The shipped join flow (v2.2.0-v2.3.0) was a one-time snapshot: a spoke's
catalog never updated after joining. This adds the two pieces that were
explicitly designed but missing:
- Live replication: a spoke registers its own endpoint with the master
right after joining (POST /api/site/spokes, Bearer join-key), receiving
a pushToken. Every successful catalog write on the master now fires a
fire-and-forget resync ping (utils/site_replicate.js) at every known
spoke, concurrently -- one unreachable spoke never blocks or delays
another (wired into the existing write-gate middleware in
api_directory_admin.js). The spoke's POST /api/site/resync handler
reuses the already-tested export+import path rather than applying a
partial diff.
- Identical directories: POST /api/site/export now best-effort includes
the master's agent-signing key; a spoke adopts it via agent_keys.adopt()
on both join and every resync, so every site's sso-manager can validly
sign a command for any agent enrolled anywhere -- the accepted tradeoff
discussed for this deployment's scale (blast radius for simplicity).
New SiteSpoke model tracks registered spokes (endpoint + pushToken);
registered it in models/index.js (a real bug the e2e test below caught --
SiteSpoke.list() 500'd with "Cannot read properties of null (reading
'adapter')" until the model was added to initORM's model list).
Verified end-to-end against docker-compose.multisite-e2e.yml: mint join
key -> join with selfUrl -> write a NEW resource on master post-join ->
poll the spoke -> it shows up within a few seconds via the resync push,
no manual re-join needed. MULTISITE E2E PASS.
Unit tests: nodejs/tests/site_replicate.test.js (concurrent fan-out, one
failing spoke doesn't block another, empty-registry and list()-throws
edge cases).
Completes the multi-site join layer on top of the v2.2.0 endpoints:
- UI (Master Site modal): a fresh install (canJoin) gets a 'Join an Existing
Site' form (master URL + stj_ key); a master gets a 'Site Join Keys' manager
(mint/revoke/list, key shown once); WAN Sync Health now reflects a live probe.
- POST /api/site/ping (Bearer stj_ key, no admin session): lightweight master
reachability probe for WAN health (cheap vs /export).
- Spoke read-only: directory-write routes (resources/edges/groups/secrets/
grants/driver-action/discovered) reject with 403 pointing at the master.
- Fresh-install guard: /api/site/join refuses unless no users beyond the
bootstrap admin and no enrolled agents (siteIsFresh), and site-status exposes
canJoin so the UI only offers join on a genuinely fresh install. The
bootstrap's seeded default resources are NOT the signal (they always exist).
- The spoke stores the join key (masterJoinKey) in /config/site.json so WAN
health (and a future write-proxy) can reach the master.
- Tests: siteIsFresh cases in tests/site_join.test.js.
Server endpoints for joining a spoke to a master directory (MULTI_SITE_SPEC.md).
This pass is server-only; setup.sh wiring and the UI are the next layer.
- Site join keys (SiteJoinKey model, stj_ prefix): mint/revoke/delete/list,
hashed at rest, shown once — the same model as agent join keys.
- POST /api/site/export (master, Bearer stj_ key, no admin session): returns the
local LDAP tree (slapcat LDIF) + resource catalog + siteSlug + baseDn.
- POST /api/site/join (spoke, admin): { masterUrl, joinKey } pulls the master
export, imports resources (upsert by slug) + LDAP (ldapadd -c), and persists
the spoke role. Refused if already a spoke.
- Persisted site role: utils/site_config.js keeps isMaster/masterUrl/siteSlug in
/config/site.json (env seeds defaults); site-status/site-promote now use it.
- Unit tests (site_join, site_config) with in-memory stubs, wired into npm test.
- docs/site-join.md + docs router entry.
- Repairs the corrupted multi-site emojis (crown/bolt) in directory.ejs.
- .gitguardian.yml ignores the generic-password false positive on reading the
LDAP bind credential from runtime config (never a hardcoded secret).
