Obviously, this approach might not work for everyone, but I like to self-host my repos and use a git hook (post-receive) like this:

  #!/bin/sh
  BUILDDIR=/home/buildhook/.ib-build
  BUILD=`grep build |cut -d" " -f2`
  if [ -n "$BUILD" ]
  then
          touch $BUILDDIR/$BUILD
  fi

And then the buildhook user has a job that runs every minute by cron:

  #!/bin/sh
  BUILDDIR=/home/buildhook/.ib-build
  BUILD=`ls -t $BUILDDIR | head -1`
  if [ -n "$BUILD" ]
  then
          rm -f $BUILDDIR/$BUILD
          (
          echo Building $BUILD on builder...
          ssh builder time ./build $BUILD
          ) 2>&1 | mail -s "Building $BUILD on builder" [e-mail]
  fi

For my use case, on this repo, pushing to a branch with the word "build" in its name will trigger a build of that commit, which builds and packages it into a dpkg, and the build server hosts a private apt repository so I can just `apt-get update; apt-get install blah` on all the servers.

An alternative strategy is pushing to a different repo on a build server, etc.
