Quick start

The easiest way to start working with Kouncil is by using Docker:
docker run -d -p 80:8080 -e bootstrapServers="kafka1:9092" -e"inmemory" consdata/kouncil:latest
There is only two required environment variables: bootstrapServers which should point to one of the brokers in your Kafka cluster and which specified authentication mode. For example, if your cluster consists of three brokers - kafka1:9092, kafka2:9092, kafka3:9092 - you only have to specify one of them (-e bootstrapServers="kafka1:9092"), and you are good to go, Kouncil will automatically do the rest!
Additionally, Kouncil supports multiple clusters. Hosts specified in bootstrapServers may point to brokers in several clusters, and Kouncil will recognize that properly. Brokers should be separated using comma, i.e.: docker run -d -p 80:8080 -e bootstrapServers="kafka1:9092,kafka1.another.cluster:8001" -e"inmemory" consdata/kouncil:latest
After the docker run command head to http://localhost.
