ASF GitHub Bot commented on NIFI-3331: -------------------------------------- GitHub user pvillard31 opened a pull request: https://github.com/apache/nifi/pull/1491 NIFI-3331 - TLS Toolkit - add the possibility to define SAN in issued… … certificates ================================================================= Issue behind this improvement is: if you have a load balancer in front of your NiFi cluster, you may have the following issue - when accessing the UI (secured cluster, HTTPS) you might face a certificate issue because the certificate issuer won't match the address of the load balancer. One option to solve this issue is to add, in addition to the node host name, the load balancer address as Subject Alternative Names in the certificate. This should help when deploying tools like Knox, HAProxy, etc, in front of NiFi with HTTPS access. This PR adds an option in the TLS Toolkit when using it in client mode. The option allows user to define a comma separated list of domains to add as SAN (in the example: the node and the load balancer). The domains will be added in the CSR sent to the CA and the CA will issue a signed certificate containing the same SAN. ================================================================= Thank you for submitting a contribution to Apache NiFi.
