5.2. 外部認証プロバイダーを使用する ROSA with HCP クラスターの作成

手順

• OIDC_ID、SUBNET_IDS、および OPERATOR_ROLES_PREFIX 変数を使用して環境を準備した場合は、これらの変数をクラスターの作成時にも引き続き使用できます。たとえば、以下のコマンドを実行します。

  $ rosa create cluster --hosted-cp --subnet-ids=$SUBNET_IDS \
     --oidc-config-id=$OIDC_ID --cluster-name=<cluster_name> \
     --operator-roles-prefix=$OPERATOR_ROLES_PREFIX \
     --external-auth-providers-enabled

• 環境変数を設定していない場合は、以下のコマンドを実行します。

  $ rosa create cluster --cluster-name=<cluster_name> --sts --mode=auto \
      --hosted-cp --operator-roles-prefix <operator-role-prefix> \
      --oidc-config-id <ID-of-OIDC-configuration> \
      --external-auth-providers-enabled \
      --subnet-ids=<public-subnet-id>,<private-subnet-id>

検証

• 次のコマンドを実行して、クラスターの詳細で外部認証が有効になっていることを確認します。

  $ rosa describe cluster --cluster=<cluster_name>
