How can I set up an ELK stack using Docker for advanced use cases?

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

Yes, please provide a sample Docker Compose file.

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"

What configurations should I add to the Logstash pipeline?

You can define input, filter, and output sections in your Logstash configuration. For example:

input {
  beats {
    port => 5044
  }
}
filter {
  # Add your filters here
}
output {
  elasticsearch {
    hosts => ["elasticsearch:9200"]
  }
}

How do I scale this setup for production?

For production, consider using multiple Elasticsearch nodes, setting up replicas, and configuring persistent storage. You might also want to use orchestration tools like Kubernetes for better management.
