<!-- overview -->
<!--
 Use the Kubernetes command-line tool, [kubectl](/docs/user-guide/kubectl/), to deploy and manage applications on Kubernetes. Using kubectl, you can inspect cluster resources; create, delete, and update components; look at your new cluster; and bring up example apps.
 -->
在 Kubernetes 上使用 Kubernetes 命令行工具 [kubectl](/zh/docs/reference/kubectl/kubectl/)
部署和管理应用程序。
使用 kubectl，你可以检查集群资源；创建、删除和更新组件；查看你的新集群；并启动实例应用程序。

## {{% heading "prerequisites" %}}

<!--
You must use a kubectl version that is within one minor version difference of your cluster. For example, a v1.2 client should work with v1.1, v1.2, and v1.3 master. Using the latest version of kubectl helps avoid unforeseen issues.
-->
你必须使用与集群小版本号差别为一的 kubectl 版本。
例如，1.2 版本的客户端应该与 1.1 版本、1.2 版本和 1.3 版本的主节点一起使用。
使用最新版本的 kubectl 有助于避免无法预料的问题。

## Verifying kubectl configuration

In order for kubectl to find and access a Kubernetes cluster, it needs a [kubeconfig file](/docs/tasks/access-application-cluster/configure-access-multiple-clusters/), which is created automatically when you create a cluster using kube-up.sh or successfully deploy a Minikube cluster. See the [getting started guides](/docs/setup/) for more about creating clusters. If you need access to a cluster you didn't create, see the [Sharing Cluster Access document](/docs/tasks/access-application-cluster/configure-access-multiple-clusters/).
By default, kubectl configuration is located at `~/.kube/config`.
-->
## 验证 kubectl 配置   {#verifying-kubectl-configuration}

kubectl 需要一个
[kubeconfig 配置文件](/zh/docs/concepts/configuration/organize-cluster-access-kubeconfig/)
使其找到并访问 Kubernetes 集群。
当你使用 kube-up.sh 脚本创建 Kubernetes 集群或者部署 Minikube 集群时，会自动生成 kubeconfig 配置文件。

<!--
Check that kubectl is properly configured by getting the cluster state:
-->
通过获取集群状态检查 kubectl 是否被正确配置：

```shell
kubectl cluster-info
```

<!--
If you see a URL response, kubectl is correctly configured to access your cluster.

If you see a message similar to the following, kubectl is not correctly configured or not able to connect to a Kubernetes cluster.
-->
如果你看到一个 URL 被返回，那么 kubectl 已经被正确配置，能够正常访问你的 Kubernetes 集群。

如果你看到类似以下的信息被返回，那么 kubectl 没有被正确配置，无法正常访问你的 Kubernetes 集群。

```shell
The connection to the server <server-name:port> was refused - did you specify the right host or port?
```

<!--
For example, if you are intending to run a Kubernetes cluster on your laptop (locally), you will need a tool like minikube to be installed first and then re-run the commands stated above.

If kubectl cluster-info returns the url response but you can't access your cluster, to check whether it is configured properly, use:
-->
例如，如果你打算在笔记本电脑（本地）上运行 Kubernetes 集群，则需要首先安装 minikube 等工具，然后重新运行上述命令。

如果 kubectl cluster-info 能够返回 URL 响应，但你无法访问你的集群，可以使用下面的命令检查配置是否正确：

```shell
kubectl cluster-info dump
```

### Introduction

The kubectl completion script for Bash can be generated with the command `kubectl completion bash`. Sourcing the completion script in your shell enables kubectl autocompletion.

However, the completion script depends on [**bash-completion**](https://github.com/scop/bash-completion), which means that you have to install this software first (you can test if you have bash-completion already installed by running `type _init_completion`).
-->
#### 介绍

用于 Bash 的 kubectl 自动补齐脚本可以用 `kubectl completion bash` 命令生成。
在 Shell 环境中引用自动补齐脚本就可以启用 kubectl 自动补齐。

不过，补齐脚本依赖于 [**bash-completion**](https://github.com/scop/bash-completion) 软件包，
这意味着你必须先安装 bash-completion（你可以通过运行 `type _init_completion`）来测试是否
你已经安装了这个软件）。

<!--
### Install bash-completion

bash-completion is provided by many package managers (see [here](https://github.com/scop/bash-completion#installation)). You can install it with `apt-get install bash-completion` or `yum install bash-completion`, etc.

The above commands create `/usr/share/bash-completion/bash_completion`, which is the main script of bash-completion. Depending on your package manager, you have to manually source this file in your `~/.bashrc` file.

To find out, reload your shell and run `type _init_completion`. If the command succeeds, you're already set, otherwise add the following to your `~/.bashrc` file:
-->
### 安装 bash-completion

很多包管理器都提供 bash-completion（参见[这里](https://github.com/scop/bash-completion#installation)）。
你可以通过 `apt-get install bash-completion` 或 `yum install bash-completion` 来安装。

上述命令会创建 `/usr/share/bash-completion/bash_completion`，也就是 bash-completion 的主脚本。
取决于所用的包管理器，你可能必须在你的 `~/.bashrc` 中通过 `source` 源引此文件。

要搞清楚这一点，可以重新加载你的 Shell 并运行 `type _init_completion`。
如果命令成功，一切就绪；否则你就需要将下面的内容添加到你的 `~/.bashrc`
文件中：

```bash
source /usr/share/bash-completion/bash_completion
```

之后，重新加载你的 Shell 并运行 `type _init_completion` 来检查 bash-completion 是否已
正确安装。

<!--
### Enable kubectl autocompletion

You now need to ensure that the kubectl completion script gets sourced in all your shell sessions. There are two ways in which you can do this:
-->
### 启用 kubectl 自动补齐

你现在需要确定在你的所有 Shell 会话中都源引了 kubectl 自动补齐脚本。
实现这点有两种方式：

<!--
- Source the completion script in your `~/.bashrc` file:
-->
- 在 `~/.bashrc` 文件中源引自动补齐脚本

  ```bash
  echo 'source <(kubectl completion bash)' >>~/.bashrc
  ```

<!--
- Add the completion script to the `/etc/bash_completion.d` directory:
-->
- 将自动补齐脚本添加到目录 `/etc/bash_completion.d`：

  ```bash
  kubectl completion bash >/etc/bash_completion.d/kubectl
  ```

<!--
If you have an alias for kubectl, you can extend shell completion to work with that alias:
-->
如果你为 kubectl 命令设置了别名（alias），你可以扩展 Shell 补齐，使之能够与别名一起使用：

```bash
echo 'alias k=kubectl' >>~/.bashrc
echo 'complete -F __start_kubectl k' >>~/.bashrc
```

<!--
- Source the completion script in your `~/.bashrc` file:
-->

<!--
bash-completion sources all completion scripts in `/etc/bash_completion.d`.
-->
{{< note >}}
bash-completion 会自动源引 `/etc/bash_completion.d` 下的所有自动补齐脚本。
{{< /note >}}

<!--
Both approaches are equivalent. After reloading your shell, kubectl autocompletion should be working.
-->
两种方法是等价的。重新加载 Shell 之后，kubectl 的自动补齐应该能够使用了。

### Introduction

The kubectl completion script for Bash can be generated with `kubectl completion bash`. Sourcing this script in your shell enables kubectl completion.

However, the kubectl completion script depends on [**bash-completion**](https://github.com/scop/bash-completion) which you thus have to previously install.

### 介绍

用于 Bash 的 kubectl 自动补齐脚本可以用 `kubectl completion bash` 命令生成。
在 Shell 环境中引用自动补齐脚本就可以启用 kubectl 自动补齐。
不过，补齐脚本依赖于 [**bash-completion**](https://github.com/scop/bash-completion) 软件包，
你必须预先安装。

<!--
There are two versions of bash-completion, v1 and v2. V1 is for Bash 3.2
(which is the default on macOS), and v2 is for Bash 4.1+. The kubectl
completion script **doesn't work** correctly with bash-completion v1 and Bash
3.2. It requires **bash-completion v2** and **Bash 4.1+**. Thus, to be able to
correctly use kubectl completion on macOS, you have to install and use Bash
4.1+
([*instructions*](https://itnext.io/upgrading-bash-on-macos-7138bd1066ba)).
The following instructions assume that you use Bash 4.1+ (that is, any Bash
version of 4.1 or newer).
-->
{{< warning>}}
`bash-completion` 有两个版本，v1 和 v2。
v1 是用于 Bash 3.2 版本的（macOS 上的默认配置），v2 是用于 Bash 4.1 以上版本的。
`kubectl` 补齐脚本 *无法* 在 v1 版本的 bash-completion 和 Bash 3.2 上使用，
需要 **bash-completion v2** 和 **Bash 4.1 以上版本**。
因此，为了在 macOS 上正常使用 kubectl 自动补齐，你需要安装并使用 Bash 4.1+
版本（[*相关指南*](https://itnext.io/upgrading-bash-on-macos-7138bd1066ba)）。
下面的指令假定你在使用 Bash 4.1+（也就是说 Bash 4.1 及以上版本）。
{{< /warning >}}

<!--
### Upgrade Bash

The instructions here assume you use Bash 4.1+. You can check your Bash's version by running:
-->
### 升级 Bash  {#upgrade-bash}

这里的命令假定你使用的是 Bash 4.1+。你可以通过下面的命令来检查 Bash 版本：

```bash
echo $BASH_VERSION
```

<!--
If it is too old, you can install/upgrade it using Homebrew:
-->
如果版本很老，你可以使用 Homebrew 来安装或升级：

```bash
brew install bash
```

<!--
Reload your shell and verify that the desired version is being used:
-->
重新加载 Shell 并验证你使用的版本是期望的版本：

```bash
echo $BASH_VERSION $SHELL
```

<!--
Homebrew usually installs it at `/usr/local/bin/bash`.
-->
Homebrew 通常安装 Bash 到 `/usr/local/bin/bash`。

<!--
### Install bash-completion

{{< note >}}
As mentioned, these instructions assume you use Bash 4.1+, which means you will install bash-completion v2 (in contrast to Bash 3.2 and bash-completion v1, in which case kubectl completion won't work).
{{< /note >}}

You can test if you have bash-completion v2 already installed with `type _init_completion`. If not, you can install it with Homebrew:
-->
### 安装 bash-completion

{{< note >}}
如前所述，这里的指令假定你使用的是 Bash 4.1+，这意味着你会安装 bash-completion
的 v2 版本（与此相对，在 Bash 3.2 版本中的 bash-completion v1 是 kubectl
无法使用的。
{{< /note >}}

你可以通过输入 `type _init_completion` 来测试是否 bash-completion v2 已经安装。
如果没有，可以用 Homebrew 来安装：

```bash
brew install bash-completion@2
```

<!--
As stated in the output of this command, add the following to your `~/.bash_profile` file:
-->
就像命令的输出所提示的，你应该将下面的内容添加到 `~/.bash_profile` 文件中：

```bash
export BASH_COMPLETION_COMPAT_DIR="/usr/local/etc/bash_completion.d"
[[ -r "/usr/local/etc/profile.d/bash_completion.sh" ]] && . "/usr/local/etc/profile.d/bash_completion.sh"
```

<!--
Reload your shell and verify that bash-completion v2 is correctly installed with `type _init_completion`.
-->
重新加载你的 Shell 并运行 `type _init_completion`，验证 bash-completion v2
被正确安装。

<!--
### Enable kubectl autocompletion

You now have to ensure that the kubectl completion script gets sourced in all your shell sessions. There are multiple ways to achieve this:
-->
### 启用 kubectl 自动补齐

你现在需要确保在你的所有 Shell 会话中都源引了 kubectl 自动补齐脚本。
实现这点有两种方式：

<!--
- Source the completion script in your `~/.bashrc` file:
-->
- 在 `~/.bash_profile` 文件中源引自动补齐脚本

  ```bash
  echo 'source <(kubectl completion bash)' >>~/.bash_profile
  ```

<!--
- Add the completion script to the `/etc/bash_completion.d` directory:
-->
- 将自动补齐脚本添加到目录 `/usr/local/etc/bash_completion.d`：

  ```bash
  kubectl completion bash >//usr/local/etc/bash_completion.d/kubectl
  ```

<!--
If you have an alias for kubectl, you can extend shell completion to work with that alias:
-->
- 如果你为 kubectl 命令设置了别名（alias），你可以扩展 Shell 补齐，使之能够与别名一起使用：

  ```bash
  echo 'alias k=kubectl' >>~/.bash_profile
  echo 'complete -F __start_kubectl k' >>~/.bash_profile
  ```

<!--
- If you installed kubectl with Homebrew (as explained [above](#install-with-homebrew-on-macos)), then the kubectl completion script should already be in `/usr/local/etc/bash_completion.d/kubectl`. In that case, you don't need to do anything.

  The Homebrew installation of bash-completion v2 sources all the files in the `BASH_COMPLETION_COMPAT_DIR` directory, that's why the latter two methods work.

In any case, after reloading your shell, kubectl completion should be working.
-->
- 如果你是所有 Homebrew 来安装 kubectl（如[前文](#install-with-homebrew-on-macos)所述）, 
  kubectl 补齐脚本应该已经位于 `/usr/local/etc/bash_completion.d/kubectl` 目录下。
  在这种情况下，你就不用做任何操作了。

<!--
The Homebrew installation of bash-completion v2 sources all the files in the
`BASH_COMPLETION_COMPAT_DIR` directory, that's why the latter two methods work.
-->

The kubectl completion script for Zsh can be generated with the command `kubectl completion zsh`. Sourcing the completion script in your shell enables kubectl autocompletion.

To do so in all your shell sessions, add the following to your `~/.zshrc` file:
-->
Zsh 的 kubectl 补齐脚本可通过 `kubectl completion zsh` 命令来生成。
在 Shell 环境中引用自动补齐脚本就可以启用 kubectl 自动补齐。

```shell
source <(kubectl completion zsh)
```

<!--
If you have an alias for kubectl, you can extend shell completion to work with that alias:
-->
如果你为 kubectl 命令设置了别名（alias），你可以扩展 Shell 补齐，使之能够与别名一起使用：

```shell
echo 'alias k=kubectl' >>~/.zshrc
echo 'complete -F __start_kubectl k' >>~/.zshrc
```

可以将下面的命令添加到你的 `~/.zshrc` 文件的文件头：

```zsh
autoload -Uz compinit
