Bootstrap Data

You can use one or more mechanisms to pass information to a new VNF when it is originally launched. The VNF can use this information for system configuration purposes or to determine running options for the services it provides.

The mechanisms used to convey information from the Cloud OS to the VNF are the metadata server and config drive.

• User data is made available to the VNF through either the metadata service or the configuration drive.

• The cloud-init package reads information from either the metadata server or the configuration drive.

Detailed information about the OpenStack metadata server, config drive, and cloud-init is available online.
