Once you've built up an understanding of how Kubernetes cluster configuration is managed, it's a good idea to explore the additional tools that offer enhanced mechanisms or abstractions to configure the state of your clusters.
ksonnet is one such tool, which allows you to build a structure around your various configurations in order to keep many environments configured. ksonnet uses another powerful tool called Jsonnet in order to maintain the state of the cluster. ksonnet is a different approach to cluster management that's different from the Helm approach we discussed in earlier chapters, in that it doesn't define packages by dependency, but instead takes a composable prototype approach, where you build JSON templates that are rendered by the ksonnet CLI to apply state on the cluster. You start with parts that create prototypes...
