自动化gcloud组件更新

Question

如何在shell脚本中以编程方式更新gcloud组件？

呼叫gcloud components update需要用户输入,例如:

$ gcloud components update

The following components will be installed:
--------------------------------------------
| kubectl (Linux, x86_64) | 1.0.1 | 4.5 MB |
--------------------------------------------

For the latest release notes, please visit:

Do you want to continue (Y/n)? 

我无法找到gcloud强制执行更新的论据.

你正在寻找 --quiet国旗.

从 gcloud --help:

 --quiet, -q
    Disable all interactive prompts when running gcloud commands. If input
    is required, defaults will be used, or an error will be raised.

这通常是您需要非交互式上下文的标志.

您还可以将CLOUDSDK_CORE_DISABLE_PROMPTS环境变量设置为非空值:

export CLOUDSDK_CORE_DISABLE_PROMPTS=1
gcloud components update # This works for all gcloud commands
