This tutorial describes how to customize Fluentd logging for a Google Kubernetes Engine cluster. You'll learn how to host your own configurable Fluentd daemonset to send logs to Cloud Logging, instead of selecting the cloud logging option when creating the Google Kubernetes Engine (GKE) cluster, which does not allow configuration of the Fluentd daemon.
