Ioredis: connect to sentinel

[ben-yacine]

Hello,

I am trying to use ioredis to connect to my sentinel service under docker which require a password in my config.
Here is my code :
let redisclient = new Redis({
sentinels: [
{ host: "192.168.0.35", port: 26379 }
],
name: "redismaster",
sentinelPassword: "sentinelPassword",
sentinelRetryStrategy: function(times) {
// reconnect after
return Math.max(times * 100, 3000);
}
});

But it doesn't succeed. Here is the log when activate DEBUG=ioredis :

According to the logs, i see that my redis client can connect to sentinel, it also find the real redis server under sentinel mode and select the database. I get the log that redis is connected, but after that, the connection is closed.
Where am i missing ?

PS: i did add also the config snetinel-annouce-ip in case my redis client doesn't recognize the ip of sentinel, but in the logs, it got the good private ip : 192.168.0.35.

thanks for your help.

I found the problem. Because my redis instance also require a password, we must add the attribute password so the second connection to redis instance can be done. this is the new code :
let redisclient = new Redis({ sentinels: [ { host: "192.168.0.35", port: 26379 } ], name: "redismaster", password: "redispassword" sentinelPassword: "sentinelPassword", sentinelRetryStrategy: function(times) { // reconnect after return Math.max(times * 100, 3000); } });
