In order for kops to store cluster configuration, a dedicated S3 bucket is required.

An example for the eu-west-1 region would look as follows:

$ aws s3api create-bucket --bucket s3.k8s.containerized.me 
--region eu-west-1 --create-bucket-configuration 
LocationConstraint=eu-west-1

This S3 bucket will become the source of truth for our Kubernetes cluster configuration. For simplicity, it is recommended to use the us-east-1 region; otherwise, an appropriate LocationConstraint needs be specified in order to create the bucket in the desired region.
