command in terminal:

docker network create -d bridge frontend

Run docker compose up -d in the directory of the docker compose with terminal
Connect to your instance by connecting to the port 81 for admin controls. 127.0.0.1:81
the default login is:

Email:      admin@example.com
Password:   changeme

You will be asked to change the login credentials right after logging in for the 1st time.

Notes

Change the DB_MYSQL_PASSWORD= to a secure password
Change the MYSQL_ROOT_PASSWORD= to a secure password
Create the external network frontend before deployment otherwise it will not find the network and docker will error out.
