## Background

Since cloud providers develop and release at a different pace compared to the Kubernetes project, abstracting the provider-specific code to the `cloud-controller-manager` binary allows cloud vendors to evolve independently from the core Kubernetes code.
-->
## 背景

由于云驱动的开发和发布与 Kubernetes 项目本身步调不同，将特定于云环境
的代码抽象到 `cloud-controller-manager` 二进制组件有助于云厂商独立于
Kubernetes 核心代码推进其驱动开发。

<!--
The Kubernetes project provides skeleton cloud-controller-manager code with Go interfaces to allow you (or your cloud provider) to plug in your own implementations. This means that a cloud provider can implement a cloud-controller-manager by importing packages from Kubernetes core; each cloudprovider will register their own code by calling `cloudprovider.RegisterCloudProvider` to update a global variable of available cloud providers.
-->
Kubernetes 项目提供 cloud-controller-manager 的框架代码，其中包含 Go
语言的接口，便于你（或者你的云驱动提供者）接驳你自己的实现。
这意味着每个云驱动可以通过从 Kubernetes 核心代码导入软件包来实现一个
cloud-controller-manager；每个云驱动会通过调用
`cloudprovider.RegisterCloudProvider` 接口来注册其自身实现代码，从而更新
记录可用云驱动的全局变量。

### Out of Tree

<!--
To build an out-of-tree cloud-controller-manager for your cloud, follow these steps:
-->
要为你的云环境构建一个 out-of-tree 云控制器管理器：

<!--
1. Create a go package with an implementation that satisfies [cloudprovider.Interface](https://git.k8s.io/kubernetes/pkg/cloudprovider/cloud.go).
2. Use [main.go in cloud-controller-manager](https://github.com/kubernetes/kubernetes/blob/master/cmd/cloud-controller-manager/main.go) from Kubernetes core as a template for your main.go. As mentioned above, the only difference should be the cloud package that will be imported.
3. Import your cloud package in `main.go`, ensure your package has an `init` block to run [cloudprovider.RegisterCloudProvider](https://github.com/kubernetes/kubernetes/blob/master/pkg/cloudprovider/plugins.go#L42-L52).
-->
1. 使用满足 [cloudprovider.Interface](https://git.k8s.io/kubernetes/pkg/cloudprovider/cloud.go)
   的实现创建一个 Go 语言包。
2. 使用来自 Kubernetes 核心代码库的
   [cloud-controller-manager 中的 main.go](https://github.com/kubernetes/kubernetes/blob/master/cmd/cloud-controller-manager/main.go)
   作为 main.go 的模板。如上所述，唯一的区别应该是将导入的云包。
3. 在 `main.go` 中导入你的云包，确保你的包有一个 `init` 块来运行
   [cloudprovider.RegisterCloudProvider](https://github.com/kubernetes/kubernetes/blob/master/pkg/cloudprovider/plugins.go#L42-L52)。

<!--
Many cloud providers publish their controller manager code as open source. If you are creating
a new cloud-controller-manager from scratch, you could take an existing out-of-tree cloud
controller manager as your starting point.
-->
很多云驱动都将其控制器管理器代码以开源代码的形式公开。
如果你在开发一个新的 cloud-controller-manager，你可以选择某个 out-of-tree
云控制器管理器作为出发点。

### In Tree

<!--
For in-tree cloud providers, you can run the in-tree cloud controller manager as a {{< glossary_tooltip term_id="daemonset" >}} in your cluster. See [Cloud Controller Manager Administration](/docs/tasks/administer-cluster/running-cloud-controller/) for more details.
-->
对于 in-tree 驱动，你可以将 in-tree 云控制器管理器作为群集中的
{{< glossary_tooltip term_id="daemonset" text="Daemonset" >}} 来运行。
