How can I set up log aggregation with Docker and Fluentd?

To set up log aggregation with Docker and Fluentd, you need to configure Fluentd as a logging driver in your Docker containers.

What configuration do I need for Fluentd?

You need to create a Fluentd configuration file that specifies the input sources and output destinations for your logs.

Can you provide an example of a Fluentd configuration file?

Sure! Here's a basic example:

<source>
  @type docker
  path /var/lib/docker/containers/*.log
  pos_file /var/log/fluentd-docker.log.pos
  tag docker.*
</source>

<match docker.**>
  @type elasticsearch
  host elasticsearch
  port 9200
  logstash_format true
</match>
