我正在尝试将我的应用程序连接到Redis，但我得到：

[ioredis] Unhandled error event: Error: connect ECONNREFUSED 127.0.0.1:6379

当我做：

docker exec -it ed02b7e19810 ping test_redis_1 我已经收到所有数据包。

Redis容器也声明：

* Running mode=standalone, port=6379

* Ready to accept connections

（我得到警告，但我不认为与之相关：

Warning: no config file specified, using the default config. In order to specify a config file use redis-server /path/to/redis.conf

WARNING: The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128

这是我的docker-compose.yaml：

version: '3'

services:
  test-service:
      build: .
      volumes:
        - ./:/usr/test-service/
      ports:
        - 5001:3000
      depends_on:
        - redis
  redis:
    image: "redis:alpine"

Docker文件

 FROM node:8.11.2-alpine

 WORKDIR /usr/test-service/

 COPY . /usr/test-service/

 RUN yarn install

 EXPOSE 3000

 CMD ["yarn", "run", "start"]

app.js

const Redis = require('ioredis');
const redis = new Redis();

redis.set('foo', 'bar');
redis.get('foo').then(function (result) {
    console.log(result);
});

我也尝试过redis包装，但仍然无法连接：

 var redis = require("redis"),
     client = redis.createClient();

 client.on("error", function (err) {
     console.log("Error " + err);
 });

得到：

 Error Error: Redis connection to 127.0.0.1:6379 failed - connect ECONNREFUSED 127.0.0.1:6379
