第 3 章 创建自定义后端环境文件
您创建的环境文件来配置自定义后端，包含您要定义的每个后端的设置。它还包含与部署自定义后端相关的其他设置。有关环境文件的更多信息，请参阅自定义 Red Hat OpenStack Platform 部署 指南中的环境文件。https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/17.1/html/customizing_your_red_hat_openstack_platform_deployment/assembly_configuring-the-overcloud-with-the-orchestration-service#con_environment-files_understanding-heat-templates
以下示例环境文件定义了两个 NetApp 后端，netapp1 和 netapp2 ：
/home/stack/templates/custom-env.yaml
parameter_defaults: #
CinderEnableIscsiBackend: false
CinderEnableRbdBackend: false
CinderEnableNfsBackend: false
NovaEnableRbdBackend: false
GlanceBackend: file #
ControllerExtraConfig: #
cinder::config::cinder_config:
netapp1/volume_driver: #
value: cinder.volume.drivers.netapp.common.NetAppDriver
netapp1/netapp_storage_family:
value: ontap_7mode
netapp1/netapp_storage_protocol:
value: iscsi
netapp1/netapp_server_hostname:
value: 10.35.64.11
netapp1/netapp_server_port:
value: 80
netapp1/netapp_login:
value: root
netapp1/netapp_password:
value: p@$$w0rd
netapp1/volume_backend_name:
value: netapp1
netapp2/volume_driver: #
value: cinder.volume.drivers.netapp.common.NetAppDriver #
netapp2/netapp_storage_family:
value: ontap_7mode
netapp2/netapp_storage_protocol:
value: iscsi
netapp2/netapp_server_hostname:
value: 10.35.64.11
netapp2/netapp_server_port:
value: 80
netapp2/netapp_login:
value: root
netapp2/netapp_password:
value: p@$$w0rd
netapp2/volume_backend_name:
value: netapp2
cinder_user_enabled_backends: ['netapp1','netapp2'] # - 1
- 以下参数被设置为
false，它会禁用其他后端类型：-
CinderEnableIscsiBackend：其他 iSCSI 后端. -
CinderEnableRbdBackend: Red Hat Ceph。 -
CinderEnableNfsBackend: NFS。 -
NovaEnableRbdBackend: 临时 Red Hat Ceph Storage.
-
- 2
- GlanceBackend 参数设置镜像服务用来存储镜像的内容。支持以下值：
-
file：将镜像存储在每个 Controller 节点上的/var/lib/glance/images上。 -
swift：将对象存储服务用于镜像存储。 -
cinder：使用块存储服务进行镜像存储。
-
- 3
ControllerExtraConfig定义应用到所有 Controller 节点的自定义设置。cinder::config::cinder_config类意味着设置必须应用到 Block Storage (cinder)服务。- 4
netapp1/volume_driver和netapp2/volume_driver设置遵循 section/setting 语法。使用 Block Storage 服务时，每个后端在/etc/cinder/cinder.conf中的其自己的部分中定义。使用netapp1前缀的每个设置在一个新的[netapp1]后端部分定义。- 5
netapp2设置在单独的[netapp2]部分中定义。- 6
value前缀配置前面的设置。- 7
cinder_user_enabled_backends类集合并启用自定义后端。仅在启用了用户的后端使用这个类，特别是cinder::config::cinder_config类中定义的后端。不要使用
cinder_user_enabled_backends来列出您可以与 director 原生启用的后端。这包括支持的 NetApp 或 Dell 设备的 Red Hat Ceph、NFS 和单一后端。例如，如果您启用了 Red Hat Ceph 后端，请不要在cinder_user_enabled_backends中列出它，请通过将CinderEnableRbdBackend设置为true来启用它。
