所以我正在编写一个节点应用程序,而我的docker-compose.yml看起来像:
version: '2'
services:
redis:
image: "redis:latest"
web:
build: .
ports:
- "3000:3000"
volumes:
- .:/app
links:
- redis
emailworker:
build: .
env_file:
- ./.env
command: node ./lib/workers/email.js
volumes:
- .:/app
links:
- redis
smsworker:
build: .
env_file:
- ./.env
command: node ./lib/workers/sms.js
volumes:
- .:/app
links:
- redis
非常简单,一个网络服务器,以及两个处理电子邮件和短信作业的工作人员。一切都很棒,直到今天下午,似乎没有什么变化,但是当我的应用程序启动时,我无法再连接到redis容器。我运行docker-compose up
并尝试使用kue
节点模块连接到redis时出现以下错误:
Error: Redis connection to 127.0.0.1:6379 failed - connect ECONNREFUSED 127.0.0.1:6379
at Object.exports._errnoException (util.js:1022:11)
at exports._exceptionWithHostPort (util.js:1045:20)
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1087:14)
我与redis的kue
连接如下:
const kue = require('kue'),
queue = kue.createQueue({
root: __dirname,
redis: {
host: 'redis',
port: 6379
}
});
queue.on('error', err => {
console.log('QUEUE ERROR: ', err);
});
我在这里出错的任何想法?我昨晚刚刚设置了这个,电子邮件很高兴被发送,就像我提到的那样,唯一可以改变的是Web服务中的应用程序代码。我在Mac上进行开发,如果它有所作为,并拥有最新版本的docker和docker-compose。执行docker ps
后docker-compose up
显示:
