4.8.2. Customizing an instance by using metadata

You can use instance metadata to specify the properties of an instance in the instance launch command.


  1. Launch an instance with the --property <key=value> option. For example, to mark the instance as a webserver, set the following property:

    $ openstack server create \
    --image rhel8 \
    --flavor default \
    --property role=webservers \
    --wait web-server-instance
  2. Optional: Add an additional property to the instance after it is created, for example:

    $ openstack server set \
    --property region=emea \
    --wait web-server-instance
