docker compose容器中的Node.js可以'；不能使用绝对路径访问资源

我正在使用Node.js，我正在尝试对其进行dockerize。有一段代码提供存储在serviceAccount.json文件中的Google应用程序凭据，如下所示：

const googleApplicationCredentials = config.GOOGLE_APPLICATION_CREDENTIALS;
const serviceAccount = require(googleApplicationCredentials);

admin.initializeApp({
    credential: admin.credential.cert(serviceAccount),
    databaseURL: "https://databasename.firebaseio.com"
});

  api:
    build:
      dockerfile: Dockerfile.dev
      context: ./server
    volumes:
      - /app/node_modules
      - ./server:/app
    environment:
      - GOOGLE_APPLICATION_CREDENTIALS="/app/serviceAccount.json"

此凭证文件的路径从docker compose中提取，如下所示：

const googleApplicationCredentials = config.GOOGLE_APPLICATION_CREDENTIALS;
const serviceAccount = require(googleApplicationCredentials);

admin.initializeApp({
    credential: admin.credential.cert(serviceAccount),
    databaseURL: "https://databasename.firebaseio.com"
});

  api:
    build:
      dockerfile: Dockerfile.dev
      context: ./server
    volumes:
      - /app/node_modules
      - ./server:/app
    environment:
      - GOOGLE_APPLICATION_CREDENTIALS="/app/serviceAccount.json"

Docker文件如下：

FROM node:14.14.0-alpine
WORKDIR "/app"
COPY ./package.json ./
RUN npm install
COPY . .
CMD ["npm", "run", "start"]

当我ssh到docker容器时，我可以在工作目录/app下看到servicecomport.json。 但是，当我启动docker componse时，我得到以下错误：

查看docker compose中的卷定义，将/server目录装载到/app。我想这就解释了为什么当您ssh到容器中时它可以工作，而当您

docker组合起来时它不能工作，在后一种情况下，没有装入卷

volumes:
  - /app/node_modules
   # The culprit?
  - ./server:/app

我不太清楚你的建议是什么。服务器是我的主机上的目录，根目录中包含servicecomport.json文件。在docker compose中，此卷将服务器目录从主机映射到docker容器中的/app。当我对用它初始化的容器运行docker compose和SSH时，我看到了该文件，这意味着卷已装入。至少我是这样理解的。但是，在初始化过程中，node.js服务器无法启动，因为它找不到此文件。为了测试它是否与卷相关，我已将卷从docker-compose.yml中完全删除，并将“COPY./servicecomport.json/usr/”添加到Dockerfile中。该文件现在以/usr/servicecomport.json的形式复制到容器中，但节点代码仍然会生成相同的错误，只是位置不同错误：找不到模块'/usr/servicecomport.json''
