Redis error ClusterAllFailedError: Failed to refresh slots cache

[gmussi]

I am facing an issue with the following docker-compose.yml:

  rediscmd:
    image: ghcr.io/joeferner/redis-commander:latest
    restart: unless-stopped
    environment:
      REDIS_HOST: REDACTED.memorydb.eu-central-1.amazonaws.com
      REDIS_PORT: 6379
      REDIS_TLS: true
      REDIS_USERNAME: REDACTED
      REDIS_PASSWORD: REDACTED

It used to work fine before, but after pulling the latest image I am getting:

setUpConnection (C:REDACTED.memorydb.eu-central-1.amazonaws.com:6379:0) Redis error ClusterAllFailedError: Failed to refresh slots cache.
    at tryNode (/redis-commander/node_modules/ioredis/built/cluster/index.js:308:31)
    at /redis-commander/node_modules/ioredis/built/cluster/index.js:325:21
    at Timeout.<anonymous> (/redis-commander/node_modules/ioredis/built/cluster/index.js:662:24)
    at Timeout.run (/redis-commander/node_modules/ioredis/built/utils/index.js:117:22)
    at listOnTimeout (node:internal/timers:571:11)
    at process.processTimers (node:internal/timers:512:7)

Without any changes in infrastructure or configuration.

EDIT: this problem is not present in the previous version (0.8.1)

with latest image RedisCluster support was added. After connection to the Redis server it checks its properties to figure out if we are dealing with a cluster setup -> if yes it reconnects with IORedis Cluster client now.

Its an AWS Memorydb or ElastiCache?

Older image used plain Redis client instead on every connection.

And is it possible to start Redis Commander with the DEBUG=ioredis:* env var set? Maybe the real error was hidden by the "ClusterAllFailedError".

@gmussi i was able to repoduce this error and pushed a fix to latest. Can you please test if it helps you too?

[sseide]

@gmussi added some more code to handle more variants. Any feedback if it is working for you now?

Can you add CLUSTER_NO_TLS_VALIDATION as a supported ENV variable? I don't see it in https://github.com/joeferner/redis-commander/blob/master/docker/entrypoint.sh

After manually configuring the json configuration to:

{
      "label": "local",
      "dbIndex": 0,
      "username": null,
      "password": "",
      "connectionName": "redis",
      "optional": false,
      "clusterNoTlsValidation": true,
      "host": "localhost",
      "port": 6379,
      "isCluster": true,
      "sentinelUsername": null,
      "sentinelPassword": "",
      "clusters": [
        {
          "host": "clustercfg.redis.nwuplk.usw2.cache.amazonaws.com",
          "port": 6379
        }
      ]
    }

I still get

node ./bin/redis-commander

Hi @grantkl ,
at least with running on node directly I was able to connect to a clustered redis instance in AWS and visualize it.

redis-commander  \
  --cluster-no-tls-validation\
  --is-cluster \
  --redis-tls \
  --redis-host <some-aws-cluster-host> \
  --redis-port <some-aws-cluster-port> \
  --redis-password <a-very-secret-password>

So I would expect that to also work in docker with having the CLUSTER_NO_TLS_VALIDATION for docker.
