Question

I am trying to connect to cluster Redis with a valid URL and port I got this error:

Caused by: io.lettuce.core.RedisCommandExecutionException: ERR This instance has cluster support disabled
    at io.lettuce.core.ExceptionFactory.createExecutionException(ExceptionFactory.java:135)

    at io.lettuce.core.protocol.AsyncCommand.complete(AsyncCommand.java:109)

I have cluster-enabled yes

Answer 1

(yeah, this is an old question)

This is typically a result of an attempt to connect using cluster mode to a standalone server (started as a container for development?). IOW, in the code you probably have:

Config config = new Config();
config.useClusterServers() // <<--- Cluster mode
      .addNodeAddress("redis://127.0.0.1:7000");

but should be:

Config config = new Config();
config.useSingleServer() // <<-- Single node mode
      .setAddress("redis://127.0.0.1:7000");
