• zone and machine-type are required in order to create a VM instance
• Metadata can be passed to the instance by using --metadata={{ attribute name }}={{ attribute value }} which then can be retrieved by curl -H "Metadata-Flavor: Google" http://http://metadata.google.internal/computeMetadata/v1/instance/attributes/{{ attribute name }} while inside the instance.
