Pre-Requisites: Docker: Install Using Convenience Script:

curl -fsSL https://get.docker.com -o get-docker.sh && sudo sh get-docker.sh

Docker-Compose:
Install Using:

sudo apt-get install docker-compose

Steps Create docker-compose.yaml file with content:

version: "3"
services:
  nginx:
    image: nginx:latest
    restart: always
    ports:
      - "80:80"
    networks:
      - nginxnetwork
    volumes:
      - ./nginx/nginx.conf:/etc/nginx/nginx.conf
      - ./nginx/sites-available:/etc/nginx/conf.d
networks:
  nginxnetwork:

Create directory nginx to hold configurations to be mounted into the container.
Create nginx/nginx.conf file with this content: Add all your custom configs if any.

user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    include /etc/nginx/conf.d/*;
}

Create all your nginx site configs in the dirctory nginx/sites-available
Create a docker-compose-nginx.service file in /etc/systemd/system/ with the content:

[Unit]
Description=Docker Compose NGINX Service
Requires=docker.service
After=docker.service network.target

[Service]
Type=oneshot
RemainAfterExit=yes
WorkingDirectory=/home/mvdev
ExecStart=/usr/local/bin/docker-compose up -d
ExecStop=/usr/local/bin/docker-compose down
TimeoutStartSec=0

[Install]
WantedBy=multi-user.target

Enable the service:

sudo systemctl enable docker-compose-nginx.service

Reload systemctl to read the service

sudo systemctl daemon-reload

Start the service:

sudo service docker-compose-nginx start

Verify its running using:

sudo service docker-compose-nginx status

Now you can create as many configs as you want without rebuilding or committing to nginx docker image. Also, on reboot, our service will handle everything for us. Good Luck. Questions/Contributions/Criticisms are more than welcome.
