Re: "Chaos monkey" for mesos?
There's no way to kill a single task through the Mesos control surfaces, but if you let the "chaos" framework launch tasks as a privileged user, you can run wild.

Re: "Chaos monkey" for mesos?
Sorry, ignore my first question. A framework can obviously kill tasks. I was just unsure as to whether it can kill foreign tasks, which leaves only my second question.

Re: "Chaos monkey" for mesos?
Appreciate all the responses here. I'll look into `mesos-execute`. I was thinking about the framework idea in passing but my mesos knowledge isn't up to scratch yet, so I haven't been able pursue it yet. There are many questions in my mind w.r.t designing this as a framework: * Doesn't a framework only receive offers from mesos and launch tasks? How would a framework kill tasks? Can it also kill slaves? * Is it legal in mesos for one framework to kill tasks belonging to another framework? Thanks.

Re: "Chaos monkey" for mesos?
I think you could approximate that tool's behavior with some scripting plus `mesos-execute` (ships with the distribution) or by writing a really simple framework that just turns things off.

Re: "Chaos monkey" for mesos?
Thanks. Craig and David. I'm curious about the design and use of that tool. Based on the video, it looks close to what I hope to do. A web search didn't yield any results about it, however. Does anyone here know more about the dcos chaos tool? Thanks again.

Re: "Chaos monkey" for mesos?
The DCOS tutorial mentions a chaos tool at the end of the video. Not sure if that's what your looking for, but it might be something to follow up on somehow. https://mesosphere.com/learn/ David Wood Computing Systems for Wireless Networks IBM TJ Watson Research Center daw...@us.ibm.com 914-945-4923 (office), 914-396-6515 (mobile) From: Srikanth Viswanathan <srikant...@gmail.com> To: user@mesos.apache.org Date: 02/25/2016 12:01 PM Subject: "Chaos monkey" for mesos?

"Chaos monkey" for mesos?
Has there been any work done to develop a "chaos monkey <https://github.com/Netflix/SimianArmy/wiki/Chaos-Monkey>" analogue for Mesos? I have been researching on how to write one, but I wanted to know if there's any work already available that I can take a look at for comparison, and possibly re-use. The end goal would be something loaded into Mesos or separate from Mesos that randomly kills tasks.
