# Here is a script to deploy cert to hashicorp vault using curl
|
|
# (https://www.vaultproject.io/)
|
|
#
|
|
# it requires 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
|
|
# VAULT_KV_V2 - set to anything if you are using v2 of the kv engine
|
|
#
|
|
# additionally, you need to ensure that VAULT_TOKEN is avialable
|
|
# to access the vault server
|
|
|
|
#returns 0 means success, otherwise error.
