Prometheus — deploy

Everything in this directory lands on a VPS the first time Prometheus is set up on it, plus files that get swapped out on each release.

deploy/
  prometheus-service.service        systemd unit — the Node service on :3700
  prometheus-x.conf                 angie vhost — TLS-terminated reverse proxy
  prometheus-snapshot.service       systemd unit — weekly snapshot job
  prometheus-snapshot.timer         systemd timer — Sunday 04:00 UTC
  apps-silentmode-st.conf           angie vhost — SEO mirror (apps.silentmode.st)
  make-tls-cert.sh                  (re-)generate the self-signed cert, print the pin

Register the on-chain record (workstation)

IP=$(curl -s https://ifconfig.io)       # or the VPS's public IP as you know it
TLS=<the fingerprint make-tls-cert.sh printed>

node Argus/src/register.js prometheus.x "{\"ip\":\"$IP\",\"tls\":\"$TLS\"}"
# Prompts for the chipnet keystore password (or set DEVIANT_KEYSTORE_PASSWORD).

The current record (as of 2026-10-08) is {"u":"https://silentmode.st/prometheus/"}. The register command above replaces it. Within a few minutes of the TX confirming on chipnet, Theseus and Ariadne resolve prometheus.x to the live service rather than the silentmode.st teaser.

Updates

Code: rsync Prometheus/ again, npm install --omit=dev (safe no-op if deps unchanged), systemctl restart prometheus-service.

Snapshot: nothing to do — the timer runs itself.

Cert rotation: re-run make-tls-cert.sh, grab the new fingerprint, re-register the tls record, reload angie. Theseus and Ariadne pick up the new cert as soon as the record TX confirms.

Rollback

Code: rsync the previous checkout, restart. There is no "schema down migration" discipline yet — the DB file is append-only in practice (new columns, new tables); if a rollback hits a schema change you have to decide what to do with the newer rows.

Record: node Argus/src/register.js prometheus.x '{"u":"https://silentmode.st/prometheus/"}' puts the name back to redirecting at the ICANN mirror. Takes the same few minutes as any other record change.
