Kafka ACL Viewer

An application to display your Kafka cluster ACLs as a graph of topics and consumers/producers. It allows you to visualise how events flow within your cluster in a simple way. See the picture below for an example of how it can look.

Note: some operation and resource types are not displayed and resources (read topics) may not always be "real" topics, the ACL may be a wildcard resource such as * for all topics. Don't use this data as the absolute truth of what accesses are in your cluster.

I wrote a blog about this project here.

Authentication with Kafka

This application is built to authenticate against Kafka using TLS. It requires two ACL entries on the broker to function properly. The first one, to read ACLs from the cluster itself --cluster --operation describe and to describe all topics in the cluster, --topic='*' --operation describe.
