You can import a certificate with a private key to replace the default self-signed certificate, after activation.

You can import self-signed or CA-signed certificates for platform or services using this procedure with the following exceptions:
  • A CSR generated on NSX Manager which is self-signed cannot be used as a service certificate, such as the Load Balancer service. If you want to import a CA certificate for the Load Balancer service, see Import a CA Certificate.
  • On a stand-by Global Manager, the UI import operation is deactivated. Use the following REST API command to complete the import of a platform certificate on the standby GM. The display name is optional, but if not used, ensure the last attribute does not contain a trailing comma. Be sure to replace any end of line character with \n. The entire certificate should be provided in a single line. In order to replace newline characters with \n, you can use this command on UNIX based systems to convert each .pem (certificate and key) file to a value that can be passed in a JSON string to the NSX-T Data Center API: awk 'NF {sub(/\r/, ""); printf "%s\\n",$0;}' certificate-name.pem. The new format places all the certificate information on a single line with embedded newline characters.

    For example:

    POST https://<nsx-mgr>/api/v1/trust-management/certificates?action=import

    Note: In some cases, issues have been reported with certificates that contain \r\n in the PEM format. According to the X509 certificate standard, it is acceptable and NSX Manager allows these certificates to be used and in many cases there are no error results.

Prerequisites

  • Verify that a certificate is available.
  • The server certificate must contain the Basic Constraints extension basicConstraints = cA:FALSE.
