Hi Team, I am exploring secret management options in Apache NiFi 2.8.0 and would like to understand whether NiFi supports retrieving passwords directly from HashiCorp Vault KV during startup.
My use case is to store the following properties in Vault KV rather than in nifi.properties: - nifi.security.keystorePasswd - nifi.security.keyPasswd - nifi.security.truststorePasswd The objective is to avoid storing these sensitive values in plain text on the NiFi host while still allowing NiFi to access them during the bootstrap/startup process. I am specifically interested in startup configuration properties that are required before the application is fully initialized. Has anyone successfully configured NiFi 2.8.0 to retrieve these passwords directly from HashiCorp Vault KV during startup? If so, are there any recommended approaches, examples, or best practices for this use case? Any guidance would be appreciated. Thank you.
