Practical Application Demonstration

To illustrate the capabilities of Kong Gateway, let's walk through a simple API management scenario:

1. Install Kong Gateway:
   # Using Docker
   docker run -d --name kong \
     -e "KONG_DATABASE=off" \
     -e "KONG_PROXY_LISTEN=0.0.0.0:8000" \
     kong:latest
2. Configure a service:
   curl -i -X POST http://localhost:8001/services \
     --data "name=example-service" \
     --data "url=http://example.com"
3. Create a route:
   curl -i -X POST http://localhost:8001/services/example-service/routes \
     --data "paths[]=/example"
4. Test the API:
   curl -i http://localhost:8000/example

This example demonstrates how to set up a basic service and route using Kong Gateway, highlighting its user-friendly interface and powerful capabilities.
