Kafka Topic View
Kafka Topic View is a simple UI for monitoring Kafka topics and their state. It lists all Kafka brokers, and the partitions assigned to them. The partitions are listed as squares with colors from green (the partitions is in good shape) to red (the partition is under-replicated or offline). When you hover over the partition square, a tooltip shows the details of the partition.
TODO
- Configure refresh interval in the UI
- Add SASL support
- Better logging
- CI build

In Kubernetes with Strimzi
Edit the deployment-strimzi.yaml file to match your Strimzi cluster setup (secret names, cluster name, bootstrap servers etc.) and deploy it to Kubernetes:
kubectl apply -f deployment-strimzi.yaml
Use kubectl proxy or kubectl port-forward to access the UI.
Build
Build the Golang backend first:
go build
If needed, build also the container with the backend and UI:
docker build -t <org>/<image>:<tag> ./
