接続クラスタはサポートしている Google Cloud サービスに依存しているため、クラスタのアウトバウンド ファイアウォール ルールを変更して、次のドメインへのアクセスを許可する必要があります。これは、GKE 接続クラスタをインストールして実行するためにクラスタに対して行う必要のある唯一の変更です。

Google やサードパーティの認証情報を、 Google Cloud リソースへの有効期間が短いアクセス トークンと交換できます。クラスタが Google Cloud リージョンを使用してフリートに登録された場合は、許可リストに REGION-gkemulticloud.googleapis.com を登録する必要があります（例: us-central1-gkemulticloud.googleapis.com）。

This includes setting up the correct user credentials in the `kubeconfig` file.\n- Ensure that there is network connectivity to your cluster.\n- Ensure the cluster Kubernetes version is at least 1.25. The Kubernetes major.minor version should match the selected platform version.\n- The selected platform version must be at least:\n\n 1.25.0-gke.8\n 1.26.0-gke.6\n 1.27.0-gke.3\n\n You can also list all supported versions using: \n\n gcloud container attached get-server-config \\\n --location=\u003cvar translate=\"no\"\u003eGOOGLE_CLOUD_REGION\u003c/var\u003e\n\n Release notes for each platform version can be found at the\n [supported versions](/kubernetes-engine/multi-cloud/docs/attached/generic/reference/supported-versions) page.\n\nNetworking requirements\n-----------------------\n\nBecause attached clusters rely on supporting Google Cloud services, you need to\nmodify your cluster's outbound firewall rules to allow it\naccess to the following domains. This is the only change you need to make to\nyour cluster to install and run GKE attached clusters.\n\n### Logging and monitoring\n\nTo use logging and monitoring features, your cluster also needs to\nbe able to access the following URLs: \n\n logging.googleapis.com\n monitoring.googleapis.com\n opsconfigmonitoring.googleapis.com\n kubernetesmetadata.googleapis.com\n\nGoogle Cloud requirements\n-------------------------\n\nBefore attaching your cluster to the Google Cloud management service, you must\ninstall the gcloud CLI, including the Google Cloud CLI command, and\ngrant access to your Google Cloud account to the Google Cloud management\nservice so it can manage your attached cluster resources.\n\n1. Check your gcloud CLI installation with the following command:\n\n gcloud version\n\n2. If the gcloud CLI isn't installed, or if its version is earlier than\n version 412.0.0, install version 412.0.0 or higher by following the\n [gcloud CLI installation instructions](/sdk/docs/install).\n\n3. Install the `kubectl`\n [additional component](/sdk/docs/components#additional_components).\n\n4. If you haven't already done so,\n [create your Google Cloud project](/resource-manager/docs/creating-managing-projects#creating_a_project).\n This will generate a Google Cloud project ID and a project number.\n\n5. Set your active Google Cloud project and authenticate your account with\n the following commands.\n\n export PROJECT_ID=\u003cyour project id\u003e\n gcloud auth login\n gcloud config set project $PROJECT_ID\n gcloud auth application-default login\n\n6. Enable the GKE attached clusters API and its required services with\n the following commands:\n\n gcloud services enable gkemulticloud.googleapis.com\n gcloud services enable gkeconnect.googleapis.com\n gcloud services enable connectgateway.googleapis.com\n gcloud services enable cloudresourcemanager.googleapis.com\n gcloud services enable anthos.googleapis.com\n gcloud services enable logging.googleapis.com\n gcloud services enable monitoring.googleapis.com\n gcloud services enable opsconfigmonitoring.googleapis.com\n gcloud services enable kubernetesmetadata.googleapis.com"]]
