Kubernetes sidecars are one of the most important and commonly employed patterns in modern application infrastructures. However, developing and debugging such structures can be quite challenging. Gefyra helps to make Kubernetes-native development with sidecars possible. This session demonstrates: * how to run a Kubernetes workload containing Keycloak, the popular OAuth2-Proxy in a sidecar and a Python-based application * how the application container will be intercepted with Gefyra in order to introspect the JSON Web Token * how to debug the source code and provide a solution. Attendees will leave this session ready to leverage sidecars for authorization (i.e. OAuth2) use-cases and to use Gefyra for debugging and developing Kubernetes-based applications in local Docker containers.
