Utility for cleaning up environment after Tempest run
Runtime Arguments
--init-saved-state: Before you can execute cleanup you must initialize
the saved state by running it with the --init-saved-state flag
(creating ./saved_state.json), which protects your deployment from
cleanup deleting objects you want to keep. Typically you would run
cleanup with --init-saved-state prior to a tempest run. If this is not
the case saved_state.json must be edited, removing objects you want
cleanup to delete.
--dry-run: Creates a report (dry_run.json) of the tenants that will be
cleaned up (in the "_tenants_to_clean" array), and the global objects
that will be removed (tenants, users, flavors and images). Once
cleanup is executed in normal mode, running it again with --dry-run
should yield an empty report.
**NOTE**: The _tenants_to_clean array in dry-run.json lists the
tenants that cleanup will loop through and delete child objects, not
delete the tenant itself. This may differ from the tenants array as you
can clean the tempest and alternate tempest tenants but not delete the
tenants themselves. This is actually the default behavior.
**Normal mode**: running with no arguments, will query your deployment and
build a list of objects to delete after filtering out out the objects
found in saved_state.json and based on the
--preserve-tempest-conf-objects and
--delete-tempest-conf-objects flags.
By default the tempest and alternate tempest users and tenants are not
deleted and the admin user specified in tempest.conf is never deleted.
Please run with --help to see full list of options.
