End-to-end extraction of the Instance concept. After this commit:
* internal/store/instances.go — DELETED
* internal/store/models.go — Instance struct gone, ProxyRoute moved here
* containers table is the single source of truth for project/stack/site
container state. instances table is dropped via DROP TABLE migration
(idempotent; re-runnable on every boot).
* Legacy tinyforge.project / tinyforge.stage / tinyforge.instance-id
Docker labels are no longer emitted; only tinyforge.workload.{id,kind},
tinyforge.role, and tinyforge.managed are stamped on new containers.
Backend rewrites:
- internal/deployer: executeDeploy + blueGreenDeploy + rollback +
promote use store.Container natively. New
removeContainer() replaces removeInstance().
enforceMaxInstances reads via
ListContainersByStageID.
- internal/reconciler: legacy tinyforge.instance-id dispatch removed;
upsertByWorkloadLabel now finds existing rows
by docker container ID first and falls back to
the deterministic workloadID:role key.
- internal/stale/scanner: Scan + new FindStaleContainers walk the
containers table; emit StaleContainer JSON.
- internal/stats/collector: ListContainers replaces ListAllInstances.
- internal/webhook/handler: workload-secret lookup tried first; falls back
to project / static_site secret column.
- internal/api: instances.go, stale.go, stats.go, stats_history.go,
projects.go, settings.go, docker.go, dns.go all read /
write through Container.
Docker layer:
- ManagedContainer exposes WorkloadID/Kind/Role from the canonical labels.
- ListContainers filters by tinyforge.managed=true.
- Network creation uses LabelManaged instead of LabelProject.
Frontend:
- Instance type is now a Container alias; .status → .state,
.last_alive_at → .last_seen_at.
- InstanceCard takes stageId as a prop (no longer derived from Instance).
- StaleContainer JSON shape rewritten: { container, workload_name, role,
days_stale }. StaleContainerCard + /containers/stale page updated.
- ProjectCard / homepage / SystemHealthCard filter by .state.
The migration loop now tolerates "no such table" alongside "duplicate
column" / "already exists" so obsolete ALTER TABLE entries targeting the
dropped instances table no-op cleanly on first boot.
Tests: store + deployer + reconciler + webhook + staticsite + notify all
still pass. Frontend svelte-check: zero errors.
Background worker that keeps the containers table in sync with
docker ps. Runs one boot pass and ticks every 30s.
Dispatch precedence per container:
1. tinyforge.workload.id label (canonical, new)
2. tinyforge.instance-id label (legacy project — joins via instances)
3. tinyforge.static-site label (legacy site)
4. com.docker.compose.project (stacks — joins via ComposeProjectName)
Rows whose Docker container ID is no longer present are flipped
to state='missing'. Placeholder rows (empty container_id, e.g.
a deploy mid-flight) are left alone so a tick that races a
deploy doesn't mark them as missing.
DockerLister interface lets tests substitute a fake daemon —
6 unit tests cover the dispatch matrix, missing-sweep, and
state normalization.
Wired into cmd/server/main.go between docker.New and the
existing startup chain. Boot pass populates the containers
table from any pre-refactor running containers.
