bash <(curl -s https://raw.githubusercontent.com/cylonchau/kubernetes-generator/main/generator.sh)

Postrequisites

• certificate files
  • output-generate/certs/etcd, you can copy pki to /etc/etcd/
  • output-generate/certs/kubernetes, you can copy to /etc/kubernetes/
• rsyslog config file, copy to /etc/rsyslog.d/, don't forget restart service rsyslog
  • output-generate/rsyslog/kubernetes.conf
• systemd files, copy to /usr/lib/systemd/system/
  • output-generate/system
• binary files, kubernetes binary file
  • output-generate/bin
• auth files, don't forget update kubernetes cluster ip to available ip
  • output-generate/kubernetes/master,kubelet/auth

cp -a output-generate/cert/etcd/pki/ /etc/etcd/
