Boot instance dari image dan menghubungkan volume non-bootable¶
Membuat volume non-bootable dan menghubungkan dimana volume ke sebuah instance dimana Anda boot dari sebuah image.
Untuk membuat volume non-bootable, jangan menciptakannya dari sebuah image. Volume harus sepenuhnya kosong tanpa tabel partisi dan tidak ada sistem file.

Boot an instance from an image and attach the empty volume to the instance, use the
--block-device-mappingparameter.Sebagai contoh:
$ openstack server create --flavor FLAVOR --image IMAGE \ --block-device-mapping DEV-NAME=ID:TYPE:SIZE:DELETE_ON_TERMINATE \ NAME
Parameter adalah:
--flavorThe flavor ID or name.--imageThe image ID or name.--block-device-mappingDEV-NAME=ID:TYPE:SIZE:DELETE_ON_TERMINATE- DEV-NAME
The device name to attch the volume when the instance is booted.
- ID
ID dari objek sumber.
- TYPE

Membuat volume dari image dan boot instance¶
Anda dapat membuat volume dari sebuah image, volume, atau snapshot yang ada. Prosedur ini menunjukkan Anda bagaimana untuk membuat volume dari sebuah image, dan menggunakan volume untuk boot sebuah instance.
Daftar image yang tersedia.
$ openstack image list +-----------------+---------------------------------+--------+ | ID | Name | Status | +-----------------+---------------------------------+--------+ | dfcd8407-486... | Fedora-x86_64-20-20131211.1-sda | active | | c76cf108-176... | cirros-0.3.5-x86_64-uec | active | | 02d6b27f-40b... | cirros-0.3.5-x86_64-uec-kernel | active | | 47b90a42-8f4... | cirros-0.3.5-x86_64-uec-ramdisk | active | +-----------------+---------------------------------+--------+
Perhatikan ID dari image yang ingin Anda gunakan untuk membuat volume.
Jika Anda ingin membuat volume ke backend penyimpanan tertentu, Anda perlu menggunakan image yang memiliki properti cinder_img_volume_type. Dalam hal ini, volume baru akan dibuat sebagai tipe volume *storage_backend1 *.

Menghubungkan swap atau fana disk (ephemeral disk) pada sebuah instance¶
To attach swap or ephemeral disk to an instance, you need create new flavor first. This procedure shows you how to boot an instance with a 512 MB swap disk and 2 GB ephemeral disk.
Create a new flavor.
$ openstack flavor create --vcpus 1 --ram 64 --disk 1 \ --swap 512 --ephemeral 2 my_flavor
Catatan
Flavor mendefinisikan swap maksimum dan ukuran disk ephemeral (tidal kekal). Anda tidak dapat melebihi nilai-nilai maksimum.
Create a server with 512 MB swap disk and 2 GB ephemeral disk.
$ openstack server create --image IMAGE_ID --flavor \ my_flavor NAME
