Use the VMware Validated Design Certificate Generation Utility (CertGenVVD) to generate certificate signing request (CSR) files that you can send to a third-party certificate authority and receive CA-signed certificates for the management components in Region B.

Prerequisites

A Window host that is that has access to your data center.

Procedure

  1. Log in to a Windows host that has access to your data center.
  2. Download the CertGenVVD-version.zip file of the Certificate Generation Utility from VMware Knowledge Base article 2146215 on the Windows host where you connect to the data center and extract the ZIP file to the C: drive.
  3. In the C:\CertGenVVD-version folder, open the default.txt file in a text editor.
  4. Verify that the following properties are configured.
    ORG=Rainpole Inc.
    OU=Rainpole.local
    LOC=LAX
    ST=CA
    CC=US
    CN=VMware_VVD
    keysize=2048
  5. Verify that the C:\CertGenVVD-version\ConfigFiles folder contains only following files.

  6. Verify that each configuration file includes FQDN and host names in the dedicated sections.

    For example, the configurations files for the Platform Service Controller instances must contain the following properties:

    lax01psc01.txt

    [CERT] 
    NAME=default
    ORG=default 
    OU=default
    LOC=LAX
    ST=default
    CC=default
    CN=lax01psc01.lax01.rainpole.local
    keysize=default
    [SAN]
    lax01psc01.lax01.rainpole.local
    lax01m01psc01.lax01.rainpole.local
    lax01w01psc01.lax01.rainpole.local
  7. Open a Windows PowerShell prompt and navigate to the folder of the CertGenVVD utility.
    cd C:\CertGenVVD-version
  8. Grant permissions to run third-party PowerShell scripts.
    Set-ExecutionPolicy Unrestricted
  9. Validate if you can run the utility using the configuration on the host and verify if VMware is included in the printed CA template policy.
    .\CertgenVVD-version.ps1 -validate
  10. Generate certificate request files for the management components in the SDDC.
    .\CertGenVVD-version.ps1 -CSR
  11. Locate the CSR files in the C:\CertGenVVD-version\CSRCerts folder and send it to the third-party CA to get the signed certificates.
  12. After you obtain all the signed certificate files and the root CA certificate, move the signed certificate files back to each directory where the CSR files reside.
  13. In a command prompt, navigate to the folder that contains the CA root certificate and rename it to Root64.cer.
  14. If the certificates are signed by multiple intermediate CAs, concatenate the certificates in one certificate chain file by running the following command.
    copy IntermediateCAroot01.cer+IntermediateCAroot02.cer+RootCA.cer > Root64.cer
  15. Move the Root64.certo the C:\CertGenVVD-version\CSRCerts\Root64 folder.
  16. Run CertGenVVD tool with the -CSR and -extra command options to generate all certificates that are required for the SDDC management components.
    .\CertGenVVD-version.ps1 –CSR -extra

What to do next

Replace the product certificates with the certificates that the CertGenVVD utility has generated. See Replace Certificates of the Virtual Infrastructure Components in Region B and Replace Certificates of the Operations Management Components in Region B.
