Devops Meetup
Status: active
Thema: closing the gap between software development and operations
Gestartet: 2010
Organisator: Michael Renner japhy Hannes Schaller
Zuletzt aktualisiert: 2016-10-19


A regular meetup of people interested in DevOps.

DevOps is kind of a new sysadmin buzzword for ways to close the gap between software development and operations; it's what happens when agile development spreads to the server room. We meet to discuss culture, processes, tools and trends that contribute to this field.

DevOps — slides from introductory lightning talk at Metaday #36

There is a mailing list for announcements and discussions, and an experimental page.

Next meetup

Presentation/topic propositions for future

If you have something to present, discuss, show, or ask around about, but don't want to commit to a date yet – here's the place to do it. If you want to hear about something specific, add it here too - maybe there's someone here who can tell about it.

  • Continuous Integration Packaging with FPM -- japhy

FPM is a command-line tool that converts between different package formats (from: local directory, ruby gem, php pear, python module, node.js npm package, deb, rpm; to: local directory, deb, rpm, solaris, tar). The "local directory" pseudo-format allows for easy creation of quick-and-dirty packages that Just Work, short-circuiting all the layers from the Debian Policy Manual all the way up to dh_make with one quick script call. FPM doesn't care about actually building your stuff (as in: unpacking, configuring, compiling, etc). It just takes directory you put it into, and turns it into a package. To prepare the compiled files and put them in the right place first is your job. So is specifying the dependencies - there are no automatic dependencies on dynamically linked libraries.

Workflow for the continuous integration using bits & pieces from the gist:

    • On developer's workstation, "vagrant up" command brings up new VirtualBox VM with clean Debian and sets up a clone of the "packages" repository with a local branch
    • "vagrant ssh" to the VM, go to the packages repo, prepare or modify new package, test it
    • "git push" from the VM to the "develop" branch on the host server
    • "git pull . develop" on the host server's master branch to merge
    • "git push" to central git repo
    • buildbot (continuous integration server) picks up the commit
    • buildbot builds changed package and adds it to the apt repo
    • new package is available to clients via apt-get within minutes from the push.
