Install and configure Nginx Proxy Manager

If like me you host several services at home or in production,  you are not going to set up a certificate on each server or docker, the easiest way to manage certificates is to centralize certificate management in a single node or docker. Traefik is much favored but I prefer Nginx proxy manager because it is easy to use and light and above all to add a service by UI in a simpler way. Traefik is useful for its configuration files, the logic of its configuration and the integration of Docker / Kubernetes. But above all Traefik becomes the ideal solution when I load/unload containers, it is the only one that allows me to simply manage the ports dynamically.

Installation with Docker Compose

Here are the steps to configure Nginx Proxy Manager with Certbot and MariaDB using Docker Compose from ubuntu server :

sudo apt update
sudo apt install -y docker.io
sudo apt install -y docker-compose

Create a new directory for your Nginx Proxy Manager :

sudo mkdir /opt/nginx-proxy-manager
cd /opt/nginx-proxy-manager

Create a docker-compose.yml file :

sudo nano docker-compose.yml

Paste the following configuration to your docker-compose file :

version: '3'

services:
  app:
    image: 'jlesage/nginx-proxy-manager'
    container_name: nginx-proxy-manager
    ports:
      - '80:80'
      - '8081:81'
      - '443:443'
    volumes:
      - '/etc/localtime:/etc/localtime:ro'
      - '/opt/nginx-proxy-manager/data:/config'
    restart: always
    environment:
      - 'VIRTUAL_HOST=mydomain.com'
      - 'FORCE_SSL=true'
      - 'TZ=America/New_York'
    depends_on:
      - mariadb

  mariadb:
    image: mariadb
    container_name: mariadb
    volumes:
      - mariadb:/var/lib/mysql
    restart: always
    environments:
      MYSQL_ROOT_PASSWORD: my-secret-pw
      MYSQL_DATABASE: nginx_proxy_manager
      MYSQL_USER: nginxpm
      MYSQL_PASSWORD: nginxpm-password

  certbot:
    image: certbot/certbot
    container_name: certbot
    volumes:
      - '/opt/nginx-proxy-manager/letsencrypt:/etc/letsencrypt'
      - '/opt/nginx-proxy-manager/data:/data/letsencrypt'
    command: certonly --webroot --webroot-path=/data/letsencrypt --email youremail@example.com --agree-tos --no-eff-email --domain example.com
    depends_on:
      - app

networks:
  default:
    external:
      name: nginx-proxy-manager_default

volumes:
  mariadb:

Note: Replace "mydomain.com" with your domain name, "youremail@example.com" with your email address, and follow the prompts to generate the SSL certificate and edit mysql configuration and create a network and volume using the following command :

sudo docker network create nginx-proxy-manager_default
sudo docker volume create mariadb

Start the Docker containers using the following command :

sudo docker-compose up -d

Access the Nginx Proxy Manager web interface by visiting http://mydomain.com:81. Login with the default credentials:
Username: admin@example.com
Password: changeme

Follow the Nginx Proxy Manager documentation to configure your reverse proxy rules, set up SSL certificates, and more.
That's it! You have now configured Nginx Proxy Manager with Certbot and MariaDB using Docker Compose.
