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.
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
