#/bin/bash

# Creates a node-pool following the best security practices at the time.
# Turns off unsafe addons and uses a service account with the minimum
# set of needed permissions to run Kubernetes. See
# https://cloudplatform.googleblog.com/2017/11/precious-cargo-securing-containers-with-Kubernetes-Engine-18.html

# This script presumes the service account has already been created, which is
# done in ./create-cluster.sh, which needs to have been run before this
# script.
