ERROR [RedisModule] default: All sentinels are unreachable. Retrying from scratch after 160ms.

Trying to set up Sentinel, but I am having some issues.

My docker-compose.yaml:

  redis-sentinel:
    image: bitnami/redis-sentinel:latest
    restart: always
    ports:
      - 26379:26379
    networks:
      - nestjs-network
    environment:
      - REDIS_MASTER_HOST=redis
  redis:
    image: 'bitnami/redis:latest'
    environment:
      - ALLOW_EMPTY_PASSWORD=yes
    networks:
      - nestjs-network
    ports:
      - 6379:6379

Sentinel seems to be up and running:

My configuration:

return {
	readyLog: true,
	commonOptions: {
		name: 'mymaster',
		sentinels: [
			{
				host: "localhost", // I am running npm locally (not in docker)
				port: 26379,
			},
		],
	},
	config: [
		{
			// get master node from the sentinel group
			role: 'master',
		},
		{
			// get a random slave node from the sentinel group
			role: 'slave',
		},
	],
}

But I am getting error:

[Nest] 7506  - 04/10/2022, 5:08:21 PM   ERROR [RedisModule] default: All sentinels are unreachable. Retrying from scratch after 130ms.
Error: All sentinels are unreachable. Retrying from scratch after 130ms.

What am I missing here?

your compose config does not specify slave nodes.

try this:

{
    readyLog: true,
    commonOptions: {
        name: 'mymaster',
        sentinels: [
            {
                host: 'localhost', // I am running npm locally (not in docker)
                port: 26379
            }
        ]
    },
    config: [
        {
            // get master node from the sentinel group
            role: 'master'
        }
    ]
}

Yes, I can share with you my config when I’m back at the computer
