Generates a self-signed CA to provision identities for etcd


Generates the self-signed etcd certificate authority and related key and saves them into etcd/ca.crt and etcd/ca.key files.

If both files already exist, kubeadm skips the generation step and existing files will be used.

Alpha Disclaimer: this command is currently alpha.

      --config string     Path to kubeadm config file (WARNING: Usage of a configuration file is experimental)
  -h, --help              help for etcd-ca
