Docker compose Logstash integration with VictoriaLogs for docker. High-Availability example

The folder contains the example of integration of logstash with VictoriaLogs Single-Node(s) and vmauth for achieving High Availability.

Check this documentation with a description of the architecture and components.

To spin-up environment run the following command:

docker compose up -d 

To shut down the docker-compose environment run the following command:

docker compose down
docker compose rm -f

The docker compose file contains the following components:

• logstash - logstash is configured to read docker log files, you can find configuration in the pipeline.conf. It writes data in two instances of VictoriaLogs
• VictoriaLogs - the two instances of log database, they accept the data from fluentbit by json line protocol
• vmauth - load balancer for proxying requests to one of VictoriaLogs

Querying the data

• vmui - a web UI is accessible by http://localhost:8427/select/vmui/
• for querying the data via command-line please check these docs

Here is an example of logstash configuration(pipeline.conf):

input {
  file {
    path => "/var/lib/docker/containers/*/*.log"
    start_position => "beginning"
    type => "docker"
    sincedb_path => "/dev/null"
    codec => "json"
    add_field => {
      "path" => "%{[@metadata][path]}"
    }
  }
}

output {
  http {
    url => "http://victorialogs-1:9428/insert/jsonline?_stream_fields=host.name,stream&_msg_field=log&_time_field=time"
    format => "json"
    http_method => "post"
  }
  http {
    url => "http://victorialogs-2:9428/insert/jsonline?_stream_fields=host.name,stream&_msg_field=log&_time_field=time"
    format => "json"
    http_method => "post"
  }
}

Please, note that _stream_fields parameter must follow recommended best practices to achieve better performance.
