Google Gets Slack with Software Updates

Posted by ryuzaki0 on from the showing-off-your-toys dept.

An anonymous reader writes "While Google's open source project titled 'Slack' was released over a year ago, last week's Australian Unix Users Group Conference marks the first time that Google has ever discussed the system in public. Corporate systems administrator Michael Still helped to illuminate a little bit about how Google uses Slack and how their network of computers fits together. From the article: '"Slack is a source deployment system and it's the way we install applications on servers," Still said, adding Slack is based around a centralized configuration repository which is then deployed onto selected machines in a "pull" method. Each of the "worker" machines asks for its new configuration regularly or when a manual command is run.'"

    Before anybody says "Hey! Where's the source?!", let me just provide a link right now:

    Do me a favor and don't destroy sundell's server, or he's likely to hurt me :-P

    Short Description:

    slack is a configuration management system designed to appeal to lazy
    admins (like me). It's an evolution from the usual "put files in some
    central directory" that is faily common practice. It's descended from an
    earlier system I also wrote, called "subsets", and uses a multi-stage
    rsync to fix some of the problems I had there.

    Basically, it's a glorified wrapper around rsync.

    See the file COPYING.

    Documentation:
    Not much, but there's some in doc/

    Reporting problems:
    Send an email to <sundell (at gmail.com)>. Probably want to put
    "slack" in the subject and be patient for replies. :)

    FWIW, the name is an acronym: SLACK - Sysadmins' Lazy Auto-Configuration Kit
