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

A broad costume category can help organise choices for events, group shoots and themed projects. The comparison can include colour, silhouette and the level of preparation required. For event or photo planning, Genshin Impact cosplay costumes（原神コスプレ衣装） keeps the selection connected to the intended series. It also helps separate series-level browsing from a specific item decision. A useful comparison considers character identity, preparation time and the planned setting. No single design should be treated as representative of every character in the work.

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.
