openstack flavor create
一、创建一个实例类型(flavor)
命令：
openstack flavor create \
--id 'id_flavor_m1_nano' \
--vcpus 4 \
--ram $(( 1024 * 16 )) \
--disk 200 m1.nano

备注：$(( ))是linux 里做数学计算的一种写法，也可以用 $[ ]。
执行结果：
root@OpenStack:~# openstack flavor create --id 'id_flavor_m1_nano' --vcpus 4 --ram $(( 1024 * 16 )) --disk 200 m1.nano /usr/lib/python3/dist-packages/secretstorage/dhcrypto.py:15: CryptographyDeprecationWarning: int_from_bytes is deprecated, use int.from_bytes instead from cryptography.utils import int_from_bytes /usr/lib/python3/dist-packages/secretstorage/util.py:19: CryptographyDeprecationWarning: int_from_bytes is deprecated, use int.from_bytes instead from cryptography.utils import int_from_bytes +----------------------------+-------------------+ | Field | Value | +----------------------------+-------------------+ | OS-FLV-DISABLED:disabled | False | | OS-FLV-EXT-DATA:ephemeral | 0 | | description | None | | disk | 200 | | id | id_flavor_m1_nano | | name | m1.nano | | os-flavor-access:is_public | True | | properties | | | ram | 16384 | | rxtx_factor | 1.0 | | swap | | | vcpus | 4 | +----------------------------+-------------------+

二、生成访问 key
命令：
openstack keypair create --public-key ~/.ssh/id_rsa.pub key

执行结果：
root@OpenStack:~# openstack keypair create --public-key ~/.ssh/id_rsa.pub key /usr/lib/python3/dist-packages/secretstorage/dhcrypto.py:15: CryptographyDeprecationWarning: int_from_bytes is deprecated, use int.from_bytes instead from cryptography.utils import int_from_bytes /usr/lib/python3/dist-packages/secretstorage/util.py:19: CryptographyDeprecationWarning: int_from_bytes is deprecated, use int.from_bytes instead from cryptography.utils import int_from_bytes +-------------+-------------------------------------------------+ | Field | Value | +-------------+-------------------------------------------------+ | created_at | None | | fingerprint | 9d:b1:80:3d:cc:2a:7d:ad:54:97:a2:4a:28:89:c2:e5 | | id | key | | is_deleted | None | | name | key | | type | ssh | | user_id | f0f29beca3b24ae59a5270d666c4f812 | +-------------+-------------------------------------------------+

备注：执行 openstack keypair list可验证 key 是否创建成功。
三、启动实例
1. 查看可用的实例类型
root@OpenStack:~# openstack flavor list
