Manage Subclouds Using the CLI

You can use the to list subclouds, reconfigure subclouds if deployment fails, delete subclouds, and monitor or change the managed status of subclouds.

  • To list subclouds, use the subcloud list command.

    For example:

    ~(keystone_admin)]$ dcmanager subcloud list
+----+-----------+--------------+--------------------+-------------+
| id | name      | management   | availability       | sync        |
+----+-----------+--------------+--------------------+-------------+
|  1 | subcloud1 | managed      | online             | in-sync     |
|  2 | subcloud2 | managed      | online             | in-sync     |
|  3 | subcloud3 | managed      | online             | out-of-sync |
|  4 | subcloud4 | managed      | offline            | unknown     |
+----+-----------+--------------+--------------------+-------------+

  • To show information for a subcloud, use the subcloud show command.

    ~(keystone_admin)]$ dcmanager subcloud show <subcloud-name>

    For example:

    ~(keystone_admin)]$ dcmanager subcloud show subcloud2
+-----------------------------+----------------------------+
| Field                       | Value                      |
+-----------------------------+----------------------------+
| id                          | 2                          |
| name                        | subcloud2                  |
| description                 | subcloud2 description      |
| location                    | subcloud 2 location        |
| software_version            | nn.nn                      |

  • To show information about the oam-floating-ip field for a specific subcloud, use the subcloud show <subcloud-name> --detail command.

    For example,

    ~(keystone_admin)]$ dcmanager subcloud show subcloud2 --detail
+-----------------------------+----------------------------+
| Field                       | Value                      |
+-----------------------------+----------------------------+

| description                 | subcloud2 description      |
| location                    | subcloud 2 location        |

| management_gateway_ip       | 192.168.101.1              |

  • To edit the settings for a subcloud, use the subcloud update command.

    ~(keystone_admin)]$ dcmanager subcloud update \
[–- description] <description> \
[– location] <location> \
<subcloud-name>

  • To toggle a subcloud between Unmanaged and Managed, pass these parameters to the subcloud command.

    For example:

    ~(keystone_admin)]$ dcmanager subcloud unmanage <subcloud-name>
    ~(keystone_admin)]$ dcmanager subcloud manage <subcloud-name>

  • To reconfigure a subcloud, if deployment fails, use the subcloud reconfig command.

    Note

    You can enter the sysadmin password to avoid being prompted for the password.

    ~(keystone_admin)]$ dcmanager subcloud reconfig <subcloud-id/name> --deploy-config \
<filepath> --sysadmin-password <<password>>

    where --deploy-config must reference the deployment configuration file.

    partner

    Note

    The subcloud can be managed only if the deploy status is 'complete'.

    Run the following command to manage the subcloud:

    ~(keystone_admin)]$ dcmanager subcloud manage <subcloud-id/name>

  • To delete a subcloud, use the subcloud delete command.

    ~(keystone_admin)]$ dcmanager subcloud delete <subcloud-name>

    Caution

    You must reinstall a deleted subcloud before re-adding it.

  • To show detailed information about subcloud install/bootstrap/deploy failures, use the subcloud errors <subcloud-name> command.

    For example:

    [sysadmin@controller-0 ~(keystone_admin)]$ dcmanager subcloud errors 1
FAILED bootstrapping playbook of (subcloud1).
 detail: fatal: [subcloud1]: FAILED! => changed=true
