2. Run the Docker Container:

   sudo docker run -d -p 8080:80 filedesign/stirlingpdf

3. Access Stirling PDF: Open your browser and navigate to http://your-vps-ip:8080.

Step 4: Test Your Installation

You can verify if Stirling PDF is running by accessing its API endpoints. You might use cURL or Postman to test, such as:

curl http://your-vps-ip:8080/ping

Ensure you receive a confirmation response to know that the service is running properly.

Customizing Your Setup

Environment Variables

Stirling PDF can use configurations via environment variables. Modify your Docker run command to include any necessary settings:

sudo docker run -d -p 8080:80 -e OPTION=VALUE filedesign/stirlingpdf

Securing Your Server
