How to install spinnaker on local kubernetes cluster
I would look at using Helm for this. Helm is a package manager for Kubernetes that makes installing applications in your cluster very easy.
Helm uses a packaging format called charts. A chart is basically a collection of files that describe a related set of Kubernetes resources.
There is a Spinnaker Helm Chart available here that will install all Spinnaker services into your cluster with one command.
helm install --name my-spinnaker stable/spinnaker
