Adds a fleet_deckies table so DB-only consumers (orchestrator, web dashboard, REST API) can see unihost / MACVLAN / IPVLAN deckies without reading the JSON state file. Mirrors DeckyShard field-for-field. Composite PK (host_uuid, name) future-proofs for a mothership that runs both a local fleet and acts as a swarm master. host_uuid defaults to the "local" sentinel — no FK to swarm_hosts because the local mothership isn't enrolled as a worker. Repo additions: upsert_fleet_decky, delete_fleet_decky, list_fleet_deckies, list_running_fleet_deckies, update_fleet_decky_state, plus list_running_deckies which unions topology + fleet + shard sources for the orchestrator. Smoke-tested round-trip against MySQL: upsert, list_running, union view (source="fleet"), delete.

"""Fleet decky table — DB mirror of ``decnet-state.json``.
|
|
|
|
The legacy unihost / MACVLAN / IPVLAN deploy path persists fleet state to a
|
|
JSON file (``/var/lib/decnet/decnet-state.json``) via
|
|
:func:`decnet.config.save_state`. That file is consumed directly by
|
|
``decnet status``/``decnet teardown``, the sniffer, and the collector — all
|
|
host-local CLI / worker code that may run on a box without the API daemon.
|
|
|
|
The FleetDecky table is a *mirror* of that JSON state inside MySQL/SQLite so
|
|
DB-only consumers (the orchestrator, the web dashboard, the REST API) can
|
|
see fleet decoys without touching the filesystem.
|
|
|
|
Both writers — CLI ``decnet deploy`` (``engine.deployer.deploy``) and the
|
|
web/API deploy path (``web.router.fleet.api_deploy_deckies``) — write to
|
|
*both* surfaces. A reconciler (``decnet.fleet.reconciler``) handles drift.
|
|
|
|
Schema mirrors :class:`decnet.web.db.models.swarm.DeckyShard` field-for-field
|
|
so the dashboard can render fleet rows with the same card shape. The PK is
|
|
composite ``(host_uuid, name)`` to future-proof for multi-host motherships
|
|
(a master that runs its own local fleet AND swarm-shards onto workers). In
|
|
unihost mode ``host_uuid`` defaults to the sentinel
|
|
:data:`LOCAL_HOST_SENTINEL`; we deliberately do NOT FK to ``swarm_hosts``
|
|
because the local mothership is not enrolled as a swarm worker.
