# Grafana datasource, declared in git rather than clicked into grafana.db.
#
# This Grafana is an empty install on purpose: every datasource and dashboard
# it has comes from this directory, which the deployer installs into
# /opt/grafana/provisioning (mounted read-only into the container). A
# UI-configured datasource would be invisible to review, lost with the data
# volume, and unknown to anyone reading the repository.
#
# The URL uses the container name on dankclaw_default — the same address Caddy
# proxies to — not the published loopback port, so the path is the same from
# inside the network as from the browser's server side.
