Reconfigure logstash.conf to transmit data to other destination.

1. Extract logstash.conf from running container:

docker exec -it logstash bash
cd /etc/logstash/
cp logstash.conf /data/elk/logstash.conf
exit

2. Stop T-Pot service

systemctl stop tpot

3. Adjust logstash.conf to your needs:

vi $HOME/tpotce/data/elk/logstash.conf

[...]
# Output section         
output {    
  elasticsearch {                                        
    hosts => ["elasticsearch:9200"]
#    document_type => "doc"                    
  }                   
                 
  if [type] == "Suricata" {         
      file {                             
        file_mode => 0760                                                                                                                                                                                                                        
        path => "/data/suricata/log/suricata_ews.log"
      }             
  }                                    
  # Debug output                       
  #if [type] == "XYZ" {                                                                                                                                                                                                                          
  #  stdout {
  #    codec => rubydebug                
  #  }                                      
  #}                                     
  # Debug output                  
  #stdout {         
  #  codec => rubydebug      
  #}    
                                                  
}
[...]

4. Set correct permissions:

chmod 760 $HOME/tpotce/data/elk/logstash.conf
chown tpot:tpot $HOME/tpotce/data/elk/logstash.conf

5. Adjust docker-compose.yml by adding docker volume for logstash.conf:

vi $HOME/tpotce/docker-compose.yml

[...]
## Logstash service
  logstash:
    container_name: logstash
    restart: always
    depends_on:
      elasticsearch:
        condition: service_healthy
    environment:
     - LS_JAVA_OPTS=-Xms1024m -Xmx1024m
     - TPOT_TYPE=${TPOT_TYPE:-HIVE}
     - TPOT_HIVE_USER=${TPOT_HIVE_USER}
     - TPOT_HIVE_IP=${TPOT_HIVE_IP}
    ports:
     - "127.0.0.1:64305:64305"
    mem_limit: 2g
    image: ${TPOT_REPO}/logstash:${TPOT_VERSION}
    pull_policy: ${TPOT_PULL_POLICY}
    volumes:
     - ${TPOT_DATA_PATH}:/data
     - ${TPOT_DATA_PATH}/elk/logstash.conf:/etc/logstash/logstash.conf
[...]

6. Start T-Pot service

systemctl start tpot
