Packer で IDCFクラウドに仮想マシンテンプレートを作成する

概要

いつの間にか cloudstack builder が support されていたので IDCFクラウドに仮想マシンテンプレートを作成。

環境

• Packer v1.0.0

IDCFクラウド側の事前準備

• エンドポイント URL, API_KEY, SECRET_KEY 取得
• ソースのパブリック IP アドレス ID を取得※
• Keypair 登録

※packer にて temporary で public IP address を取得可能ですが、IDCFクラウドにおいては以下のエラーが出るため、デフォルトでついてくるソース IP アドレスを利用

==> cloudstack: Failed to associate public IP address: CloudStack API error 431 (CSExceptionErrorCode: 4350): Unable to figure out zone to assign ip to

• zone: newton
• OS: CentOS 7.3 64-bit
• マシンタイプ: light.S1

構築内容
provisioner で Ansible インストールまでして、その他諸々は ansible-local でプロビジョニングする。
