Kong Gateway is a lightweight, fast, and flexible cloud-native API gateway.
Kong Gateway sits in front of your service applications, dynamically controlling, analyzing, and
routing requests and responses. Kong Gateway implements your API traffic policies
by using a flexible, low-code, plug-in based approach.
This tutorial will help you get started with Kong Gateway by setting up a local installation
and walking through some common API management tasks.
This page will walk you through running Kong Gateway and verifying it with the
Admin API. Once complete, the following tasks
can be performed to complete the tutorial:
Docker is used to run Kong Gateway and supporting database locally
curl is used to send requests to Kong Gateway.
curl is pre-installed on most systems
jq is used to process JSON responses on the command line. While useful, this tool is
not necessary to complete the tasks of this tutorial. If you wish to proceed without
jq, modify the commands to
For the purposes of this tutorial, a
quickstart script is provided to quickly run Kong Gateway and its supporting database.
This script uses Docker to run Kong Gateway and a PostgreSQL database as the backing database.
Run Kong Gateway with the
curl -Ls https://get.konghq.com/quickstart | bash
Note: The quickstart script runs Kong Gateway Enterprise in Free mode. You may run Kong with a license by passing the license to the script via an environment variable. For instructions on this and other advanced usage, see the code repository documentation.
This script runs Docker containers for Kong Gateway and the supporting PostgreSQL database.
The script also creates a Docker network for those containers to communicate over. Finally, the database is
initialized with the appropriate migration steps,
and once the Kong Gateway is ready, you will see the following message:
Verify that Kong Gateway is running:
Kong Gateway serves an Admin API on the default port
8001. The Admin API can be used for
both querying and controlling the state of Kong Gateway. The following command
will query the Admin API, fetching the headers only:
curl --head localhost:8001
If Kong Gateway is running properly, it will respond with a
200 HTTP code, similar to the following:
HTTP/1.1 200 OK
Date: Mon, 22 Aug 2022 19:25:49 GMT
Content-Type: application/json; charset=utf-8
Evaluate the Kong Gateway configuration:
The root route of the Admin API provides important information about the running
Kong Gateway including networking, security, and plugin information. The full
configuration is provided in the
.configuration key of the returned JSON document.
curl -s localhost:8001 | jq '.configuration'
You should receive a large JSON response with Kong Gateway configuration information.
Access Kong Manager
While the rest of this guide demonstrates configuring Kong Gateway using the Admin API, you can also use Kong Manager to manage your Services, Routes, Plugins, and more. To access Kong Manager, go to the following URL: http://localhost:8002
Note: If you install Kong Gateway (OSS), you will use Kong Manager Open Source. All other Kong Gateway installations use Kong Manager Enterprise.
Every step in this tutorial requires a running Kong Gateway, so leave
everything running and proceed to the next steps in this tutorial.
