Anyone have insight what “skynet.tar.bz2” is?!

  Assuming Google Translate is accurate, it's a server management solution.

  Skynet is a command execution and metric collection layer used in basic cluster ops. Nothing cool to be honest. Essentially it allows you to run a command on all the hosts matching a predicate. This was the easiest way to disrupt a whole datacenter for those who had enough privileges, I did it at least once. Also several times unnoticed bugs in my code shut down literally everything for noticeable periods of time. I've been developing the search orchestration system.

    There's no confirmation about the number of machines the script is going to affect?

      Probably, but irrelevant. What you really need is a confirmation if the sent command will lead to bugs/downtime or not. If you think the command is working 100%, why would you say no to run it on 1000s of machines all at once?

      Yeah, it was extremely easy to fuck up. In some cases though you might have wanted to run something on thousands of hosts to debug a tricky issue. Bad practices, I know.

      It's eventual consistency all the way, so it actually doesn't really know how many machines are there

        That does not necessarily mean it could not provide some useful info about that. E.g. it could run a ping on all eligible machines and show total count of responses in real time for the currently typed filter.
