为kubectl增加插件

先下载配置文件和相应的tar包,并对tar包解压,释放出可执行文件:

wget https://storage.googleapis.com/krew/v0.2.1/krew.tar.gz
wget https://storage.googleapis.com/krew/v0.2.1/krew.yaml
tar -zxvf krew.tar.gz

Installing plugin: krew

CAVEATS:

\

 |  krew is now installed! To start using kubectl plugins, you need to add

 |  krew's installation directory to your PATH:

 |

 |    * macOS/Linux:

 |      - Add the following to your ~/.bashrc or ~/.zshrc:

 |          export PATH="${KREW_ROOT:-$HOME/.krew}/bin:$PATH"

 |      - Restart your shell.

 |

 |    * Windows: Add %USERPROFILE%.krew\bin to your PATH environment variable

 |

 |  Run "kubectl krew" to list krew commands and get help.

 |  You can find documentation at https://github.com/GoogleContainerTools/krew.
