Chapter 12. Managing Ceph Object Gateway using the dashboard

As a storage administrator, the Ceph Object Gateway functions of the dashboard allow you to manage and monitor the Ceph Object Gateway.

You can also create the Ceph Object Gateway services with Secure Sockets Layer (SSL) using the dashboard.

For example, monitoring functions allow you to view details about a gateway daemon such as its zone name, or performance graphs of GET and PUT rates. Management functions allow you to view, create, and edit both users and buckets.

Ceph Object Gateway functions are divided between user functions and bucket functions.

12.1. Manually adding Ceph object gateway login credentials to the dashboard

The Red Hat Ceph Storage Dashboard can manage the Ceph Object Gateway, also known as the RADOS Gateway, or RGW. When Ceph Object Gateway is deployed with cephadm, the Ceph Object Gateway credentials used by the dashboard is automatically configured. You can also manually force the Ceph object gateway credentials to the Ceph dashboard using the command-line interface.

Prerequisites

  • A running Red Hat Ceph Storage cluster.
  • Dashboard is installed.
  • Ceph Object Gateway is installed.

Procedure

  1. Log into the Cephadm shell:

    Example

    [root@host01 ~]# cephadm shell

  2. Set up the credentials manually:

    Example

    [ceph: root@host01 /]# ceph dashboard set-rgw-credentials

    This creates a Ceph Object Gateway user with UID dashboard for each realm in the system.

  3. Optional: If you have configured a custom admin resource in your Ceph Object Gateway admin API, you have to also set the the admin resource:

    Syntax

    ceph dashboard set-rgw-api-admin-resource RGW_API_ADMIN_RESOURCE

    Example

    [ceph: root@host01 /]# ceph dashboard set-rgw-api-admin-resource admin
Option RGW_API_ADMIN_RESOURCE updated

  4. Optional: If you are using HTTPS with a self-signed certificate, disable certificate verification in the dashboard to avoid refused connections.

    Refused connections can happen when the certificate is signed by an unknown Certificate Authority, or if the host name used does not match the host name in the certificate.

    Syntax

    ceph dashboard set-rgw-api-ssl-verify false

    Example

    [ceph: root@host01 /]# ceph dashboard set-rgw-api-ssl-verify False
Option RGW_API_SSL_VERIFY updated

  5. Optional: If the Object Gateway takes too long to process requests and the dashboard runs into timeouts, you can set the timeout value:

    Syntax

    ceph dashboard set-rest-requests-timeout _TIME_IN_SECONDS_

    The default value of 45 seconds.

    Example

    [ceph: root@host01 /]# ceph dashboard set-rest-requests-timeout 240

12.2. Creating the Ceph Object Gateway services with SSL using the dashboard

After installing a Red Hat Ceph Storage cluster, you can create the Ceph Object Gateway service with SSL using two methods:

  • Using the command-line interface.
  • Using the dashboard.

Prerequisites

  • A running Red Hat Ceph Storage cluster.
  • Dashboard is installed.
  • SSL key from Certificate Authority (CA).
Note

Obtain the SSL certificate from a CA that matches the hostname of the gateway host. Red Hat recommends obtaining a certificate from a CA that has subject alternate name fields and a wildcard for use with S3-style subdomains.

Procedure

  1. From the dashboard navigation, go to Administration→Services.
  2. Click Create.

  3. Fill in the Create Service form.

    1. Select rgw from the Type service list.
    2. Enter the ID that is used in service_id.
    3. Select SSL.

    4. Click Choose File and upload the SSL certificate .pem format.

  10. From the secondary site, go to Object→Multi-site.

  11. Import the token from the primary zone, by clicking Import.

    1. In the Import Multi-site Token dialog, in the Zone section, paste the token that was copied earlier, and provide a secondary zone name.
    2. In the Service section, select the placement and the port where the new Ceph Object Gateway service is going to be created.

    3. Click Import.

      A warning is displayed to restart the Ceph Object Gateway service.

  12. Restart the Ceph Object Gateway service.

    1. From the dashboard navigation of the secondary site, go to Administration→Services.
    2. Select the Ceph Object Gateway service row and expand the row.
    3. From the Daemons tab, select the hostname.

    4. Click Restart from the action drop-down.

      Wait until the users are synced to the secondary site.

  13. Verify that the sync is complete using the following commands:

    Syntax

    radosgw-admin sync status
radosgw-admin user list

    Example

    [ceph: root@host01 /]# radosgw-admin sync status
[ceph: root@host01 /]# radosgw-admin user list

  14. In Object→Overview you get an error that "The Object Gateway Service is not configured". This bug is a known issue. See BZ#2231072.

    1. As a workaround, set the Ceph Object Gateway credentials on the command-line interface.

      Syntax

      ceph dashboard set-rgw-credentials
RGW credentials configured

    2. Go to Object→Overview to verify that you are able to access the Ceph Object Gateway on the dashboard.

  15. On the primary site, Object→Overview, in the Multi-Site Sync Status section, an error is displayed because on the secondary zone you can see that the endpoints and the hostname are not the IP address. This bug is a known issue while configuring multi-site. See BZ#2242994.

    1. As a workaround, from the secondary site dashboard, go to Object→Multi-site.
    2. Select the secondary zone and click the Edit icon.
    3. Edit the endpoints to reflect the IP address.
    4. Click Edit Zone.

  16. On the primary site and secondary site dashboards, from Object→Overview, in the Multi-Site Sync Status section, the status displays.

    Multi-site sync status

Verification

  • Create a user on the primary site. You see that the user syncs to the secondary site.
