This is so we have the same behaviour as on GCE. This also lets us change the bootstrap script or the config, which is nice. Instance data is immutable on AWS once it is booted. Fix #21150
Cluster Configuration
The scripts and data in this directory automate creation and configuration of a Kubernetes cluster, including networking, DNS, nodes, and master components.
See the getting-started guides for examples of how to use the scripts.
cloudprovider/config-default.sh contains a set of tweakable definitions/parameters for the cluster.
The heavy lifting of configuring the VMs is done by SaltStack.
