# First deployment checklist A pragmatic list for the first production-ish Monlet stand-up. Adjust per environment. ## 1. Secrets - [ ] Generate `MONLET_AUTH_TOKEN` (`openssl rand -hex 32`) and store it in your secret manager. - [ ] Generate `MONLET_WEB_SESSION_SECRET` (`openssl rand -hex 32`) if local web login is enabled. - [ ] Generate a PostgreSQL password and store it in your secret manager. - [ ] Decide which notifier channels you want and gather their credentials (Telegram bot token + chat id, webhook URL, Alertmanager URL). ## 2. Database - [ ] Provision PostgreSQL 16+. - [ ] Create `monlet` database and role with `CREATE`/`USAGE` on the schema. - [ ] Set `MONLET_DATABASE_URL=postgresql+asyncpg://...`. - [ ] Keep database/server runtime timezone at UTC; only UI/notifier presentation should use local timezones. - [ ] Run `alembic upgrade head` from a one-shot container or the server image. - [ ] Verify `\dt` shows `agents, checks, events, incidents, notification_outbox`. ## 3. Server - [ ] Set env vars per `server/.env.example` (see also `server/README.md`). - [ ] Start container; verify `GET /api/v1/health` and `/api/v1/ready` return 200. - [ ] Verify `/metrics` exposes `monlet_server_*`. - [ ] Confirm an authenticated `GET /api/v1/agents` returns `{ items: [], next_cursor: null }`. - [ ] Confirm logs show no unredacted token/cookie material. ## 4. Agent (per host) - [ ] Install binary (see `agent/systemd/`). - [ ] Render `config.toml` from `agent/config.example.toml`; omit `agent_id` to use the OS hostname, or set explicit `agent_id` when the host name is not a stable Monlet identifier. - [ ] Start under systemd; verify the host appears as `pending` in `GET /api/v1/agents`, then accept it in the UI/API. - [ ] Run one configured check and verify a row appears in `/api/v1/checks` and an event in `/api/v1/events/query`. ## 5. Notifications - [ ] Enable at least one notifier in server env (`MONLET_NOTIFIER_*`). - [ ] Force a `critical` event from one agent and confirm an outbox row reaches `sent` (`GET /api/v1/notifiers/outbox`). - [ ] Resolve the check and confirm a `resolved` outbox row is emitted. ## 6. Web UI - [ ] Set `MONLET_API_BASE_URL`, `MONLET_API_TOKEN`, and optional `MONLET_WEB_TIME_ZONE` for the web container. - [ ] Protect the web UI with either local login (`MONLET_WEB_AUTH_USERNAME`, `MONLET_WEB_AUTH_PASSWORD`, `MONLET_WEB_SESSION_SECRET`) or a trusted reverse proxy that sets `X-Forwarded-User` plus `MONLET_WEB_TRUST_PROXY_AUTH=true`. - [ ] Rate-limit `/login` at the reverse proxy when local web login is enabled. - [ ] Set optional `MONLET_NOTIFICATION_TIME_ZONE` for human-readable notifier timestamps. - [ ] Browse `/`, `/agents`, `/checks`, `/incidents`, `/events`, `/outbox`. - [ ] Verify the web image does not log the token (`docker logs` greps clean). ## 7. Observability (optional) - [ ] Add Monlet server to your Prometheus scrape config (`deploy/prometheus/prometheus.yml`). - [ ] Import `deploy/grafana/dashboards/monlet-overview.json` for the starter dashboard. - [ ] If using Alertmanager as a notifier, point `MONLET_NOTIFIER_ALERTMANAGER_URL` at it. ## 8. Operational - [ ] Schedule database backups (`docs/ops/backup-restore.md`). - [ ] Document token rotation owner and cadence (`docs/ops/token-rotation.md`). - [ ] Add `monlet_server_open_incidents` and `monlet_server_agents{status="dead"}` to your dashboards. - [ ] Decide an `events` retention policy.
