ubuntu - Dyno 元数据未显示在 "env"输出中

Question

我正在尝试在 this guide 之后获取 Heroku 上的 dyno 元数据在 Google Cloud Shell 上，但它不显示 dyno 元数据。

当我输入以下命令时:

heroku labs:enable runtime-dyno-metadata -a app_name

它显示以下消息:

Enabling runtime-dyno-metadata for <app name>... done

但是当我运行 env命令它不显示测功元数据。

我期待这样的事情:

env

但它显示如下:

如何动态访问测功元数据？

Answer 1

该输出看起来像是用于您的 Google shell 的。

Heroku 元数据环境变量不会出现在您的本地 shell 中，而是出现在 dyno 的环境中。您的应用应该能够访问它们。

尝试在 Heroku 上运行它，例如通过

heroku run env
