ioredis tries to connect to localhost when sentinels are provided

[zizzfizzix]

I'm trying to connect to a sentinel with:

const redisConfig = { host: '10.82.102.71', port: 31691 };
const redisClient = new Redis({
        sentinels: [ redisConfig ],
        name: "redis-cluster"
    });

The debug log of ioredis shows me that it tries to connect to localhost first, though, and I'm getting connect ECONNREFUSED 127.0.0.1:6379:

{"level":"debug","message":"Chosen redis-sentinel config: { host: 10.82.102.71, port: 31691 }"}

} +32ms

I don't think it matters (commented it out) but later on, I'm using the ioredis connection in a bull queue

new Queue("cronJobQueue", {
            createClient: redisClient
        });

I've found the following 2 related issues but mine seems to be a little different: https://github.com/luin/ioredis/issues/796, https://github.com/luin/ioredis/issues/367

My SENTINEL sentinels redis-cluster output is:

1)  1) "name"
    2) "f01bb48b8f7e272bcc016e9511c7ff068bdb1b09"
    3) "ip"
    4) "10.82.98.49"
    5) "port"
    6) "31556"
    7) "runid"
    8) "f01bb48b8f7e272bcc016e9511c7ff068bdb1b09"

   21) "s-down-time"

   23) "down-after-milliseconds"
   24) "1500"
   25) "last-hello-message"
   26) "6326795"
   27) "voted-leader"
   28) "?"
   29) "voted-leader-epoch"
   30) "1"
2)  1) "name"
    2) "8255b32b11d92e6bfa18e3312611610d3fd126b5"
    3) "ip"
    4) "10.82.98.85"
    5) "port"
    6) "31947"
    7) "runid"
    8) "8255b32b11d92e6bfa18e3312611610d3fd126b5"
    9) "flags"
   10) "s_down,sentinel,disconnected"
   11) "link-pending-commands"
   12) "2"
   13) "link-refcount"
   14) "1"
   15) "last-ping-sent"
   16) "6326210"
   17) "last-ok-ping-reply"
   18) "6326834"
   19) "last-ping-reply"
   20) "6326834"
   21) "s-down-time"
   22) "6324616"
   23) "down-after-milliseconds"
   24) "1500"
   25) "last-hello-message"
   26) "6326646"
   27) "voted-leader"
   28) "?"
   29) "voted-leader-epoch"
   30) "1"

And this is my get-master-addr-by-name output:

10.82.102.71:31691> SENTINEL get-master-addr-by-name redis-cluster
1) "10.82.102.71"
2) "31084"

Any help will be much appreciated!

I have the same problem, first two time - redis trying connect to 127.0.0.1:6379 and got error You have triggered an unhandledRejection, you may have forgotten to catch a Promise rejection: Error: connect ECONNREFUSED 127.0.0.1:6379 at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1128:14) but third reconnect - ioredis set correct url what i set in config.

This only happen when i try connect between two docker containers, in local environment - all ok

This is happening to us as well. It seems ioredis is making the assumption that a redis server exists on localhost, when that is not the case and sentinel connection strings are being provided.

@lukeescude how did you fix it? Having the same problem and it's super annoying...
