17.4. 配置 Ceph 对象存储以使用外部 Ceph 对象网关

流程

1. 将以下 parameter_defaults 添加到自定义环境文件，如 swift-external-params.yaml，并调整值以符合您的部署：

   parameter_defaults:
      ExternalSwiftPublicUrl: 'http://<Public RGW endpoint or loadbalancer>:8080/swift/v1/AUTH_%(project_id)s'
      ExternalSwiftInternalUrl: 'http://<Internal RGW endpoint>:8080/swift/v1/AUTH_%(project_id)s'
      ExternalSwiftAdminUrl: 'http://<Admin RGW endpoint>:8080/swift/v1/AUTH_%(project_id)s'
      ExternalSwiftUserTenant: 'service'
      SwiftPassword: 'choose_a_random_password'

   注意

   示例代码片段包含与您在环境中使用的值不同的参数值：

   • 远程 RGW 实例侦听 8080 的默认端口。端口可能根据配置外部 RGW 的不同而有所不同。
   • overcloud 中创建的 swift 用户使用 SwiftPassword 参数定义的密码。您必须将外部 RGW 实例配置为使用同一密码通过 rgw_keystone_admin_password 与 Identity 服务进行身份验证。

2. 将以下代码添加到 Ceph 配置文件，将 RGW 配置为使用 Identity 服务。替换变量值以适合您的环境：

       rgw_keystone_api_version = 3
       rgw_keystone_url = http://<public Keystone endpoint>:5000/
       rgw_keystone_accepted_roles = member, Member, admin
       rgw_keystone_accepted_admin_roles = ResellerAdmin, swiftoperator
       rgw_keystone_admin_domain = default
       rgw_keystone_admin_project = service
       rgw_keystone_admin_user = swift
       rgw_keystone_admin_password = <password_as_defined_in_the_environment_parameters>
       rgw_keystone_implicit_tenants = true
       rgw_keystone_revocation_interval = 0
       rgw_s3_auth_use_keystone = true
       rgw_swift_versioning_enabled = true
       rgw_swift_account_in_url = true

   Copy to Clipboard Toggle word wrap
   注意

   director 默认在 Identity 服务中创建以下角色和用户：

   • rgw_keystone_accepted_admin_roles: ResellerAdmin, swiftoperator
   • rgw_keystone_admin_domain: default
   • rgw_keystone_admin_project: service
   • rgw_keystone_admin_user: swift

3. 使用与部署相关的任何其他环境文件，使用额外的环境文件部署 overcloud：

   openstack overcloud deploy --templates \
   -e <your_environment_files>
   -e /usr/share/openstack-tripleo-heat-templates/environments/swift-external.yaml
   -e swift-external-params.yaml

验证

1. 以 stack 用户的身份登录 undercloud。

2. 获取 overcloudrc 文件：

   $ source ~/stackrc

3. 验证 Identity 服务(keystone)中是否存在端点：

   $ openstack endpoint list --service object-store
   
   +---------+-----------+-------+-------+---------+-----------+---------------+
   | ID | Region    | Service Name | Service Type | Enabled | Interface | URL |
   +---------+-----------+-------+-------+---------+-----------+---------------+
   | 233b7ea32aaf40c1ad782c696128aa0e | regionOne | swift | object-store | True    | admin     | http://192.168.24.3:8080/v1/AUTH_%(project_id)s |
   | 4ccde35ac76444d7bb82c5816a97abd8 | regionOne | swift | object-store | True    | public    | https://192.168.24.2:13808/v1/AUTH_%(project_id)s |
   | b4ff283f445348639864f560aa2b2b41 | regionOne | swift | object-store | True    | internal  | http://192.168.24.3:8080/v1/AUTH_%(project_id)s |
   +---------+-----------+-------+-------+---------+-----------+---------------+

4. 创建测试容器：

   $ openstack container create <testcontainer>
   +----------------+---------------+------------------------------------+
   | account | container | x-trans-id |
   +----------------+---------------+------------------------------------+
   | AUTH_2852da3cf2fc490081114c434d1fc157 | testcontainer | tx6f5253e710a2449b8ef7e-005f2d29e8 |
   +----------------+---------------+------------------------------------+

5. 创建配置文件以确认您可以将数据上传到容器：

   $ openstack object create testcontainer undercloud.conf
   +-----------------+---------------+----------------------------------+
   | object          | container     | etag                             |
   +-----------------+---------------+----------------------------------+
   | undercloud.conf | testcontainer | 09fcffe126cac1dbac7b89b8fd7a3e4b |
   +-----------------+---------------+----------------------------------+

6. 删除 test 容器：

   $ openstack container delete -r <testcontainer>
