# http://pki-tutorial.readthedocs.io/en/latest/expert/index.html
# This script is made to run in non-interactive mode, with
# no password on the keyboard what so ever.
# It will create this:
#
# ----------- ---------- ----------------
# | ROOT CA | => | OCI CA | => | Server certs |
# ----------- ---------- ----------------
#
#
# To change names and so on, simply edit config files in
# the /etc/openstack-cluster-installer/pki folder.
#
# In production, you'd typically replace ROOT CA and OCI CA
# by real PKI infrastructure keys (ie: you'd only genreate keys
# for the Component CA).
