5.4. ホストから IP アドレスへのマッピングの確認
各 IP アドレスが割り当てられているホストおよびベアメタルノードを確認するには、以下のコマンドを使用します。
この機能により、ホストに直接アクセスする必要なく、ホストから IP へのマッピングをアンダークラウドで確認することが可能です。

特定のホストに絞り込むには、以下のコマンドを実行します。
(undercloud) [stack@host01 ~]$ openstack stack output show overcloud HostsEntry -c output_value -f value | grep overcloud-controller-0 172.17.0.12 overcloud-controller-0.localdomain overcloud-controller-0 10.8.145.18 overcloud-controller-0.external.localdomain overcloud-controller-0.external 172.17.0.12 overcloud-controller-0.internalapi.localdomain overcloud-controller-0.internalapi 172.18.0.12 overcloud-controller-0.storage.localdomain overcloud-controller-0.storage 172.21.2.13 overcloud-controller-0.storagemgmt.localdomain overcloud-controller-0.storagemgmt 172.16.0.19 overcloud-controller-0.tenant.localdomain overcloud-controller-0.tenant 10.8.146.13 overcloud-controller-0.management.localdomain overcloud-controller-0.management 10.8.146.13 overcloud-controller-0.ctlplane.localdomain overcloud-controller-0.ctlplane
ホストをベアメタルノードにマッピングするには、以下のコマンドを実行します。
