CI builds tend to generate a *lot* of output. With CruiseControl that’s no problem in itself, but you’ll probably want to purge old build artifacts periodically to avoid maxing out on disc usage.

Here’s a python script for cleaning up your artifacts dir. Posted by Phill (apparently doesn’t like to share his last name). Just put it somewhere sensible and slot into crontab.

#! /usr/bin/env python
# ==== Variables ====
ARTIFACTS_DIR="/opt/cruisecontrol/artifacts/"
NUM_BUILDS_TO_KEEP=10
# ==== End Variables ====

import os

def rm_recursive(path):
        """Removes a directory recursively"""

        for root, dirs, files in os.walk(path, topdown=False):
                for name in files:
                        os.remove(os.path.join(root, name))
                for name in dirs:
                        os.rmdir(os.path.join(root, name))
                #os.rmdir(path)

def delete_old_builds(path):
        """Deletes old builds"""

        builds = os.listdir(path)
        if len(builds) <= NUM_BUILDS_TO_KEEP:
                print "No builds to delete"
                return

        builds.sort()
        builds.reverse()

        i = 0

        for build in builds:
                i += 1
                if i <= NUM_BUILDS_TO_KEEP:
                        continue

                print "Deleting", build
                rm_recursive(os.path.join(path, build))

for file in os.listdir(ARTIFACTS_DIR):
        path = os.path.join(ARTIFACTS_DIR, file)

        if (os.path.isdir(path)):
                delete_old_builds(path)
