k8s安装之eventrouter.yaml

Posted 2021-12-02 aguncn

k8s的heapster项目中止以后, 事件收集的项目,就推荐使用https://github.com/heptiolabs/eventrouter项目了

Eventrouter

This repository contains a simple event router for the Kubernetes project. The event router serves as an active watcher of event resource in the kubernetes system, which takes those events and pushes them to a user specified sink. This is useful for a number of different purposes, but most notably long term behavioral analysis of your workloads running on your kubernetes cluster.

Goals

This project has several objectives, which include:

• Persist events for longer period of time to allow for system debugging
• Allows operators to forward events to other system(s) for archiving/ML/introspection/etc.
• It should be relatively low overhead
• Support for multiple sinks should be configurable

NOTE:

By default, eventrouter is configured to leverage existing EFK stacks by outputting wrapped json object which are easy to index in elastic search.
