Hello!
Can please anybody tell me, if all resources which are created within a Heat stack belong to the stack in the way that all the resources are freed / deleted when the stack is deleted?
IMHO all resources which are created during the initial creation or update of a stack, even if they are ephemeral or only internal created, must be deleted when the stack is deleted by OpenStack Heat itself. Correct?
My question might see obvious, but I did not find an explicit hint in the documentation stating this.
The reason for my question: I have a Heat template which uses two images to create a server (using block_device_mapping_v2). Every time I run an 'openstack stack create' and 'openstack stack delete' cycle one ephemeral volume is left over / gets not deleted. For me this sounds like a problem in OpenStack (Heat). (It looks that this is at least similar to https://review.opendev.org/#/c/341008/ which never made it into master.)
Kind regards
Andre
