#Here is a scipt to deploy the cert to your TrueNAS using the REST API.
# https://www.truenas.com/docs/hub/additional-topics/api/rest_api.html
#
# Written by Frank Plass github@f-plass.de
#
#
# Following environment variables must be set:
#
# export DEPLOY_TRUENAS_APIKEY="<API_KEY_GENERATED_IN_THE_WEB_UI"
#
# The following environmental variables may be set if you don't like their
# default values:
#
# DEPLOY_TRUENAS_HOSTNAME - defaults to localhost
# DEPLOY_TRUENAS_SCHEME - defaults to http, set alternatively to https
#
#returns 0 means success, otherwise error.
