Why?
See for yourself, but we think this project gives you better adaptability than [helm](https://github.com/kubernetes/helm) [chart](https://github.com/kubernetes/charts/tree/master/incubator/kafka)s. No single readable readme or template can properly introduce both Kafka and Kubernets.
No readable readme can properly introduce both [Kafka](http://kafka.apache.org/) and [Kubernets](https://kubernetes.io/),
but we think the combination of the two is a great backbone for microservices.
Back when we read [Newman](http://samnewman.io/books/building_microservices/) we were beginners with both.
Now we've read [Kleppmann](http://dataintensive.net/), [Confluent](https://www.confluent.io/blog/) and [SRE](https://landing.google.com/sre/book.html) and enjoy this "Streaming Platform" lock-in :smile:.

We also think the plain-yaml approach of this project is easier to understand and evolve than [helm](https://github.com/kubernetes/helm) [chart](https://github.com/kubernetes/charts/tree/master/incubator/kafka)s.

## What you get

Keep an eye on `kubectl --namespace kafka get pods -w`.

That's it. Just add business value :wink:.
For clients we tend to use [librdkafka](https://github.com/edenhill/librdkafka)-based drivers like [node-rdkafka](https://github.com/Blizzard/node-rdkafka).
To use [Kafka Connect](http://kafka.apache.org/documentation/#connect) and [Kafka Streams](http://kafka.apache.org/documentation/streams/) you may want to take a look at our [sample](https://github.com/solsson/dockerfiles/tree/master/connect-files) [Dockerfile](https://github.com/solsson/dockerfiles/tree/master/streams-logfilter)s.
