kue (reds?) creates always a Redis connection to localhost when requiring

Don’t know if this is kue or reds issue, but it certainly affects kue. Tested on kue master.

Consider following:

var redis = require("redis");                                                                                                                
var client = redis.createClient(1234, "example.com");                           

setTimeout(function() {                                                         
    require("kue");                                                   
}, 1000);                                                                       

client.on("connect", function() {                                               
  console.log("Connected!");                                                    
});                                                                             

It dies immediately after kue is required in the timeout:

Connected!

node.js:134
        throw e; // process.nextTick error, or 'error' event on first tick
        ^
Error: Redis connection to 127.0.0.1:6379 failed - ECONNREFUSED, Connection refused

shell returned 1

Creates a second connection to localhost?

I think the reason is here:

A search is created on require https://github.com/LearnBoost/kue/blob/b2cd5d3393d12e4bdd1c2e654a3ef5eb45e5bf11/lib/queue/job.js#L27

which means new Search on Reds https://github.com/visionmedia/reds/blob/156c046803df6b96fa40e90be26b933f7d324d01/lib/reds.js#L68

which then again means a new Redis client which connects to localhost https://github.com/visionmedia/reds/blob/156c046803df6b96fa40e90be26b933f7d324d01/lib/reds.js#L236

This happens also if you override the createClient function in kue.

I’ve been beating my head against this wall for a full day now. I’m running kue version 0.11 and node 4.5 but still cannot connect to a remote host. here is what my connection looks like:

const config = require(‘./config’); var Kue = require(‘kue’); var queue = Kue.createQueue({ redis: { port: 6379, //process.env.REDIS_PORT, host: ‘DOMAIN_HERE.com’ //process.env.REDIS_HOST, //auth: process.env.REDIS_PASS }, jobEvents: false, disableSearch: true, });

No matter what I try I get the same error back:

events.js:141 throw er; // Unhandled ‘error’ event ^

Error: Redis connection to 127.0.0.1:6379 failed - connect ECONNREFUSED 127.0.0.1:6379 at Object.exports._errnoException (util.js:907:11) at exports._exceptionWithHostPort (util.js:930:20) at TCPConnectWrap.afterConnect as oncomplete

I have tried every example I can find and still nothing… 😦

Any help is greatly appreciated.

@rvbsanjose make sure if you are calling createQueue(…) before accessing kue.app express application, and also try with disableSearch: true. Finally provide the code so that I can fix it, however I don’t believe it is a bug.
