红帽全球峰会4.5. Puppet：为角色自定义 Hieradata
Heat 模板集合包含一组参数，可将额外的配置传递给某些节点类型。这些参数将配置保存为节点的 Puppet 配置的 hieradata。这些参数：
- ControllerExtraConfig
- 添加到所有 Controller 节点的配置。
- NovaComputeExtraConfig
- 添加到所有 Compute 节点的配置。
- BlockStorageExtraConfig
- 添加到所有块存储节点的配置。
- ObjectStorageExtraConfig
- 添加到所有对象存储节点的配置
- CephStorageExtraConfig
- 添加到所有 Ceph Storage 节点的配置
- [ROLE]ExtraConfig
-
要添加到可组合角色的配置。将
[ROLE]替换为可组合角色名称。 - ExtraConfig
- 添加到所有节点的配置。
要添加额外的配置到部署后配置，请在 parameter_defaults 部分中创建一个包含这些参数的环境文件。例如，要将 Compute 主机的保留内存增加到 1024 MB，并将 VNC keymap 设置为日语：
parameter_defaults:
NovaComputeExtraConfig:
nova::compute::reserved_host_memory: 1024
nova::compute::vnc_keymap: ja
parameter_defaults:
NovaComputeExtraConfig:
nova::compute::reserved_host_memory: 1024
nova::compute::vnc_keymap: ja
在运行 openstack overcloud deploy 时包含此环境文件。
重要
您只能定义每个参数一次。后续用法会覆盖以前的值。
