  • --description <description>: can be added for additional descriptions.
  • sources such as image, volume, or snapshot, which should have been created before making an instance.

    • --volume <volume-name-or-id>: specify a volume image
    • --snapshot <snapshot-name-or-id>: specify a snapshot image
  • --flavor <flavor-name-or-id>: specify a flavor name, eg. c2.m16, or flavor id.
  • --nic <network-id> or --auto-network: either a priviate network or public network.
  • --security-group <security-group-name-or-id>: security group for this instance.
  • --key-name <keypair-name-or-id>: keypair for this instance.
openstack server create --description <description> --image/volume/snapshot <image/volume/snapshot-name-or-id> --flavor <flavor-name-or-id> --auto-network/--nic <network-id> --security-group <security-group-name-or-id> --key-name <keypair-name-or-id> <instance-name>

Delete an Instance

openstack server delete <instance-name-or-id>

Shelve an Instance

openstack server shelve <instance-name-or-id>

openstack server unshelve <instance-name-or-id>

Resize an Instance

For --flavor option, it could be flavor name, eg. c2.m16, or flavor id.

openstack server resize --flavor <flavor-name-or-id> <instance-name-or-id>

After resizing, confirm or revert by doing one of the following:

openstack server resize confirm <instance-name-or-id>
openstack server resize revert <instance-name-or-id>

Pause an Instance

Two useful options are --enable-delete-on-termination and --disable-delete-on-termination. --enable-delete-on-termination deletes the volume once instance is deleted. --disable-delete-on-termination keeps the volume in the project once instance is deleted.

openstack server add volume <instance-name-or-id> <volume-name-or-id>

Detach a Volume from an Instance

openstack server remove volume <instance-name-or-id> <volume-name-or-id>
