# 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. |
