  • The name of the network or networks to attach the instance to

  • The keypair name to allow access to an instance

  • The name of any security groups to associate with the instance

How to do it…

The instance we will boot will have the following attributes:

  • Instance name: cookbook.test

  • Flavor type: openstack.cookbook

  • Image name: Ubuntu 16.04 amd64 (UUID)

  • Network: public (UUID)
