# Here is a script to deploy cert to hashicorp vault
# (https://www.vaultproject.io/)
#
# it requires the vault binary to be available in PATH, and the following
# environment variables:
#
# VAULT_PREFIX - this contains the prefix path in vault
# VAULT_ADDR - vault requires this to find your vault server
#
# additionally, you need to ensure that VAULT_TOKEN is avialable or
# `vault auth` has applied the appropriate authorization for the vault binary
# to access the vault server

#returns 0 means success, otherwise error.
