How can I set up an advanced ELK stack logging system using Docker?

To set up an advanced ELK stack logging system using Docker, you'll need to create a Docker Compose file that defines the services for Elasticsearch, Logstash, and Kibana. Would you like a sample configuration?

Yes, please provide a sample Docker Compose configuration.

Here's a basic example:

version: '3'
services:
  elasticsearch:
    image: elasticsearch:7.10.0
    environment:
      - discovery.type=single-node
    ports:
      - "9200:9200"
  logstash:
    image: logstash:7.10.0
    ports:
      - "5044:5044"
    volumes:
      - ./logstash.conf:/usr/share/logstash/pipeline/logstash.conf
  kibana:
    image: kibana:7.10.0
    ports:
      - "5601:5601"

Would you like to know how to configure Logstash?

Yes, how do I configure Logstash to receive logs?

You can configure Logstash by creating a logstash.conf file. Here's a simple example:

input {
  beats {
    port => 5044
  }
}
output {
  elasticsearch {
    hosts => ["elasticsearch:9200"]
    index => "logs-%{+YYYY.MM.dd}"
  }
}

This configuration listens for logs on port 5044 and sends them to Elasticsearch. Do you need help with anything else?
