# Cleaning up nodes is simple:
### Declare colors to use during the running of this script:
declare -r GREEN="\033[0;32m"
declare -r RED="\033[0;31m"
declare -r YELLOW="\033[0;33m"

function echo_green {
  echo -e "${GREEN}$1"; tput sgr0
}
function echo_red {
  echo -e "${RED}$1"; tput sgr0
}
function echo_yellow {
  echo -e "${YELLOW}$1"; tput sgr0
}

  ### These can optionally be enabled, but a menu is soon to come to clean up the following binaries:
  # sudo rm -rf /usr/local/bin/bootkube
  # sudo rm -rf /usr/local/bin/kubectl
  # sudo rm -rf /usr/local/bin/kubelet
  # sudo rm -rf /usr/local/bin/helm
  # sudo rm -rf /usr/local/bin/hostess
  # sudo rm -rf /opt/cni
  sudo rm -rf /etc/systemd/system/kubelet.service
  sudo systemctl daemon-reload
  ### These can optionally be enabled, but Docker will need to be reinstalled, and volumes will be perm removed:
  # sudo apt-get remove docker.io -y
  # sudo rm -rf /var/lib/docker
  # sudo rm -rf /var/lib/kubelet
  # sudo rm -rf /var/lib/dockershim
  sudo rm -rf /var/lib/openstack-helm/*
  sudo rm -rf /var/lib/nova
