We rename it to EPHEMERAL_BLOCK_DEVICE_MAPPINGS, and we also change the value so that it starts with a `,`, instead of always inserting a comma before it. In this way the value can be empty. Also, if the user sets the (currently experimental) KUBE_AWS_STORAGE environment variable to be "ebs", then we will not mount any instance storage which will cause the machines to use EBS storage instead.
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.
