Clusterator

Docker image that can spin up or tear down clusters in GKE.

Creating a cluster

The create script will iterate the list of names supplied by the names file. It will first check to see if that name already exists in the project. If so we skip it and move on to the next name. Otherwise, we try and create a cluster with that name. Creation of the cluster is a blocking operation. After that takes place we will set the version of the cluster to the appropriate value (this operation is not blocking).

Deleting clusters

The delete script will iterate all names and if that name appears in the project it will attempt to remove it (this operation is not blocking).
