Implementation Using Golang Kong
To illustrate how to implement an API gateway using Golang Kong, let’s look at a simple deployment and configuration.
Quick Start with Golang Kong
Golang Kong can be installed with a straightforward command. Here are the basic steps to deploy Kong:
curl -sSO https://download.konghq.com/gateway-3.0.x/install.sh; bash install.sh
Once installed, you can configure your API and add plugins as necessary. Below is a sample configuration to create a simple API service with logging enabled.
Example Configuration
_format_version: "1.1"
services:
- name: example_service
url: https://httpbin.org
routes:
- name: example_route
paths:
- /example
plugins:
- name: request-logger
This configuration sets up a service pointing to https://httpbin.org and routes requests coming to /example while enabling a request logger plugin to capture requests.
Conclusion
In conclusion, both Golang Kong and Urfav offer unique advantages that can cater to various organizational needs.
