Lower RAM/disk for the same metric volume on an 8GB single node — VM's
own compression is the entire reason it exists as a project. Speaks
Prometheus's own query API (/api/v1/query), so nothing downstream
needed to change beyond the URL it points at: same PromQL, same
kubernetes-nodes-cadvisor-sourced container_cpu_usage_seconds_total /
container_memory_working_set_bytes toolshed's metrics work
(docs/PRODUCT-ARCHITECTURE.md step 5) already targets.
Three releases, matching the one-release-per-component convention
already used everywhere in this repo, since victoria-metrics-single has
no bundled scraper/exporter subcharts the way the Prometheus chart did:
- victoria-metrics-single: the TSDB + query engine. 3Gi/local-path,
7-day retention, resources capped at 512Mi — same trim reasoning as
the Prometheus server it replaces.
- vmagent: the scraper. Its default scrape_configs already includes
kubernetes-nodes-cadvisor and kubernetes-service-endpoints (the
chart's own comment says "COPY from Prometheus helm chart") — nothing
to override there, only remoteWrite pointed at victoria-metrics-single
and trimmed resources.
- node-exporter: pulled out of the removed Prometheus chart's bundled
subchart into its own standalone release, since victoria-metrics-single
has no equivalent. Same trim as before (32Mi/64Mi), same
prometheus.io/scrape annotation vmagent's default scrape config
already looks for.
Found and fixed while vendoring: helm-templates/victoria-metrics-single
already existed in this repo — a leftover GKE-targeted vendored copy
from the original Meesho monorepo import (commit b8575bb), with its own
templates/values.yaml for a different chart entirely. `mkdir -p` on an
already-existing directory silently did nothing, so the first vendoring
attempt left that old tree sitting alongside the new one and rendered
two ServiceAccounts/Services/StatefulSets with colliding names. Removed
outright rather than adapted, same reasoning as the ~35 charts
devops-helm-charts removed in its own prune — see this chart's own
Chart.yaml for the full note.
Verified with `helm template` against the real charts and these values
for all three releases individually, and again for the whole
generic-argo-apps-chart appSpec list (11 Applications render, including
the three new ones and nothing orphaned from the old prometheus entry).
