node.js - 在Docker容器中运行Sails.js应用程序时出现“Failed to load gRPC binary module”错误

Question

我有一个本地Docker开发人员环境来构建Sails.js应用程序。这是我的Dockerfile的样子:

FROM node:8.12
LABEL Name=us.gcr.io/my-project/my-app Version=1.0.0

# Container configuration
RUN npm install -g sails@1.0.2 grunt@1.0.3 nodemon@1.18.4
WORKDIR /usr/src/app
COPY ./server/package.json ./package.json
RUN npm install
VOLUME /usr/src/app
EXPOSE 1337

这是我的docker-compose.yml文件的样子:

version: '3.4'

services:
  server:
    image: us.gcr.io/my-project/my-app:latest
    build: .
    environment:
      NODE_ENV: development
      IS_DEV_MACHINE: "yes"
    ports:
      - 1338:1337 # HOST_PORT is 1339 to avoid conflicts with other Sails.js apps running on host
    volumes:
      - ./server:/usr/src/app
    entrypoint: nodemon

  mongodb:
    image: mongo:4
    ports:
      - 27018:27017 # HOST_PORT is 27018 to avoid conflicts with other MongoDB databases running on host
    volumes:
      - ../database:/data/db

通常，一切正常，但是，我最近在应用程序中导入并初始化了 @google-cloud/logging NPM软件包，现在，当我运行 docker-compose up时，出现以下错误:

server_1   | error: Bootstrap encountered an error: (see below)

在上面的错误中，“Bootstrap”是我的Sails.js项目中的bootstrap.js文件，用于初始化@ google-cloud / logging。这就是我在bootstrap.js中初始化记录器的方式:

// Globally required packages
const { Logging } = require('@google-cloud/logging');
const logging = new Logging({ projectId: 'my-project' });
const logger = logging.log('test');

我只是似乎无法弄清楚为什么会发生此错误。我什至尝试将基本的Docker镜像更改为正式的Google App Engine Docker镜像(gcr.io/google-appengine/nodejs)，但这也无济于事。我在任何地方都找不到解决此问题的方法。感谢任何帮助。

您是否有机会在应该在容器(npm install)中完成的本地Mac(darwin)环境中执行了linux？ grpc二进制文件用于错误的OS，因此错误。这通常是在运行Linux Docker容器的本地Mac上发生的。

Expected directory: node-v57-linux-x64-musl
Found: [node-v57-darwin-x64-unknown]

解决方案是在容器中添加rm -fr node_modules并执行npm install。
