Grafana: real dashboards over VictoriaMetrics. Provisioned rather than
clicked through: a VictoriaMetrics datasource (type: prometheus — VM
speaks that query API, which is the whole point of it existing) is
baked into the chart's own datasource-provisioning config, so a fresh
install has it working with no manual setup. Admin credentials from
Vault via ExternalSecret (secretstores/grafana-admin-credentials.yaml
in devops-infra-argo-config), same pattern as every other admin
credential in this project — never plaintext in this repo. 1Gi
local-path PVC for dashboards/Grafana's own state (VictoriaMetrics
holds the actual metric data, not this). Dual LAN+Tailscale Ingress
hosts, same convention as everything externally reachable here.
Found and fixed while vendoring: helm-templates/grafana already held a
fully-vendored old Grafana chart (v6.58.7, appVersion 10.0.3) from the
original Meesho monorepo import (commit b8575bb) — generic production
config (fullnameOverride: grafana-infra-prd, GKE-shaped RBAC/PSP
defaults) unrelated to this homelab, same class of leftover as
victoria-metrics-single's collision two commits ago. Removed and
re-vendored fresh (10.5.15) as a thin wrapper, matching every other
official-chart component in this repo now.
vmui: VictoriaMetrics' own built-in UI (ad-hoc PromQL + graphs, no
saved dashboards — what Grafana is for) is served on the same
pod/port, so exposing it cost one ingress block on the
victoria-metrics-single values already committed. No new component,
no new RAM.
Verified with `helm template` against the real charts for both
components individually (Grafana: admin env vars correctly reference
the ExternalSecret's keys, datasource ConfigMap renders the intended
VictoriaMetrics URL, PVC/resources/ingress hosts all match; vmui:
ingress renders both hostnames pointing at the existing Service's named
http port) and again for the whole generic-argo-apps-chart appSpec
list — 12 Applications render, including grafana.
