2.2. ノードの登録

ノード定義のテンプレート (instackenv.json) は JSON ファイル形式で、ノード登録用のハードウェアおよび電源管理の情報が含まれています。たとえば、以下のようになります。

{
    "nodes":[
        {
            "mac":[
                "b1:b1:b1:b1:b1:b1"

}

テンプレートを作成したら、stack ユーザーのホームディレクトリーにファイルを保存します (/home/stack/instackenv.json)。stack ユーザーを初期化し、続いて instackenv.json を director にインポートします。

$ source ~/stackrc
$ openstack overcloud node import ~/instackenv.json

このコマンドでテンプレートをインポートして、テンプレートから director に各ノードを登録します。

カーネルと ramdisk イメージを各ノードに割り当てます。

$ openstack overcloud node configure <node>

director でのノードの登録、設定が完了しました。
