Strimzi Quickstart

Getting up and running with a Apache Kafka cluster on Kubernetes and OKD can be very simple, when using the Strimzi project! This quick start guide walks you through a quick and easy install for your development environment, using OKD.

Start OKD

This assumes that you have the latest version of the oc binary, which you can get here.

TO DO

SL = serialization library.
SC = SerializationContext
DC = DeserializationContext

`SerializationContext.getReference()`

Add method SerializationContext.getReference(Instance instance) to get the SerializableReference of an already registered instance:

	#!/usr/bin/sh
	#
	# An example hook script to check the commit log message.
	# Called by "git commit" with one argument, the name of the file
	# that has the commit message. The hook should exit with non-zero
	# status after issuing an appropriate message if it wants to stop the
	# commit. The hook is allowed to edit the commit message file.
	#
	# To enable this hook, rename this file to "commit-msg".
