Hi,  
can anyone help me with my initial logstash+graylog configuration?

I have 4 docker container in total:  
Graylog+elasticsearch+mongo  
Logstash

So my idea was that I will send all my logs (nxlog inputs) to the Logstash(parser/pipeline) and then results will be sent to Graylog.  
nxlog config

 Module om\_tcp Host 10.50.12.104 Port 5044 OutputType to\_json(); Logstash container conf:` docker run --rm -it -d --user=root --name logstash -p 9600:9600 -p 5044:5044 --link graylogtest:graylog -v C:\tet\:/Config docker.elastic.co/logstash/logstash:7.8.1 logstash -f /Config/logstash.conf`

logstash.conf:

input {  
tcp {  
codec =\> json\_lines { charset =\> CP1252 }  
port =\> "5044"  
tags =\> ["tcpjson"]  
}  
}  
output {  
stdout { codec =\> rubydebug }  
gelf {  
host =\> 'graylog'  
port =\> 5414  
}  
}

Sending inputs directly from the nxlog to the Graylog works perfectly.  
But they are two main problems with the logstash:

1. Gelf as output is not in the default package.
2. I do not receive any inputs...

Thank you for any advice.
