ospurgeis a standalone, client-side, operators tool that aims at deleting all resources, taking into account their interdependencies, in a specified OpenStack project.ospurgeensures in a quick and automated way that no resource is left behind when a project is deleted.ospurgecan 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.
At the moment it is possible to purge the following resources from a project:
- Ceilometer alarms
- floating IP addresses
- images / snapshots
- instances
- networks
- routers
- security groups
- Swift containers
- Swift objects
- volumes / snapshots
The following error codes are returned when ospurge encounters
an error:
Code 0: Process exited sucessfullyCode 1: Unknown errorCode 2: Project doesn't existCode 3: Authentication failed (e.g. bad username or password)Code 4: Resource deletion failedCode 5: Connection error while deleting a resource (e.g. service not available)Code 6: Connection to endpoint failed (e.g. wrong authentication URL)
Create a Python virtual environment (requires the virtualenvwrapper):
$ mkvirtualenv ospurgeInstall ospurge with pip:
$ pip install ospurgeAvailable 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 [--admin-role-name ADMIN_ROLE_NAME] --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].
--admin-role-name ADMIN_ROLE_NAME
Name of admin role. Defaults to 'admin'.
--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.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:
