Hi,  
I'm trying to add redis as a buffer to my stack in docker-compose. My logstash.conf input section is like below:

```auto
input {
  redis {
    host => "redistest"
    port => "6379"
    ssl => false
    data_type => "list"
    key => "All"
    batch_count => 512
    threads => 1
    timeout=> 10
    codec=> "json"
    enable_metric=> false
    db => 0
  }
  udp {
    port => 5001
    codec => json
    }
}

```

In logstash container logs i see info messages like this:

```auto
[2021-11-03T12:16:14,688][INFO][logstash.inputs.redis][main] Registering Redis {:identity=>"redis://@redistest:6379/0 list:All"}

[2021-11-03T12:16:14,709][INFO][logstash.javapipeline][main] Pipeline started {"pipeline.id"=>"main"}

[2021-11-03T12:16:14,872][INFO][logstash.agent] Pipelines running {:count=>1, :running_pipelines=>[:main], :non_running_pipelines=>[]}

[2021-11-03T12:16:14,909][INFO][logstash.inputs.udp][main][94cfabea21d6fd5f7e789580a25bbdeb9c8fd00fe42e823be411985d9d286432] UDP listener started {:address=>"0.0.0.0:5001", :receive_buffer_bytes=>"106496", :queue_size=>"2000"}

[2021-11-03T12:16:15,331][INFO][logstash.agent] Successfully started Logstash API endpoint {:port=>9600}

```

I'm using syslog test message utility tool to test and when I send from port 5001 i receive the logs. However when I use the redis port I dont receive any logs. There's also no error messages or whatsoever in container logs. I am able to monitor traffic on port 6379 via tcpdump so no problems networkwise.  
Things I tried:

- Creating a custom logstash image where i expose the port 6379
- Adding redis dependency to logstash in docker-compose
- Specifying 6379 as both tcp and udp under redis ports in docker-compose

None of these seem to help. Is there something I'm missing? Thanks in advance.
