app.js restapi 转 graphql 
require(‘babel-polyfill‘);
const express = require(‘express‘);
const app = express();
const graphqlHTTP = require(‘express-graphql‘);
const graphQLSchema = require(‘./lib‘); // 类型映射

const proxyUrl = ‘https://petstore.swagger.io/v2‘;
const pathToSwaggerSchema = `${__dirname}/api/s.json`; // swagger api 描述
const customHeaders = {
  Authorization: ‘Basic YWRkOmJhc2ljQXV0aA==‘
};

graphQLSchema(pathToSwaggerSchema, proxyUrl, customHeaders).then(schema => {
  app.use(‘/graphql‘, graphqlHTTP(() => {
    return {
      schema,
      graphiql: true
    };
  }));

  app.listen(3009, ‘0.0.0.0‘, () => {
    console.info(‘http://localhost:3009/graphql‘);
  });
}).catch(e => {
  console.log(e);
});

Dockerfile  docker 镜像构建

FROM dalongrong/node-yarn
WORKDIR /app
COPY . /app
RUN yarn install
EXPOSE 3009
ENTRYPOINT [ "yarn","start" ]

docker-compose.yaml  docker-compose 运行文件
version: "3"
services:
   g:
    build: ./
    image: dalongrong/swagger-graphql
    ports:
    - "3009:3009"

docker-compose build

docker-compose up -d
