错误：找不到“/config/config.json”。您是否运行过“sequelizeinit”？

我有一个使用Node.js的API项目的Dockerfile-Express.js

api.dockerfile

FROM node:9.3.0

COPY package.json ./

RUN npm set progress=false && npm config set depth 0 && npm cache clean --force

## Storing node modules on a separate layer will prevent unnecessary npm installs at each build
RUN npm i && npm install nodemon --save \
    && npm install pm2 -g \
    && npm install -g sequelize-cli \
    && mkdir /ng-app \
    && chown -R node:node /ng-app \
    && cp -R ./node_modules ./ng-app

# Migration
RUN sequelize db:migrate
RUN sequelize db:seed:all

USER node

WORKDIR /ng-app

COPY . .
RUN mv docker.env .env

CMD ["pm2-runtime", "index.js"]

docker-compose.yaml

version: "2"
services:
  iproject-api:
    build:
      context: ./api
      dockerfile: api.dockerfile
    image: 'iproject-api'
    ports:
      - '3002:3002'
  iproject-web:
    build:
      context: ./web
      dockerfile: web.dockerfile
    image: 'iproject-web:latest'
    ports:
      - '8080:8080'
    links:
      - iproject-api

这是结果，我得到了

**docker-compose build --no-cache**

Sequelize CLI [Node: 9.3.0, CLI: 3.2.0, ORM: 4.31.0]

WARNING: This version of Sequelize CLI is not fully compatible with Sequelize v4. https://github.com/sequelize/cli#sequelize-support

错误：找不到“ /config/config.json”。您是否运行过“ sequelize init”？

一个将如何去调试呢？

这些sequelize命令可能会config/config.json在当前工作目录中查找。在您运行命令时/。您可能希望它/ng-app作为工作目录运行。为此，您可以仅WORKDIR /ng-app在sequalize命令上方移动。

您可以为项目的Sequlize CLI命令创建一个.sequelizerc配置文件，该命令告诉Sequlize在哪里查找配置文件。

    var path = require('path')

module.exports = {
  'config':          path.resolve('server', 'config', 'database.json'),
  'migrations-path': path.resolve('server', 'migrations'),
  'models-path':     path.resolve('server', 'models'),
  'seeders-path':    path.resolve('server', 'seeders'),
}
