Project Description

What is OSPurge ?

  • ospurge is a standalone client-side tool that aims at deleting all resources, taking into account their interdependencies, in a specified OpenStack project.
  • ospurge ensures in a quick and automated way that no resource is left behind when a project is deleted.
  • ospurge can be used by a cloud administrator, this means a user with the admin role, to cleanup any project or by a non-privileged user to cleanup his own project.

Supported resources

At the moment it is possible to purge the following resources from a project:

  • Floating IP
  • Glance Images
  • Instances
  • Networks
  • Routers
  • Security groups
  • Swift containers
  • Swift objects
  • Volumes / Volume snapshots / Volume backups

Exit codes

The following codes are returned when ospurge exits:

  • Code 0: Process exited successfully
  • Code 1: Something went wrong (check the logs)

Installation

Create a Python 3 virtual environment:

$ python3 -m venv ospurge
$ source ospurge/bin/activate

Install ospurge with pip:

$ python3 -m pip install git+https://git.openstack.org/openstack/ospurge
$ OR, to checkout at commit 328f6

Example usage

To remove a project, credentials have to be provided. The usual OpenStack environment variables can be used. When launching the ospurge script, the project to be cleaned up has to be provided, by using either the --purge-project option or the --purge-own-project option. When the command returns, any resources that belong to the project will have been definitively deleted.

  • Setting OpenStack credentials:
$ export OS_USERNAME=admin
$ export OS_PASSWORD=password
$ export OS_TENANT_NAME=admin
$ export OS_AUTH_URL=http://localhost:5000/v2.0
  • Removing resources:
$ ./ospurge --verbose --purge-project demo

How to extend

Given the ever-widening OpenStack ecosystem, OSPurge can’t support every OpenStack services. We intend to support in-tree, only the ‘core’ services. Fortunately, OSPurge is easily extensible. All you have to do is add a new Python module in the resources package and define one or more Python class(es) that subclass ospurge.resources.base.ServiceResource. Your module will automatically be loaded and your methods called. Have a look at the main.main and main.runner functions to fully understand the mechanism.

Note: We won’t accept any patch that broaden what OSPurge supports, beyond the core services.

How to contribute

OSPurge is hosted on the OpenStack infrastructure and is using Gerrit to manage contributions. You can contribute to the project by following the OpenStack Development workflow.

Start hacking right away with:

$ git clone git://git.openstack.org/openstack/ospurge

Design decisions

  • OSPurge depends on os-client-config to manage authentication. This way, environment variables (OS_*) and CLI options are properly handled.
  • OSPurge is built on top of shade. shade is a simple client library for interacting with OpenStack clouds. With shade, OSPurge can focus on the cleaning resources logic and not on properly building the various Python OpenStack clients and dealing with their not-so-intuitive API.
