Is Vault deployment a requirement?

[SeungwookL]

Hi, I currently have Vault and Rundeck deployed on different instances, but trying to use Vault as my secret backend using Vault-Storage plugin. Would this be possible or do I need Vault installed on the same instance that Rundeck is installed on?

Here is the configuration I used for the plugin, which did not work:

rundeck.storage.provider.1.type=vault-storage
rundeck.storage.provider.1.path=keys
rundeck.storage.provider.1.removePathPrefix=true
rundeck.storage.provider.1.config.prefix=rundeck
rundeck.storage.provider.1.config.secretBackend=secret
rundeck.storage.provider.1.config.address=$VAULT_ADDRESS
rundeck.storage.provider.1.config.authBackend=token
rundeck.storage.provider.1.config.token= $VAULT_TOKEN
rundeck.storage.provider.1.config.storageBehaviour=vault
rundeck.storage.provider.1.config.engineVersion=2

I am using the following versions:
Rundeck - 3.2.3
Vault - 1.2.3
