The process to update the Keystone admin user password includes steps that stop and start the nova services.
Note: The update triggers the OpenStack Lifecycle Manager pipeline and updates each Helm chart. The update might interrupt OpenStack services for a short time.
Note: If vROPs has been deployed in the environment, the keystone/horizon password configured in vROPs also needs to be updated accordingly. On the vROPS UI, open the 'Manage Credential' dialog box for VIO adapter. Update the "OpenStack Password" for the admin user.
Because nova services use the Keystone admin password to check the service status, we need to stop these services before changing the Keystone admin password.
Prerequisites
Important: You can encrypt the base64 password with the following command. If you do not include -n, then the new encrypted password contains a new line, which will result in errors.
echo -n 'input' | openssl base64
