ospurge is a standalone, client-side, Python script 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 (with the admin role)
to cleanup any project or by a non-privileged user to cleanup his own
project.
Create a Python virtual environment (requires package virtualenvwrapper):
$ mkvirtualenv ospurge
Install ospurge:
$ pip install ospurge
The script is installed and can be launched:
$ ospurge -h
Available options can be displayed by using ospurge -h:
$ ospurge -h
usage: ospurge [-h] [--verbose] [--dry-run] [--dont-delete-project]
[--region-name REGION_NAME] [--endpoint-type ENDPOINT_TYPE]
--username USERNAME --password PASSWORD --admin-project
ADMIN_PROJECT --auth-url AUTH_URL
[--cleanup-project CLEANUP_PROJECT] [--own-project]
[--insecure]
Purge resources from an Openstack project.
optional arguments:
-h, --help show this help message and exit
--verbose Makes output verbose
--dry-run List project's resources
--dont-delete-project
Executes cleanup script without removing the project.
Warning: all project resources will still be deleted.
--region-name REGION_NAME
Region to use. Defaults to env[OS_REGION_NAME] or None
--endpoint-type ENDPOINT_TYPE
Endpoint type to use. Defaults to
env[OS_ENDPOINT_TYPE] or publicURL
--username USERNAME If --own-project is set : a user name with access to
the project being purged. If --cleanup-project is set
: a user name with admin role in project specified in
--admin-project. Defaults to env[OS_USERNAME]
--password PASSWORD The user's password. Defaults to env[OS_PASSWORD].
--admin-project ADMIN_PROJECT
Project name used for authentication. This project
will be purged if --own-project is set. Defaults to
env[OS_TENANT_NAME].
--auth-url AUTH_URL Authentication URL. Defaults to env[OS_AUTH_URL].
--cleanup-project CLEANUP_PROJECT
ID or Name of project to purge. Not required if --own-
project has been set. Using --cleanup-project requires
to authenticate with admin credentials.
--own-project Delete resources of the project used to authenticate.
Useful if you don't have the admin credentials of the
platform.
--insecure Explicitly allow all OpenStack clients to perform
insecure SSL (https) requests. The server's
certificate will not be verified against any
certificate authorities. This option should be used
with caution.
The following error codes are returned when ospurge encounters
an error:
- Code 2: Project doesn't exist
- Code 3: Authentication failed (e.g. Bad username or password)
- Code 4: Resource deletion failed
- Code 5: Connection error while deleting a resource (e.g. Service not available)
- Code 6: Connection to endpoint failed (e.g. authentication url)
- Code 1: Unknown error
- Code 0: Process exited sucessfully
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 --cleanup-project option or the
--own-project option. When the command returns, any resources associated
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
Checking resources of the target project:
$ ./ospurge --dry-run --cleanup-project florent-demo
