Install the Rate Limiting plugin and enable it on the service.
Prerequisites
Kong Konnect
This is a Konnect tutorial. If you don’t have a Konnect account, you can get started quickly with our onboarding wizard.
The following Konnect items are required to complete this tutorial:
- Personal access token (PAT): Create a new personal access token by opening the Konnect PAT page and selecting Generate Token.
- Control plane: You can use an existing control plane or create a new one to use for this tutorial.
- Control plane ID: You can see your control plane ID by selecting a control plane from the Gateway Manager in Konnect.
Kong Gateway running
This tutorial requires Kong Gateway. If you don’t have it set up yet, you can use the quickstart script to get an instance of Kong Gateway running almost instantly:
curl -Ls https://get.konghq.com/quickstart | bash -s
Once Kong Gateway is ready, you will see the following message:
Kong Gateway Ready
decK
decK is a CLI tool for managing Kong Gateway declaratively with state files. To complete this tutorial you will first need to:
- Install decK
-
Create a
deck_files
directory and akong.yaml
file in the directory:mkdir deck_files && touch deck_files/kong.yaml
Pre-configured entities
For this tutorial, you’ll need Kong Gateway entities, like services and routes, pre-configured. These entities are essential for Kong Gateway to function but installing them isn’t the focus of this guide. Follow these steps to pre-configure them:
-
Create a
prereqs.yaml
file within yourdeck_files
directory, and add the following content to it:_format_version: '3.0' services: - name: example-service url: http://httpbin.org/anything routes: - name: example-route paths: - "/anything" service: name: example-service
-
Sync your changes.
deck gateway sync deck_files
Make sure to substitute your Konnect Personal Access Token for
konnect_token
and the control plane name forKONNECT_CP_NAME
in the command:deck gateway sync deck_files \ --konnect-token $KONNECT_TOKEN \ --konnect-control-plane-name $KONNECT_CP_NAME
To learn more about entities, you can read our entities documentation.
1. Enable rate limiting
Enable the Rate Limiting plugin for the service. In this example, the limit is 5 requests per second and 1000 requests per hour.
_format_version: '3.0'
plugins:
- name: rate-limiting
service: example-service
config:
second: 5
hour: 1000
2. Validate
After configuring the Rate Limiting plugin, you can verify that it was configured correctly and is working, by sending more requests than allowed in the configured time limit.
for _ in {1..6}
do
curl http://localhost:8000/example-route/anything/
done
After the 5th request, you should receive the following 429
error:
{ "message": "API rate limit exceeded" }
Cleanup
Clean up Konnect environment
If you created a new control plane and want to conserve your free trial credits or avoid unnecessary charges, delete the new control plane used in this tutorial.
