-If the OpenStack deployment is defined to use HTTPS endpoints, a certificate
-will be needed in the container in order to launch any command.

-The OS variable will point to that file. For example::
+If you need to connect to a server that is TLS-enabled (the auth URL begins with ‘https’)
+and it uses a certificate from a private CA or a self-signed certificate you will
+need to specify the path to an appropriate CA certificate to use to validate the

+Certificate verification can be turned off using OS_INSECURE=true.
