Use [Helm](https://helm.sh/) to install Service Catalog on your Kubernetes cluster. Up to date information on this process can be found at the [kubernetes-incubator/service-catalog](https://github.com/kubernetes-incubator/service-catalog/blob/master/docs/install.md) repo.

|
使用 [Helm](https://helm.sh/) 在 Kubernetes 集群上安装 Service Catalog。
|
|||
|
|
要获取有关此过程的最新信息，请浏览 [kubernetes-incubator/service-catalog](https://github.com/kubernetes-incubator/service-catalog/blob/master/docs/install.md) 仓库。

|
|
* Understand the key concepts of [Service Catalog](/docs/concepts/service-catalog/).
|
|||
|
|
* Service Catalog requires a Kubernetes cluster running version 1.7 or higher.
|
|||
|
|
* You must have a Kubernetes cluster with cluster DNS enabled.
|
|||
|
|
* If you are using a cloud-based Kubernetes cluster or {{< glossary_tooltip text="Minikube" term_id="minikube" >}}, you may already have cluster DNS enabled.
|
|||
|
|
* If you are using `hack/local-up-cluster.sh`, ensure that the `KUBE_ENABLE_CLUSTER_DNS` environment variable is set, then run the install script.
|
|||
|
|
* [Install and setup kubectl](https://kubernetes.io/docs/tasks/tools/install-kubectl/) v1.7 or higher. Make sure it is configured to connect to the Kubernetes cluster.
|
|||
|
|
* Install [Helm](http://helm.sh/) v2.7.0 or newer.
|
|||
|
|
* Follow the [Helm install instructions](https://github.com/kubernetes/helm/blob/master/docs/install.md).
|
|||
|
|
* If you already have an appropriate version of Helm installed, execute `helm init` to install Tiller, the server-side component of Helm.
|
|||
|
|
-->
|
|||
|
|
* 理解 [Service Catalog](/docs/concepts/service-catalog/) 的关键概念。
|
|||
|
|
* Service Catalog 需要 Kubernetes 集群版本在 1.7 或更高版本。
|
|||
|
|
* 您必须启用 Kubernetes 集群的 DNS 功能。
|
|||
|
|
* 如果使用基于云的 Kubernetes 集群或 {{< glossary_tooltip text="Minikube" term_id="minikube" >}}，则可能已经启用了集群 DNS。
|
|||
|
|
* 如果您正在使用 `hack/local-up-cluster.sh`，请确保设置了 `KUBE_ENABLE_CLUSTER_DNS` 环境变量，然后运行安装脚本。
|
|||
|
|
* [安装和设置 v1.7 或更高版本的 kubectl](https://kubernetes.io/docs/tasks/tools/install-kubectl/)，确保将其配置为连接到 Kubernetes 集群。
|
|||
|
|
* 安装 v2.7.0 或更高版本的 [Helm](http://helm.sh/)。
|
|||
|
|
* 遵照 [Helm 安装说明](https://github.com/kubernetes/helm/blob/master/docs/install.md)。
|
|||
|
|
* 如果已经安装了适当版本的 Helm，请执行 `helm init` 来安装 Helm 的服务器端组件 Tiller。

<!--
|
|||
|
|
Once Helm is installed, add the *service-catalog* Helm repository to your local machine by executing the following command:
|
|||
|
|
-->
|
|||
|
|
安装 Helm 后，通过执行以下命令将 *service-catalog* Helm 存储库添加到本地计算机：
|
|||
|
|
|
|||
|
|
```shell
|
|||
|
|
helm repo add svc-cat https://svc-catalog-charts.storage.googleapis.com

<!--
|
|||
|
|
Check to make sure that it installed successfully by executing the following command:
|
|||
|
|
-->
|
|||
|
|
通过执行以下命令进行检查，以确保安装成功：
|
|||
|
|
|
|||
|
|
```shell
|
|||
|
|
helm search service-catalog
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
<!--
|
|||
|
|
If the installation was successful, the command should output the following:
|
|||
|
|
-->
|
|||
|
|
如果安装成功，该命令应输出以下内容：
|
|||
|
|
|
|||

## 启用 RBAC
|
|||
|
|
|
|||
|
|
<!--
|
|||
|
|
Your Kubernetes cluster must have RBAC enabled, which requires your Tiller Pod(s) to have `cluster-admin` access.
|
|||
|
|
-->
|
|||
|
|
您的 Kubernetes 集群必须启用 RBAC，这需要您的 Tiller Pod 具有 `cluster-admin` 访问权限。
|
|||
|
|
|
|||

If you are using Minikube, run the `minikube start` command with the following flag:
|
|||
|
|
-->
|
|||
|
|
如果您使用的是 Minikube，请使用以下参数运行 `minikube start` 命令：
|
|||
|
|
|
|||
|
|
```shell
|
|||
|
|
minikube start --extra-config=apiserver.Authorization.Mode=RBAC
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
<!--
|
|||
|
|
If you are using `hack/local-up-cluster.sh`, set the `AUTHORIZATION_MODE` environment variable with the following values:
|
|||
|
|
-->
|
|||
|
|
如果您使用 `hack/local-up-cluster.sh`，请使用以下值设置 `AUTHORIZATION_MODE` 环境变量：
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
AUTHORIZATION_MODE=Node,RBAC hack/local-up-cluster.sh -O

By default, `helm init` installs the Tiller Pod into the `kube-system` namespace, with Tiller configured to use the `default` service account.
|
|||
|
|
-->
|
|||
|
|
默认情况下，`helm init` 将 Tiller Pod 安装到 `kube-system` 命名空间，Tiller 配置为使用 `default` 服务帐户。
|
|||
|
|
|
|||
|
|
{{< note >}}
|
|||
|
|
<!--
|
|||
|
|
If you used the `--tiller-namespace` or `--service-account` flags when running `helm init`, the `--serviceaccount` flag in the following command needs to be adjusted to reference the appropriate namespace and ServiceAccount name.
|
|||
|
|
-->
|
|||
|
|
如果在运行 `helm init` 时使用了 `--tiller-namespace` 或 `--service-account` 参数，则需要调整以下命令中的 `--serviceaccount` 参数以引用相应的 namespace 和 ServiceAccount 名称。
