This script can also be used to cleanup OpenStack resources with a name matching a given regular expression. +Resources in a given selection set are deleted along with their dependencies in the correct order. For example to delete a router you need to delete first all the interfaces before you can delete the router. To delete a volume you need to first detach the volume (if attached) before it can be deleted. +Furthermore, some resource deletions require dependent resources to be actually deleted first (which can tale more or less time) before they can succeed. A volume detach command for example can take time and if you do not want long enough the volume deletion will fail. +The script takes care of all these dependencies and timing considerations. + +The current version of the script can delete the following resources with a name that matches a given regular expression: + +* Storage + + * volume (detach and delete) + +* Compute + + * instances + * flavors + * key pairs + +* Network + + * security groups + * floating IPs + * routers (including all associated interfaces) + * networks + +* Keystone: + + * users + * tenants + +How to Select Resources to Delete +--------------------------------- + +Resource list (--file ) +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +KloudBuster generates a cleanup log file when it exits without deleting all resources. + +This file is a text file with 1 row per resource, where each row has the following format>:: + + ||) +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +If no cleanup log file is provided, resources are discovered from OpenStack and selected using a regular expression on the resource name (--filter ). +You can specify any valid python regular expression to select the resource by name. +If you do not specify a cleanup log file nor a filter, the script will discover all resources with a name starting with "KB" which is the prefix for all KloudBuster resources. + +Some examples (refer to the python regex documentation for a detailed description of regular expressions): + ++--------------------+-----------------------------------------------------------------+ +| Regular expression | (default) any OpenStack resource with a name starting with "KB | ++====================+=================================================================+ +| ext$ | any OpenStack resource with a name starting ending with "ext" | ++--------------------+-----------------------------------------------------------------+ +| .*net | any resource with a name containing "net" in any position | ++--------------------+-----------------------------------------------------------------+ +| glance|neutron | any resource with a name starting with "glance" or "neutron" | ++--------------------+-----------------------------------------------------------------+ + + + +.. warning:: + + you can of course also specify '.\*' to list all resources but you probably do not want to delete all of them! + +Credentials (RC) file (--rc ) +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Specify the openrc file (downloaded from the Horizon API Access page) to provide the credentials to access OpenStack. +Alternatively you can also source that file from the shell before invoking the force_cleanup.py script. + +Dry Run (--dryrun) +^^^^^^^^^^^^^^^^^^ + +The script also provides a dry run mode, meaning that you can just check what the script would do without actually deleting anything. + +Installation and Dependencies +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +The script is available in the OpenStack KloudBuster repository under kloudbuster/force_cleanup.py +If you need to run the script outside of the usual KloudBuster installation, the script requires the usual OpenStack python client libraries and requires credentials.py (from the kloudbuster module).
