description: Launch a basic instance with CirrOS image using the
``m1.tiny`` flavor, ``mykey`` key, and one network. parameters:
NetID:
type: string
description: Network ID to use for the instance. resources:
server:
type: OS::Nova::Server
properties:
image: cirros_test
flavor: m1.tiny
key_name: demo
networks:
- network: { get_param: NetID } outputs:
instance_name:
description: Name of the instance.
value: { get_attr: [ server, name ] }
instance_ip:
description: IP address of the instance.
value: { get_attr: [ server, first_address ] }
[root@armstrong ~]# source keystone_demo
注意，yam文件里的image，flavor，key_name可以利用openstack CLI获取
