ratelimit
Go/gRPC service designed to enable generic rate limit scenarios from different types of applications. (by envoyproxy)
To use global rate limiting you need an external rate limiter service that keeps track of the domains that have to be rate limited. Luckily envoy provides a redis based ratelimit service. In the following sections you will learn how to configure the redis based ratelimit service and how to rate limit specific routes.
-
For the deployment of the ratelimit service you can use the ratelimitservice.yaml as a starting point. If you already have a redis instance in your kubernetes cluster, then feel free to use it for the rate limiter service as well and remove redis related parts. Adjust the ConfigMap ratelimit-config with your rate limiting rules and specify the REDIS_URL in the ratelimit Deployment. Now you can deploy the ratelimit service to your kubernetes cluster.
