Create a Kubernetes cluster.
Create a kubernetes cluster using command line flags. This command creates cloud based resources such as networks and virtual machines. Once the infrastructure is in place Kubernetes is installed on the virtual machines.
These operations are done in parallel and rely on eventual consistency.
kops create cluster
# Create a cluster in AWS

# Create a cluster in AWS that has HA masters. This cluster
# will be setup with an internal networking in a private VPC.
# A bastion instance will be setup to provide instance access.
