## {{% heading "synopsis" %}}

<!--
Output shell completion code for the specified shell (bash, zsh, fish, or powershell). The shell code must be evaluated to provide interactive completion of kubectl commands.  This can be done by sourcing it from the .bash_profile.

 Detailed instructions on how to do this are available here:

        for macOS:
        https://kubernetes.io/docs/tasks/tools/install-kubectl-macos/#enable-shell-autocompletion
        
        for linux:
        https://kubernetes.io/docs/tasks/tools/install-kubectl-linux/#enable-shell-autocompletion
        
        for windows:
        https://kubernetes.io/docs/tasks/tools/install-kubectl-windows/#enable-shell-autocompletion
-->
输出指定 shell（bash、zsh、fish 或 powershell）的 shell 补全代码。
必须评估 shell 代码才能提供 kubectl 命令的交互式补全，这可以通过从 .bash_profile 中获取它来完成。

有关如何执行此操作的详细说明请参见此处：

- 对于 macOS：
  https://kubernetes.io/docs/tasks/tools/install-kubectl-macos/#enable-shell-autocompletion

- 对于 Linux：
  https://kubernetes.io/docs/tasks/tools/install-kubectl-linux/#enable-shell-autocompletion

- 对于 Windows：
  https://kubernetes.io/docs/tasks/tools/install-kubectl-windows/#enable-shell-autocompletion

<!--     
Note for zsh users: [1] zsh completions are only supported in versions of zsh &gt;= 5.2.
-->
zsh 用户注意事项：[1] zsh 补全仅支持 zsh &gt;= 5.2 版本。

```shell
kubectl completion SHELL

  # Installing bash completion on macOS using homebrew
  ## If running Bash 3.2 included with macOS
  brew install bash-completion
  ## or, if running Bash 4.1+
  brew install bash-completion@2
  ## If kubectl is installed via homebrew, this should start working immediately
  ## If you've installed via other means, you may need add the completion to your completion directory
  kubectl completion bash > $(brew --prefix)/etc/bash_completion.d/kubectl
  
  
  # Installing bash completion on Linux
  ## If bash-completion is not installed on Linux, install the 'bash-completion' package
  ## via your distribution's package manager.
  ## Load the kubectl completion code for bash into the current shell
  source <(kubectl completion bash)
  ## Write bash completion code to a file and source it from .bash_profile
  kubectl completion bash > ~/.kube/completion.bash.inc
  printf "
  # kubectl shell completion
  source '$HOME/.kube/completion.bash.inc'
  " >> $HOME/.bash_profile
  source $HOME/.bash_profile
  
  # Load the kubectl completion code for zsh[1] into the current shell
  source <(kubectl completion zsh)
  # Set the kubectl completion code for zsh[1] to autoload on startup
  kubectl completion zsh > "${fpath[1]}/_kubectl"
  
  
  # Load the kubectl completion code for fish[2] into the current shell
  kubectl completion fish | source
  # To load completions for each session, execute once:
  kubectl completion fish > ~/.config/fish/completions/kubectl.fish
  
  # Load the kubectl completion code for powershell into the current shell
  kubectl completion powershell | Out-String | Invoke-Expression
  # Set kubectl completion code for powershell to run on startup
  ## Save completion code to a script and execute in the profile
  kubectl completion powershell > "$HOME\.kube\completion.ps1"
  Add-Content $PROFILE ". '$HOME\.kube\completion.ps1'"
  ## Execute completion code in the profile
  Add-Content $PROFILE "if (Get-Command kubectl -ErrorAction SilentlyContinue) {
  kubectl completion powershell | Out-String | Invoke-Expression
  }"
  ## Add completion code directly to the $PROFILE script
  kubectl completion powershell >> $PROFILE
```

```shell
# 使用 homebrew 在 macOS 上安装 bash-completion
## 如果运行 macOS 附带的 Bash 3.2
brew install bash-completion
## 或者，如果运行的是 Bash 4.1+
brew install bash-completion@2
## 如果通过 homebrew 安装了 kubectl，Shell 补全应该能够立即起作用
## 如果你通过其他方式安装，则可能需要将新的补全数据添加到补全目录中
kubectl completion bash > $(brew --prefix)/etc/bash_completion.d/kubectl

# 在 Linux 上安装 bash 补全
## 如果 Linux 上未安装 bash-completion，请通过发行版的包管理器安装 "bash-completion" 包。
## 将 bash 的 kubectl 补全代码加载到当前 shell 中
source <(kubectl completion bash)
## 将 bash 补全代码写入文件并从 .bash_profile 中引用之
kubectl completion bash > ~/.kube/completion.bash.inc
printf "
# kubectl shell completion
source '$HOME/.kube/completion.bash.inc'
" >> $HOME/.bash_profile
source $HOME/.bash_profile

# 将 zsh[1] 的 kubectl 补全代码加载到当前 shell 中
source <(kubectl completion zsh)
# 将 zsh[1] 的 kubectl 补全代码设置为在启动时自动加载
kubectl completion zsh > "${fpath[1]}/_kubectl"

# 将 fish[2] 的 kubectl 补全代码加载到当前 shell 中
kubectl completion fish | source
# 要为每个会话都加载补全代码，请执行一次如下命令：
kubectl completion fish > ~/.config/fish/completions/kubectl.fish

# 将 powershell 的 kubectl 补全代码加载到当前 shell 中
kubectl completion powershell | Out-String | Invoke-Expression
# 设置 powershell 的 kubectl 补全代码在启动时运行
## 将补全代码保存到脚本并在配置文件中执行
kubectl completion powershell > "$HOME\.kube\completion.ps1"
Add-Content $PROFILE ". '$HOME\.kube\completion.ps1'"
## 执行配置文件中的补全代码
Add-Content $PROFILE "if (Get-Command kubectl -ErrorAction SilentlyContinue) {
kubectl completion powershell | Out-String | Invoke-Expression
}"
## 直接将补全代码添加到 $PROFILE 脚本
kubectl completion powershell >> $PROFILE
