ioredis client not able to connect in cluster mode with TLS enabled #1800

Open prameet-verma opened 10 months ago

prameet-verma commented 10 months ago

I am running my NextJS application which uses AWS Elasticahe Redis Cluster on server side. Now I am trying use a different redis cluster but in TLS mode with these settings:

My code:

import Redis from 'ioredis';
// Use redis adapter if available
try {
  console.log('Starting redis cache in cluster');
  const cluster = new Redis.Cluster( 
    [

      {
        // url: 'rediss://clusterurl.mcy1ro.usw2.cache.amazonaws.com:6379',
        host: 'clusterurl.mcy1ro.usw2.cache.amazonaws.com',
        port: 6379,
        // tls: true,
        // ssl: true
      },
    ],
    {
      //https://github.com/redis/ioredis#special-note-aws-elasticache-clusters-with-tls
      dnsLookup: (address, callback) => callback(null, address),
      lazyConnect: true,
      redisOptions: {
        tls: {
          checkServerIdentity: () => undefined,
        },
        // ssl: true,
      },
    }
  );
  cluster.on('error', (error) => console.log('error listener', error));
  // This will throw if not able to connect on startup
  cluster
    .connect()
    .then(() => {
      console.log('Cluster Connected Successfully');
      cluster.set('prameet', 'localhost');
    })
    .catch((err) => console.error('Catch cluster', err));
  cluster.set('prameet', 'localhost').then(()=> console.log('Cluster value set Successfully'));
} catch (error) {
  console.error('try-catch', error);
}

I have followed the documentation https://github.com/redis/ioredis#special-note-aws-elasticache-clusters-with-tls.
