Fluent Bit is a lightweight log processor and forwarder that allows you to collect data and logs from different sources, unify them, and send them to multiple destinations. Tanzu Kubernetes Grid includes signed binaries for Fluent Bit, that you can deploy on the management cluster and on workload clusters to provide a log-forwarding service.

IMPORTANT: Due to significant improvements in the mechanism to deploy extensions in Tanzu Kubernetes Grid 1.2, it is strongly recommended that you upgrade to Tanzu Kubernetes Grid 1.2 before attempting to deploy any extensions.

The Fluent Bit implementation provided in this release of Tanzu Kubernetes Grid allows you to gather logs from management clusters or Tanzu Kubernetes clusters running in vSphere or Amazon EC2, and to forward them to Elastic Search, Kafka, Splunk, or an HTTP endpoint.

First, you deploy Fluent Bit on the cluster from which you want to gather logs. Then, you configure an output plugin on the cluster, depending on whether you use Elastic Search, Kafka, Splunk, or an HTTP endpoint.

IMPORTANT: Tanzu Kubernetes Grid does not support IPv6 addresses. This is because upstream Kubernetes only provides alpha support for IPv6. Always provide IPv4 addresses in the procedures in this section.
