ホスト・セットアップの確認

システム要件、ネットワーク要件、およびアウトバウンド接続要件を満たすホストを作成した後、以下のsat-host-checkスクリプトを実行して、ホストのセットアップを検証できます。

現在、 sat-host-check スクリプトにバグがあり、GLIBC の要件のために RHEL 上で失敗します。

  1. ホストにログインします。

    ssh root@<IP_address>
    1. RHEL ホストの場合、root として SSH を使用します。
        ssh root@<IP_address>
    ```
1. RHCOS ホストの場合は、公開 SSH 鍵をイグニッション・スクリプトにコピーし、コアとしてログインします。
    1. ホスト接続スクリプトをダウンロードし、公開 SSH 鍵を追加します。

        ```json {: codeblock}
        {
          "ignition": {
            "version": "3.1.0"
          },
          "passwd": {
            "users": [
              {
                "name": "core",
                "sshAuthorizedKeys": [ "PUBLIC-SSH-KEY" ]
              }
            ]
          },
        ...
        }
        ```
    1. ホストに`core`としてログインします。
        ```sh {: pre}
        ssh core@<IP_address>
        ```

  2. スクリプトをダウンロードして実行可能にします。

    curl https://<region>.containers.cloud.ibm.com/satellite-health/sat-host-check -o sat-host-check && chmod +x sat-host-check

    us-southのコマンド例。

    curl https://us-south.containers.cloud.ibm.com/satellite-health/sat-host-check -o sat-host-check && chmod +x sat-host-check

  3. このスクリプトを実行して、ロケーションを作成したリージョンを指定します。

    sudo ./sat-host-check --region $REGION

    us-southのコマンド例。

    sudo ./sat-host-check --region us-south

    {: pre}

    us-southでホストを検査するための出力例。

  4. テスト失敗の要約を確認します。 障害に応じて、要件を確認し、ホストを更新します。

  5. ホスト検査が成功した場合は、ご使用のロケーションへのホストの接続を続行できます。
