In order for the Ingress resource to work, the cluster must have an ingress controller running.
|
||
|
||
Unlike other types of controllers which run as part of the `kube-controller-manager` binary, Ingress controllers
|
||
are not started automatically with a cluster. Use this page to choose the ingress controller implementation
|
||
that best fits your cluster.
|
||
|
||
Kubernetes as a project currently supports and maintains [GCE](https://git.k8s.io/ingress-gce/README.md) and
|
||
[nginx](https://git.k8s.io/ingress-nginx/README.md) controllers.
|
||
|
||
-->
|
||
|
||
为了让 Ingress 资源工作，集群必须有一个正在运行的 Ingress 控制器。
|
||
|
||
与其他类型的控制器不同，它们是作为 `kube-controller-manager` 二进制文件的一部分运行的，而 Ingress 控制器不是随集群自动启动的。
|
||
通过此页面可选择最适合您的集群的 ingress 控制器实现。
|
||
|
||
Kubernetes 作为一个项目，目前支持和维护 [GCE](https://git.k8s.io/ingress-gce/README.md) 和
|
||
[nginx](https://git.k8s.io/ingress-nginx/README.md) 控制器。

## Using multiple Ingress controllers
|
||
|
||
You may deploy [any number of ingress controllers](https://git.k8s.io/ingress-nginx/docs/user-guide/multiple-ingress.md#multiple-ingress-controllers)
|
||
within a cluster. When you create an ingress, you should annotate each ingress with the appropriate
|
||
[`ingress.class`](https://git.k8s.io/ingress-gce/docs/faq/README.md#how-do-i-run-multiple-ingress-controllers-in-the-same-cluster)
|
||
to indicate which ingress controller should be used if more than one exists within your cluster.
|
||
|
||
If you do not define a class, your cloud provider may use a default ingress controller.
|
||
|
||
Ideally, all ingress controllers should fulfill this specification, but the various ingress
|
||
controllers operate slightly differently.
|
||
-->
|
||
## 使用多个 Ingress 控制器
|
||
|
||
你可以在集群中部署[任意数量的 ingress 控制器](https://git.k8s.io/ingress-nginx/docs/user-guide/multiple-ingress.md#multiple-ingress-controllers)。
|
||
创建 ingress 时，应该使用适当的
|
||
[`ingress.class`](https://git.k8s.io/ingress-gce/docs/faq/README.md#how-do-i-run-multiple-ingress-controllers-in-the-same-cluster) 注解每个 ingress
|
||
以表明在集群中如果有多个 ingress 控制器时，应该使用哪个 ingress 控制器。
|
||
|
||
如果不定义 `ingress.class`，云提供商可能使用默认的 ingress 控制器。
|
||
|
||
理想情况下，所有 ingress 控制器都应满足此规范，但各种 ingress 控制器的操作略有不同。
|
||
|
||
{{< note >}}
|
||
<!--
|
||
Make sure you review your ingress controller's documentation to understand the caveats of choosing it.
|
||
-->
|
||
确保您查看了 ingress 控制器的文档，以了解选择它的注意事项。
