 This page describes the Sumo Kubernetes [Fluentd](http://www.fluentd.org/) plugin.
 
-The plugin runs as a Kubernetes [DaemonSet](http://kubernetes.io/docs/admin/daemons/); it runs an instance of the plugin on each physical host in a cluster. Each plugin instance pulls system, kubelet, docker daemon, and container logs from the host and sends them, in JSON or text format, to an HTTP endpoint on a hosted collector in the [Sumo](http://www.sumologic.com) service.

+By default, the fluentd pods will schedule on, and therefore collect logs from, any worker nodes that do not have a taint and any master node that does not have a taint beyond the default master taint. If you would like to schedule pods on all nodes, regardless of taints, uncomment the following line from fluentd.yaml before applying it.
