  3. DaemonSet Update (if using YAML):

  4. Open your existing DaemonSet configuration.
  5. Change the container image to “amazon/aws-for-fluent-bit:3.0.0”.

  6. Apply your changes using kubectl apply -f <your_deployment_yaml>.

  7. Verify the Deployment: Ensure all nodes running Fluent Bit reflect the updated version by executing kubectl get pods -n <namespace>.

Best Practices for Using AWS for Fluent Bit

  • Log Filtering: Use Fluent Bit’s filter capabilities to process only the required logs, reducing noise and focusing on actionable insights.
  • Implement Monitoring: Use Amazon CloudWatch to monitor log metrics from your containers for optimized performance.
  • Secure Configuration: Always enforce TLS and maintain strict access controls for log data. Consider utilizing IAM policies for better security management.

Integrating AWS for Fluent Bit with CloudWatch

Integrating AWS for Fluent Bit with Amazon CloudWatch Logs provides a powerful logging solution for your containers. Here’s how to set it up:

  1. Set Up Log Group: Create a log group in the CloudWatch console where the logs will be stored.

  2. Define Outputs in Fluent Bit: In your Fluent Bit configuration file, specify the CloudWatch output plugin with the log group name you’ve created.
    ini
    [OUTPUT]
    Name cloudwatch
    Match *
    region us-west-2
    log_group_name YourLogGroup
    log_stream_prefix YourLogStreamPrefix

  3. Monitor Logs: Use the CloudWatch Logs console to search and analyze logs generated by your containerized applications.

Exploring OpenTelemetry Support

The inclusion of native OpenTelemetry (OTel) support in AWS for Fluent Bit simplifies logging across distributed systems. Here’s how to implement OTel logging:

  1. Enable OpenTelemetry: In your Fluent Bit configuration, add the appropriate sections for OTel, configuring your desired settings for metrics and traces.

  2. Forwarding OTel Logs: Utilize the configuration shown below to direct traces and logs efficiently:
    ini
    [OUTPUT]
    Name otel
    Match *
    OTel_Protocol http
    Endpoint your_otlp_endpoint

  3. Authentication: Use the AWS SigV4 method for authenticating your logs, maintaining ease of use without the requirements of additional sidecars.
