libcloudを使用しないでGoogleComputeEngineのDynamicInventoryScriptを使ってみる

環境

• OSX 10.10.2 (Yosemite)
• Python 2.7.9 (OSXにデフォルトインストールされてるPython)

必要なライブラリのインストール

※ 自分の環境ではこれを入れないと動かなかった

$ brew install gmp
$ sudo pip install pycrypto

インベントリスクリプトとiniを取得

$ wget https://github.com/ansible/ansible/blob/devel/plugins/inventory/gce.ini -P ~/.ansible
$ wget https://raw.githubusercontent.com/ansible/ansible/devel/plugins/inventory/gce.py -P ~/.ansible
$ chmod 755 ~/.ansible/gce.py

gce.iniに設定を記述(libcloudを使わない)

[gce]
# GCE Service Account configuration information can be stored in the
# libcloud 'secrets.py' file.  Ideally, the 'secrets.py' file will already
# exist in your PYTHONPATH and be picked up automatically with an import
# statement in the inventory script.  However, you can specify an absolute
# path to the secrets.py file with 'libcloud_secrets' parameter.
libcloud_secrets = 

# If you are not going to use a 'secrets.py' file, you can set the necessary
# authorization parameters here.
gce_service_account_email_address = [e-mail]
gce_service_account_pem_file_path = ~/.ansible/example.pem
gce_project_id = example-test-12345

動作確認
