Logstash setting output to elasticsearch

[Juneyoung_Oh]

I am using logstash to store and analyze logs of an web application.

But some reason logstash keep failing to send data to elasticsearch.
The error message says "cannot create pipeline".

However, I do not see what makes it fail.
Follow is my configuration for logstash

input {
  file {
    path => "/etc/logstash/logs/log*.json"
  }
}

filter {
}

output {
  elasticsearch {
    host => ["localhost:9200"]
    stdout { codec : rubydebug }
    index => "logstash"
  }
}

I thought logstash will read log*.json files and send it to elasticsearch, it did not.
What should I do to fix this pipe?

FYI, I am using sebp/elk docker image to do this. So all elk are in the same container.

Hi,
eleasticsearch output plugin don't have any stdout parameter,
try

output {
  elasticsearch {
    hosts => ["localhost:9200"]
    index => "logstash"
  }
}
