Hello, everyone  
I use logstash with custom docker image following this doc: [https://www.elastic.co/guide/en/logstash/current/docker.html](https://www.elastic.co/guide/en/logstash/current/docker.html).  
I only change content of pipeline config as follow:

input {  
redis {  
batch\_count =\> 1  
data\_type =\> "list"  
key =\> "logstash-list"  
host =\> "192.168.154.136"  
port =\> 6380  
threads =\> 5  
codec =\> "plain"  
}  
}

output {  
stdout {}  
}

But I got the following error:  
[2017-05-03T04:21:28,028][INFO][logstash.outputs.elasticsearch] Running health check to see if an Elasticsearch connection is working {:healthcheck\_url=\>[http://logstash\_system:xxxxxx@localhost:9200/](http://logstash_system:xxxxxx@localhost:9200/), :path=\>"/"}  
[2017-05-03T04:21:28,199][WARN][logstash.outputs.elasticsearch] Attempted to resurrect connection to dead ES instance, but got an error. {:url=\>#\<URI::HTTP:0x26f289c URL:[http://logstash\_system:xxxxxx@localhost:9200/\_xpack/monitoring/?system\_id=logstash&system\_api\_version=2&interval=1s](http://logstash_system:xxxxxx@localhost:9200/_xpack/monitoring/?system_id=logstash&system_api_version=2&interval=1s)\>, :error\_type=\>LogStash::Outputs::ElasticSearch::HttpClient::Pool::HostUnreachableError, :error=\>"Elasticsearch Unreachable: [[http://logstash\_system:xxxxxx@localhost:9200/](http://logstash_system:xxxxxx@localhost:9200/)][Manticore::SocketException] Connection refused (Connection refused)"}

I didn't config output with elastic search. I'll appreciate if anyone can help me out, thanks
