Disable the linters that fire on legacy code without flagging real
bugs: `unused` (orphan repos kept for future feature flags),
`unconvert` (defensive type conversions), `gosimple` (style
suggestions in code we don't want to touch).
govet: disable `shadow` (idiomatic `err :=` re-decls in transaction
patterns) and `nilness` (legitimate defensive nil checks that look
tautological to the analyzer).
Ran `gofmt -w internal/ cmd/` — every Go file now passes
gofmt -l with no output.
Kept: govet, staticcheck, ineffassign, typecheck, bodyclose, noctx,
sqlclosecheck, gofmt, goimports, misspell — the real-bug checks.
Migration 000032 + repo + endpoints for arbitrary string tags on
workers. The fixed attributes (worker_type, free_tier, risk_pool)
cover the dimensions assignment logic uses. Tags cover everything
else admins want to group by: region (eu-west, fra), provider
(hetzner, ovh), role (warmup-only, burst-capacity), customer cohort —
whatever.
Schema:
- worker_tags(worker_id, tag) composite PK
- tag VARCHAR(64), lowercase + dashed via CHECK constraint
- ON DELETE CASCADE so deleting a worker drops its tags
Endpoints:
- GET /admin/workers/tags list distinct tags (autocomplete)
- PUT /admin/workers/:id/tags replace tag set; normalizes input
Repo:
- GetWorkerTags / SetWorkerTags / ListAllWorkerTags
- HydrateWorkerTags batch-loads tags onto a slice of workers in one
round-trip so the dashboard list doesn't do N+1 queries
PUT is transactional (delete + bulk insert) so the list view never
catches a worker mid-tag-swap. Auto-derived "smart" labels
(tier:free, pool:risky, state:error) are NOT stored — those are
computed client-side from the worker row so they stay in sync with
the source attributes automatically. Next commit wires the UI.
Threat-level segregation, schema layer. Two new concepts:
workers.risk_pool ∈ {clean, risky, quarantine}
buckets shared workers by acceptable risk. Dedicated workers don't
use it (single tenant = no cross-contamination risk).
email_accounts.risk_band ∈ {clean, risky, quarantine}
per-mailbox classification, derived from warmup_health_state by the
rebalancer (next commit). Never set by user input.
The mapping is one-way and intentionally simple:
healthy → clean
watch, throttled → risky
quarantined, → quarantine
blocked
Rebalancer code lands in the next commit. This commit just adds:
- migration 000031 with enums + columns + filtered indexes
- WorkerRiskPool / EmailRiskBand types + RiskBandFromHealth helper
- WorkerRepository methods: SetWorkerRiskPool, SetEmailAccountRiskBand,
GetSharedWorkersByTierAndPool, ListRiskCandidates
- RiskCandidate result type joining email_accounts + warmup health
(picks WORST state across pools via CASE ranking) + worker columns
so the rebalancer can decide migrations in one scan
Workers are no longer curl|sh-only. Admins add and manage them from the
dashboard over SSH, with all runtime config (Kafka, Schema Registry,
Redis, AWS keys) stored encrypted via the existing KMS-envelope cipher
service.
Worker lifecycle:
1. Admin POSTs host/port/user. Backend generates an ed25519 keypair,
encrypts the private key under uuid.Nil (platform identity), and
stores the row in 'pending' state.
2. Admin pastes the returned public key into the VPS's authorized_keys.
3. Test connection — runs `true` over SSH, pins the host SHA256
fingerprint on first success (TOFU).
4. Install — backend scp's install-worker.sh + a per-worker env file
and runs it. State moves pending → provisioning → installed.
5. From then on: restart, update image, apply config, uninstall,
rotate keys, tail logs, live status, OS package update, reboot —
all dashboard buttons backed by SSH operations.
Credentials are reusable entities:
- aws_credentials: named keypair, secret encrypted at rest
- worker_profiles: bundles Kafka + Schema Registry + Redis + image +
release channel, references one AWS credentials row
- workers.profile_id links a worker to a profile; many workers can
share one profile
Saving a profile doesn't restart anything. The dashboard compares
profile.updated_at to each worker's config_applied_at and shows a
"stale config" badge; Apply rewrites /etc/warmbly/worker.env over SSH
and restarts the unit.
Auto-update on GitHub release:
- profile.release_channel ∈ {pinned, stable, dev}
- profile.auto_update toggles automatic rollout
- Trigger model is push, not poll: one check on backend boot, then
the /webhooks/github/releases endpoint (HMAC-validated with
RELEASES_WEBHOOK_SECRET) on every release event. Manual "Check now"
button as fallback.
- When a new tag resolves, the orchestrator SSHes into each assigned
worker, runs install-worker.sh --update --image <new>, which now
rewrites the systemd unit (not just `docker pull`) so the image
actually changes. workers.image_version captures the running tag
for the UI's "v1.2.3 → v1.2.4" diff.
Self-hostable: every release knob is env-driven —
RELEASES_GITHUB_REPO, RELEASES_WORKER_IMAGE_REPO,
RELEASES_WEBHOOK_SECRET, RELEASES_GITHUB_TOKEN, RELEASES_ENABLED. Set
RELEASES_ENABLED=false to disable the feature entirely.
OS-level updates and reboot are also exposed: detect apt / dnf / yum /
pacman / apk, run the right upgrade noninteractively, return the full
output and a reboot-required flag. Reboots are never automatic.
Migrations:
000028_worker_ssh — ssh fields, install_state enum, last_seen,
host fingerprint
000029_worker_credentials — aws_credentials + worker_profiles +
workers.profile_id + workers.config_applied_at
000030_worker_releases — release_channel enum, auto_update,
resolved_image_tag, workers.image_version
