5.3. 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。これらのコマンドにより、ホストに直接アクセスせずに、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。
前提条件
- Bare Metal Provisioning サービスが含まれるオーバークラウドのデプロイメントが正常に完了していること。詳細は、Deploying an overcloud with the Bare Metal Provisioning service を参照してください。
手順
以下のコマンドを実行して、各ホストの IP アドレスを表示します。
(undercloud) [stack@host01 ~]$ openstack stack output show overcloud HostsEntry --max-width 80 +--------------+---------------------------------------------------------------+ | Field | Value | +--------------+---------------------------------------------------------------+ | description | The content that should be appended to your /etc/hosts if you | | | want to get | | | hostname-based access to the deployed nodes (useful for | | | testing without | | | setting up a DNS). | | | | | output_key | HostsEntry | | output_value | 172.17.0.10 overcloud-controller-0.localdomain overcloud- | | | controller-0 | | | 10.8.145.18 overcloud-controller-0.external.localdomain | | | overcloud-controller-0.external | | | 172.17.0.10 overcloud-controller-0.internalapi.localdomain | | | overcloud-controller-0.internalapi | | | 172.18.0.15 overcloud-controller-0.storage.localdomain | | | overcloud-controller-0.storage | | | 172.21.2.12 overcloud-controller-0.storagemgmt.localdomain | | | overcloud-controller-0.storagemgmt | | | 172.16.0.15 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 | | | | | | 172.17.0.21 overcloud-compute-0.localdomain overcloud- | | | compute-0 | | | 10.8.146.12 overcloud-compute-0.external.localdomain | | | overcloud-compute-0.external | | | 172.17.0.21 overcloud-compute-0.internalapi.localdomain | | | overcloud-compute-0.internalapi | | | 172.18.0.20 overcloud-compute-0.storage.localdomain | | | overcloud-compute-0.storage | | | 10.8.146.12 overcloud-compute-0.storagemgmt.localdomain | | | overcloud-compute-0.storagemgmt | | | 172.16.0.16 overcloud-compute-0.tenant.localdomain overcloud- | | | compute-0.tenant | | | 10.8.146.12 overcloud-compute-0.management.localdomain | | | overcloud-compute-0.management | | | 10.8.146.12 overcloud-compute-0.ctlplane.localdomain | | | overcloud-compute-0.ctlplane | | | | | | | | | | | | | | | 10.8.145.16 overcloud.localdomain | | | 10.8.146.7 overcloud.ctlplane.localdomain | | | 172.17.0.19 overcloud.internalapi.localdomain | | | 172.18.0.19 overcloud.storage.localdomain | | | 172.21.2.16 overcloud.storagemgmt.localdomain | +--------------+---------------------------------------------------------------+
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。
