Topology rows deleted without a proper teardown leave Docker containers and bridge networks behind, holding IPAM pools that cause 403 "Pool overlaps" on the next deploy at the same subnet. - engine/reaper.py walks the local Docker daemon, extracts the 8-char topology prefix from every decnet_t_* resource, and force-removes containers + networks whose prefix is not in the repo. - POST /api/v1/topologies/reap-orphans (admin-only) returns a report of live/orphan prefixes and what was removed. - Resources belonging to live topologies are never touched; per-resource errors are captured without aborting the sweep.

"""POST /topologies/reap-orphans — remove Docker resources for topology
|
|
ids the DB no longer knows about.
|
|
|
|
A topology row deleted outside the teardown flow (operator error,
|
|
crashed master, direct DB edit) leaves its containers and bridge
|
|
networks behind. The orphan networks keep their IPAM pools, so the
|
|
next deploy at the same subnet hits a 403 ``Pool overlaps`` from the
|
|
Docker daemon.
|
|
|
|
This endpoint walks the local Docker daemon, computes the set of
|
|
topology prefixes still known to the repo, and force-removes every
|
|
container + network whose prefix is orphaned. Resources belonging to
|
|
live topologies are never touched.
