Google App Engine:修改云运行环境 [英] Google App Engine: Modify Cloud Run Environment

问题描述

我正在尝试部署一个使用自定义Node.js服务器的Next.js应用程序.

I'm trying to deploy a Next.js app which uses a custom Node.js server.

我想将自定义构建变量注入应用程序:

I want to inject custom build variables into the app:

const NODE_ENV = process.env.NODE_ENV;
const envType = NODE_ENV === `production` ? `production` : `staging`;

const envPath = `./config/${envType}`;
const { env } = require(envPath);

module.exports = {
  env: { ...env },
};

以上文件在构建时运行(yarn build).

The above file is run at build time (yarn build).

问题在于Google App Engine在后台使用Cloud Build.在那里，NODE_ENV始终设置为development.我该如何覆盖NODE_ENV?即如何定制用于Google App Engine gcloud app deploy的Cloud Build?

The issue is that Google App Engine uses Cloud Build behind the scenes. There, the NODE_ENV is always set to development. How can I override the NODE_ENV there; i.e. how can I customize the Cloud Build used for the Google App Engine gcloud app deploy?

由于此问题，我不能只使用Docker .

app.yaml

以下是从app.yaml传递DOGE_ENV变量的输出.如您所见，它是undefined.但是，NODE_ENV是development.

Below is the output of passing a DOGE_ENV variable from app.yaml. As you can see, it is undefined. However, NODE_ENV is development.

也就是说，将以下内容添加到app.yaml无效.

That is, adding the following to app.yaml does not work.

env_variables:
  DOGE_ENV: production

推荐答案

不要使用NODE_ENV，请创建您自己的环境变量并使用该变量:

Don't use NODE_ENV, create your own environment variable and use that:

App.yaml

env_variables:
  ST_ENV: Production

next.config.js

const environment = process.env.ST_ENV;
const envType = environment === `production` ? `production` : `staging`;

const envPath = `./config/${envType}`;
const { env } = require(envPath);

module.exports = {
  env: { ...env },
};
