In this example, we show how a JWT filter can be used with the Envoy proxy.

See https://www.envoyproxy.io/docs/envoy/latest/configuration/http_filters/jwt_authn_filter for official docs.

Usage

1. docker-compose build
2. docker-compose up
3. Post to any endpoint except /health, e.g localhost:8000/service using the following good token as found in https://github.com/envoyproxy/envoy/blob/c7b290085582a089afea078ca17b8ab7709ec51b/test/extensions/filters/http/jwt_authn/test_common.h
