In this "how to" tutorial you are going to set up your own nginx instance with a mariaDB. Nginx [engine x] is an HTTP and reverse proxy server, a mail proxy server, and a generic TCP/UDP proxy server, and as an open source project is free to use.
First we are going to uninstall any old docker engine and install the latest (can be skipped), then we'll create/edit the docker-compose file, and check all the containers and the setup.
sudo apt-get purge docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin docker-ce-rootless-extras
curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh ./get-docker.sh --dry-run
sudo sh ./get-docker.sh
docker --version
mkdir nginx-with-postgres
cd nginx-with-postgres
vim docker-compose.yml
Paste the content inside this file.

version: "3.8"
services:
app:
hostname: 'nginx'
image: 'jc21/nginx-proxy-manager:latest'
container_name: 'nginx-app'
restart: 'unless-stopped'
ports:
## These ports are in format <host-port>:<container-port>
- '80:80' # Public HTTP Port
- '443:443' # Public HTTPS Port
- '81:81' # Admin Web Port
## Add any other Stream port you want to expose
## - '21:21' # FTP

DB_MYSQL_PORT: 3306
DB_MYSQL_USER: "nginx-user"
DB_MYSQL_PASSWORD: "changeMe.aHighlyComplexPasswordToKeepYouSecure"
DB_MYSQL_NAME: "npm"
## Uncomment this if IPv6 is not enabled on your host
## DISABLE_IPV6: 'true'
networks:
- 'nginx-network'
volumes:
- 'nginx-app-data-vol:/data'
- 'nginx-app-letsencrypt-vol:/etc/letsencrypt'

db:
image: 'jc21/mariadb-aria:latest'
container_name: 'nginx-db'
restart: 'unless-stopped'
environment:
MYSQL_DATABASE: 'npm'
MYSQL_USER: 'nginx-user'
MYSQL_PASSWORD: 'changeMe.aHighlyComplexPasswordToKeepYouSecure'
MYSQL_ROOT_PASSWORD: 'changeMe.aHighlyComplexPasswordToKeepYouSecure'
networks:
- 'nginx-network'
volumes:
- 'nginx-db-data-vol:/var/lib/mysql'
volumes:
nginx-app-data-vol:
name: 'nginx-app-data-vol'
nginx-app-letsencrypt-vol:

networks:
nginx-network:
name: 'nginx-network'
Edit the parts with 'changeMe.' and of course any other parts you want to modify, such as the ports exposed on the host machine.
Make sure you have changed all the 'changeMe.' parts. Now you are good to go.
With docker-compose, it's fairly easy to set everything up.
Type:
docker compose up -d
Deployment should take a maximum of 2 minutes to be up and running as the app waits for the db and a successful health check. Type:
docker ps -a
You should wait till the nginx-db container is up and healthy and the nginx-app is running.
Now you can check your port 80 (or another port if you have changed the left side) with your browser at localhost:80, or serverIP:80 if you run it on a server in a different network or your provided URL inside the docker-compose file.
If you cannot reach the URL after a few minutes (3 to 4), you should check your ufw/ufw-docker to expose the ports through the firewall or check your proxy manager, if you use one.
Congratulations, you have created your own nginx server with its own db in just a few minutes.
You can now access the server on the 81 port to open the admin panel and start configuring the proxy.
As you have seen, setting up nginx with its own db instance is quite simple and straightforward.
