It looks like there have been a LOT of spaces mistakenly added in the port from our old docs site to the new docs site. You can try this version:

version: '3'
services:
  # MongoDB: https://hub.docker.com/_/mongo/
  mongo:
    image: mongo:4
    container_name: mongodb
    networks:

  # Elasticsearch: https://www.elastic.co/guide/en/elasticsearch/reference/6.x/docker.html
  elasticsearch:

  # Graylog: https://hub.docker.com/r/graylog/graylog/

    networks:

    depends_on:

      - elasticsearch
    ports:
      # Graylog web interface and REST API

I’ve raised this with our technical writing team to have them address it.

thanks a ton for the timely help. It worked.

can you also please let me know where to find the graylog conf file? it is not present in /etc/

infact there is no graylog dir…but graylog is up and running
