We shouldn't upgrade etcd without first warning the user that some etcd version transitions can't be undone. We don't know what version the user currently has, so we require either an explicit version and image, or an interactive acknowledgement of this caveat. This is modeled after the STORAGE_MEDIA_TYPE prompt just above.
Cluster Configuration
Deprecation Notice: This directory has entered maintenance mode and will not be accepting new providers. Please submit new automation deployments to kube-deploy. Deployments in this directory will continue to be maintained and supported at their current level of support.
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.
