Cluster state storage

Since we're building resources in the cloud using configuration management, we're going to need to store the representation of our cluster in a dedicated S3 bucket. This source of truth will allow us to maintain a single location for the configuration and state of our Kubernetes cluster. Please prepend your bucket name with a unique value.

Be sure to create your bucket in the us-east-1 region for now, as kops is currently opinionated as to where the bucket belongs:

aws s3api create-bucket \
 --bucket gsw-k8s-3-state-store \
 --region us-east-1

Let's go ahead and set up versioning as well, so you can roll your cluster back to previous states in case anything goes wrong. Behold the power of Infrastructure as Code!

aws s3api put-bucket-versioning --bucket gsw-k8s-3-state-store --versioning-configuration Status=Enabled
