Deploying Spinnaker on Docker Desktop

After preparation for leading an internal workshop on Spinnaker, I decided to share the tutorial for getting Spinnaker up and running on OSX using Docker Desktop:

* Halyard installation: locally on OSX
* Cloud Provider: Kubernetes (Manifest-based)
* Environment: Distributed installation on Kubernetes
* Persistent storage: S3 via Minio deployed on Kubernetes
* Deploy Spinnaker: 1.11.9 (Cobra Kai)

Install Halyard
