Deploy Docker, Docker-Compose, Portainer and NPM (Nginx Proxy Manager)

Saturday, July 30, 2022 Docker

In this tutorial, you will learn to install and configure Docker, Docker-compose, the Portainer container management solution on a Linux server and use it to create and manage Docker containers to run different apps. You will also learn to put these containers behind Nginx using the Nginx proxy manager.The Nginx proxy manager (NPM) is a reverse proxy management system running on Docker. NPM is based on an Nginx server and provides users with a clean, efficient, and beautiful web interface for easier management.

Install Docker & Docker-Compose

Ubuntu System:

apt install docker.io -y && apt install docker-compose

CentOS System:

Install Docker on CentOS 8:

curl -sSL https://get.docker.com/ | sh 
systemctl start docker 
systemctl enable docker

Install Docker Compose on CentOS 8:

Important: Check the latest version of docker-compose from https://docs.docker.com/compose/release-notes/ then modify following command with latest version number. (I got 1.29.2 for this installation)

curl -L "https://get.daocloud.io/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

Notes:

Install Docker, Docker-Compose, Portainer & Nginx on CentOS 8 & Ubuntu 20.04

Install Portainer

Commands to install Portainer:

[[email protected] ~]# docker volume create portainer_data
portainer_data
[[email protected] ~]# docker run -d -p 9000:9000 --name portainer --restart always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce:latest

Access Portainer:

Make sure your VPS's 9000 port has been opened.

Verify Portainer from Internet by visiting http://<VPS's Public IP>:9000

Install NPM

Install Docker and Docker-Compose

Create a docker-compose.yml file similar to this:

version: '3'
services:
  app:
    image: 'jc21/nginx-proxy-manager:latest'
    restart: unless-stopped
    ports:
      - '80:80'
      - '81:81'
      - '443:443'
    volumes:
      - ./data:/data
      - ./letsencrypt:/etc/letsencrypt

Bring up your stack by running

docker-compose up -d

Log in to the Admin UI

When your docker container is running, connect to it on port 81 for the admin interface. Sometimes this can take a little bit because of the entropy of keys.

http://127.0.0.1:81

Default Admin User:

Email:    [email protected]
Password: changeme

Immediately after logging in with this default user you will be asked to modify your details and change your password

Log in and change password.

Access NPM

1 Open the URL https://<yourserverIP>:81 in your browser, and you will get the following screen. Enter the following default credentials to sign in.

Email address: [email protected] Password: changeme

2 Next, you will be immediately asked to set a name and an email address. Click the Save button, and you will be asked to create a new password. Click the Save button again to get started.

3 Visit the Hosts >> Proxy Hosts and click the Add Proxy Host button.

4 Enter the domain name as portainer.example.com. Choose the scheme as https. Enter the name of the container as the Forward Hostname and 9443 as the Forward port. Check the options Block Common Exploits and Websockets Support options.
