# 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
|
|
# VAULT_SAVE_TOKEN - set to anything if you want to save the token
|
|
# VAULT_RENEW_TOKEN - set to anything if you want to renew the token to default TTL before deploying
|
|
#
|
|
# 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.
