无法容器化NestJS微服务

Question

我正在尝试将NestJS微服务容器化。当我直接运行该服务时，它会按预期运行。但是当我构建一个镜像并运行它时，我得到了这个错误：

9:09:10 AM - Starting compilation in watch mode...

9:09:17 AM - Found 0 errors. Watching for file changes.
/var/www/notification-service/node_modules/twilio/lib/rest/Twilio.js:139
    throw new Error('username is required');
    ^

    at Module.load (internal/modules/cjs/loader.js:1100:32)

当我运行它的时候没有将它装入容器。它似乎开始得很好：

Twilio开发者的布道者在这里。

您得到的错误是因为您没有为Twilio库提供用户名(帐户SID或API密钥)。Twilio通常建议您在环境变量中设置帐户凭据，以便它们不是源代码的一部分。我没有使用容器化应用程序的经验，但我的猜测是，当您构建和运行容器时，它不再使用相同的环境变量运行。

因此，您需要找到一种方法将帐户凭据安全地放入容器中，以便您的应用程序可以读取它们。从您提供的错误/运行日志中，我对您的应用程序了解不多，但希望这能让您走上正确的道路。
