@trxn/terraform-service-logstash v2.2.5

Logstash service

Provides a Logstash service that will crawl information from CloudWatch and send it to Elastic Cloud.

This service is based on this Docker image: https://hub.docker.com/repository/docker/tractr/logstash-input-cloudwatch

How it gets information from CloudWatch ?

A user, allowed to read CloudWatch, is created. Its API key and secret are outputted by Terraform.

Configuration example

const api = new LogstashComponent(this, 'logstash', {
  containerConfig: {
    imageTag: '8.3.3',
    environments: {
      XPACK_MONITORING_ENABLED: 'false',
      XPACK_MANAGEMENT_ENABLED: 'true',
      XPACK_MANAGEMENT_ELASTICSEARCH_CLOUD_ID: Secret(),
      XPACK_MANAGEMENT_ELASTICSEARCH_CLOUD_AUTH: Secret(),
      XPACK_MANAGEMENT_PIPELINE_ID: Secret(),
    },
  },
  desiredCount: 1,
  cpu: '1024',
  memory: '1024',
});

XPACK_MANAGEMENT_ELASTICSEARCH_CLOUD_ID, XPACK_MANAGEMENT_ELASTICSEARCH_CLOUD_AUTH and XPACK_MANAGEMENT_PIPELINE_ID must be set in AWS Secrets Manager.

Configuration example

input {
    cloudwatch_logs {
        access_key_id => "${CLOUDWATCH_KEY_ID}"
        secret_access_key => "${CLOUDWATCH_KEY_SECRET}"
        log_group => "production-logs-group"
        region => "us-east-1"
    }
}
filter {
}
output {
    elasticsearch {
        cloud_id => "${XPACK_MANAGEMENT_ELASTICSEARCH_CLOUD_ID}"
        cloud_auth => "${XPACK_MANAGEMENT_ELASTICSEARCH_CLOUD_AUTH}"
        index => "cloudwatch-logs"
    }
}
