连接Node js时Redis连接错误

Question

我正在尝试将 Node js 容器与 Redis 容器连接，当我运行 Node-js 容器并尝试连接 Redis 时遇到问题。我尝试了网上的大部分解决方案，仍然无法修复连接被拒绝的问题。

> Node js creating the Redis client: below code works locally good, without the container.

const redis = require('redis')
const redisClient = redis.createClient({
  host: "127.0.0.1",
  port: "6379"
})

> running Redis from the latest image.

docker run -d --name redis -p 6379:6379 redis

> Error:

[nodemon] starting `node index.js`

events.js:377

      throw er; // Unhandled 'error' event

      ^

试试这个

const Redis = require('redis');
const url = `redis://${redis.host}:${redis.port}`;
const usePassword = true;
const client = Redis.createClient({
url,
...(usePassword && { password: "password" })
})
