Atlas CLI バージョン 1.52.0 以降、atlas deployments コマンドは非推奨です。ローカル配置には atlas local コマンドを使用します。このチュートリアルを atlas local コマンドを使用するように更新しました。
このチュートリアルでは、atlas local コマンドを使用してMongoDB Searchインデックスの作成、クエリの実行、ローカル配置でMongoDB ベクトル検索 を操作する方法を説明します。
前提条件を完了する
始める前に、次の前提条件を完了してください。
重要
依存関係リスト内の各製品の互換性情報については、製品のインストール ドキュメントを参照してください。
例（MacOS）:
brew install mongodb-atlas-cli 他のオペレーティング システムの Atlas CLI をインストールする手順については、「 Atlas CLIのインストールまたは更新 」を参照してください。
mongoshバージョン2.0以降をインストールします。
例（MacOS）:
brew install mongosh 他のオペレーティング システムの
mongoshインストール手順については、「 mongosh のインストール 」を参照してください。（任意） Compassバージョン1.39.4以降をインストールします。
例（MacOS）:
brew install mongodb-compass 他のオペレーティング システムの Compass をインストールする手順については、「 Compass のダウンロードとインストール 」を参照してください。
MongoDB Database Tools をインストールします。
例（MacOS）:
brew tap mongodb/brew && brew install mongodb-database-tools 他のオペレーティング システムの MongoDB Database Tools をインストールする手順については、「 Database Tools のインストール 」を参照してください。
MacOS またはWindowsの場合は、 Docker Desktop v4.31+ をインストールします。
Linuxの場合は、Docker Engine v27.0+ をインストールします。
注意
Docker では、MongoDB イメージをプルしてキャッシュするためにネットワーク接続が必要です。
Podman v5.0+ はLinux RHEL バージョンでもサポートされています。
Atlas 配置の作成。
例:
atlas local setup 詳細については、「 Atlas 配置のローカル配置の作成 」を参照してください。
重要
MongoDB ベクトル検索で Atlas CLI を使用するには、 MongoDB 7.0.5 以降で Atlas 配置を作成する必要があります。以前のMongoDBバージョンでローカル Atlas 配置を作成した場合、自動的に最新のMongoDBバージョンは取得されません。以前のイメージと配置を削除する必要があります。その後、新しい Atlas 配置を作成する必要があります。
サンプル データをダウンロードしてロードします。
例:
サンプル データをダウンロードするには、次のコマンドを実行します。
curl https://atlas-education.s3.amazonaws.com/sampledata.archive -o sampledata.archive 次のコマンドをコピーしてターミナルに貼り付け、
{port-number}を配置用のポートに置き換えます。mongorestore --archive=sampledata.archive --port={port-number}
制限事項を確認する
次の制限が適用されます。
同時検索は実行できません。
ブール値句は1024を超えることはできません。
MongoDB Search インデックスの作成とクエリの実行
MongoDB Search を操作するには、atlas local コマンドを使用します。詳しくは、MongoDB Search を参照してください。
このコマンドは、次の方法で実行できます。
対話モード: コマンドはMongoDB Search 設定を要求します。
注意
インタラクティブ モードでは、デフォルト設定で基本的なMongoDB Searchインデックスを作成できます。
非対話型モード（フラグ） : 指定されたオプションを使用して コマンドを実行します。 コマンドでは、それ以上の値を指定するように求められません。
非対話型モード（構成ファイル） : 構成ファイルで指定された設定を持つ コマンドを実行します。 コマンドでは、それ以上の値を指定するように求められません。
次のいずれかのタブをクリックすると、ご希望モードのコマンドが表示されます。

Atlas 配置でMongoDB ベクトル検索 を使用する
ローカル配置でMongoDB ベクトル検索 を操作するには、atlas local コマンドを使用します。詳細については、 ベクトル検索用のベクトル埋め込みのインデックス作成方法 を参照してください。
重要
MongoDB ベクトル検索で Atlas CLI を使用するには、 MongoDB 7.0.5 以降で Atlas 配置を作成する必要があります。以前のMongoDBバージョンでローカル Atlas 配置を作成した場合、自動的に最新のMongoDBバージョンは取得されません。以前のイメージと配置を削除する必要があります。その後、新しい Atlas 配置を作成する必要があります。
