#!/usr/bin/env sh
# Here is a script to deploy cert to hashicorp consul using curl
# (https://www.consul.io/)
#
# it requires following environment variables:
#
# CONSUL_PREFIX - this contains the prefix path in consul
# CONSUL_HTTP_ADDR - consul requires this to find your consul server
#
# additionally, you need to ensure that CONSUL_HTTP_TOKEN is available
# to access the consul server
#returns 0 means success, otherwise error.
