APISIX API Gateway Setup and Configuration


Introduction


APISIX is an open-source API gateway that provides high performance, scalability, and extensibility for managing APIs. This guide will walk you through setting up and configuring APISIX to manage your API traffic efficiently.


Prerequisites

  • Basic knowledge of APIs and microservices
  • Docker installed on your system
  • Linux/MacOS/Windows system for deployment


Step 1: Set Up APISIX with Docker


  1. Clone the APISIX repository from GitHub using the command:
    2. git clone https://github.com/apache/apisix.git
  2. Navigate to the project directory:
    3. cd apisix
  3. Start the APISIX Docker container with the command:
    4. docker-compose up -d

Step 2: Access APISIX Dashboard


Once APISIX is up and running, you can access its dashboard by navigating to http://localhost:8080. The default login credentials are:

  • Username: admin
  • Password: admin


Step 3: Configure an API in APISIX


To configure an API, follow these steps:

  1. Log in to the APISIX Dashboard.
  2. Go to the Routes tab and click on Create.
  3. Fill in the details for your API route:
    • URI: The API endpoint (e.g., /my-api)
    • Upstream: Define the backend service URL (e.g., http://localhost:8081)


Step 4: Test the API Gateway


Once your API route is set up, test it by sending a request to the APISIX gateway. For example:

curl http://localhost:9080/my-api

This should proxy the request to the backend API you configured earlier.



Conclusion

In this tutorial, we learned how to set up and configure APISIX as an API gateway for managing and routing API traffic. With its high performance and flexibility, APISIX is a great choice for modern microservices architectures.
