OpenStack環境
OpenStackはUbuntu12.04LTS上にGrizzly版DevStackをインストールしたものを利用した。
DevStackのインストールはSingleMachine構成での構築を行った。
参考： http://devstack.org/guides/single-machine.html
EC2互換APIでOpenStackを操作するための設定
参考となるページは下記。

この手順の中でTENANT_IDはEC2用のテナントをあらかじめ作っていく必要があるので注意。
EC2互換APIでインスタンスの起動、停止をしてみる。
イメージの一覧
$ euca-describe-images IMAGE aki-00000001 None (cirros-0.3.1-x86_64-uec-kernel) 1de8ba1352274a98800e8c5dfee5cfa4 available public kernel instance-store IMAGE ari-00000002 None (cirros-0.3.1-x86_64-uec-ramdisk) 1de8ba1352274a98800e8c5dfee5cfa4 available public ramdisk instance-store IMAGE ami-00000003 None (cirros-0.3.1-x86_64-uec) 1de8ba1352274a98800e8c5dfee5cfa4 available public machine aki-00000001 ari-00000002 instance-store
イメージIDを指定してインスタンスを起動
$ euca-run-instances ami-00000003 RESERVATION r-0jhbhphs 1de8ba1352274a98800e8c5dfee5cfa4 default INSTANCE i-00000001 ami-00000003 server-311f5bb8-48dc-43a8-a16f-137ca31b95e4 server-311f5bb8-48dc-43a8-a16f-137ca31b95e4 pending None (1de8ba1352274a98800e8c5dfee5cfa4, None) 0 m1.small 2013-06-17T03:14:07.000Z nova aki-00000001 ari-00000002 monitoring-disabled instance-store
インスタンス起動時のオプションは下記の通り。
euca-run-instances [-A, --access-key <access_key> ][-A, --secret-key <secret_key> ][--config <config_path> ][--debug][--debugger][-h, --help][--region <region_name> ][-U, --url ][--version][--euca-auth][-n, --instance- count ][-g, --group <group_name> ][-k, --key ][-d, --user-data <user_data> ][--user-data-force <user_data_force> ][-f, --user-data-file <user_data_file> ][--addressing ][-t, --instance-type <instance_type> ][--kernel ][--ramdisk ][-b, --block-device-mapping <block_device_mapping> ][--monitor][-s, --subnet ][-z, --availability-zone ] image_id
ちなみに、OpenStack 標準コマンドの nova boot のオプションとの主な項目の対比は下記の通り。
| EC2 | OpenStack |
|---|---|
| image_id | –image |
| –instance-count | –num-instances |
| –group | –security-groups |
| –key | –key-name |
| –user-data | –user-data |
| –user-data-file | –file |
| –instance-type | –flavor |
| –block-device-mapping | block-device-mapping |
| –availability-zone | –availability-zone |

インスタンスの停止
$ euca-terminate-instances Terminates the specified instances.
一通りは使えそう。
