prometheus/deploy/docker-compose.yml

# Standalone compose for prometheus.x on the Hephaestus VPS.
#
# The service attaches to Hephaestus's existing docker network
# (hephaestus_default), so Hephaestus's Caddy can route prometheus.x to
# `prometheus:3700` with no changes to Hephaestus itself other than one new
# block in its Caddyfile.
#
# One volume (`data`) holds the SQLite DB, the service's ed25519 signing
# key, uploads that passed scan, and the snapshot build output. Env lives
# in an .env file alongside this one; the ones below are the defaults and
# can be overridden.
