If you are using a released version of Kubernetes, you should refer to the docs that go with that version.
The latest 1.0.x release of this document can be found [here](http://releases.k8s.io/release-1.0/docs/user-guide/logging-demo/README.md).Documentation for other releases can be found at releases.k8s.io.
This directory contains two pod specifications which can be used as synthetic logging sources. The pod specification in synthetic_0_25lps.yaml describes a pod that just emits a log message once every 4 seconds. The pod specification in synthetic_10lps.yaml describes a pod that just emits 10 log lines per second.
See logging document for more details about logging. To observe the ingested log lines when using Google Cloud Logging please see the getting started instructions at Cluster Level Logging to Google Cloud Logging. To observe the ingested log lines when using Elasticsearch and Kibana please see the getting started instructions at Cluster Level Logging with Elasticsearch and Kibana.
