How to manage SQLite databases on a Linux Ubuntu server with Lite Queen and Docker

Ready to get Lite Queen up and running on your Ubuntu server using Docker? You're in the right place! Docker is the esiest way to run and manage Lite Queen. This guide will walk you through the steps to do just that, keeping things simple and straightforward.

Install dependencies: the only thing you need to get started is Docker.
Run Lite Queen: let's get Lite Queen running:
```
docker run -d --restart unless-stopped -p 8080:8000 -v /var/www:/srv -v $(pwd)/litequeen-data:/home/litequeen/data --name lite-queen-container kivsegrob/lite-queen
```
Breakdown of some important flags:
- The -v /var/www:/srv flag, mounts the location of all our SQLite databases in the container(/srv). This way we can access a database like so: /srv/path-to_database. Change /srv/www with the location of the database files on your system.
- -v $(pwd)/litequeen-data:/home/litequeen/data mounts a folder on our system to enable Lite Queen to persist its data. Change (pwd)/litequeen-data with the folder location you want Lite Queen to keep its data.
- The -d flag makes Lite Queen run in the background.
- --restart unless-stopped allows Lite Queen to restart automatically in case of error or when your server restarts.
- -p 8080:8000 maps the port running on your system(8080) to the container running Lite Queen--runs on port 8000 internally.

Exposing and securing Lite Queen: Lite Queen should be running on http://localhost:8080 now. To make it accessible to the internet via a domain, with some added security, let's set up Caddy(you're free to use any another webserver like Nginx, etc):

litequeen.example.com {

    @blocked {
        not remote_ip xx.xx.xx.xx # Whitelisted IP Address, replace with your own
        not remote_ip yy.yy.yy.yy # We can add multiple IP adresses too
    }
    respond @blocked "Not allowed" 403

    basicauth * { 
        # Password hashed with Caddy's hash-password command
        testing $2a$14$0EaqE/lqNro14adPf/c2COOdqfXukT5hXIS9.ZwRj0FMBQcWTYxR.
    }

    reverse_proxy :8080
}

Now, Lite Queen is not only up and running, but also secured with basic authentication and accessible to only users with a certain IP address at https://litequeen.example.com. And there you have it! Happy hosting!
