Simple Containers Management

A simple setup I use to manage docker containers in web application context. It includes nginx-proxy-manager and portainer.

Principles

nginx-proxy-manager will be the only service with open ports (80 and 443) on local host
All the containers must use the nxpm network and don't need to publish ports on local host

# Example of a docker-compose.yml file with a service joining the existing nxpm network 
version: "3.8"

services:
  myservice:
    image: someimage
    networks:
      - nxpm

networks:
  nxpm:
    external: true

Run the stack

Change database passwords in .env and production.json
You might want to change images version in .env
Bring the containers up :

$ docker-compose up -d

Connect to nginx-proxy-manager administration interface on port 81. By default, this interface is only exposed locally on the machine running the docker containers. To remotely accessing the admin interface use ssh tunneling (e.g. ssh -L 8181:127.0.0.1:81 user@remote_host) and access the interface on your local machine (e.g. http://localhost:8181)
Log in to the admin interface with default user/password ([email protected]/changeme) and update the admin user and password
You might want to create in nginx-proxy-manager a proxy host for its admin interface (Forward Hostname : nxpm / Forward Port : 81) and generate a Let's Encrypt certificate for it.
Create a proxy host for portainer (Forward Hostname : portainer / Forward Port : 9000) and generate a Let's Encrypt certificate for it.
You're good to go ! 🚀
