From 081499adc4c8b02e900e62808200e2a5a0e477ab Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Thu, 26 Feb 2026 16:33:27 +0000 Subject: [PATCH 1/2] feat: architect observability stack with Garage S3 backend - Deployed `kube-prometheus-stack` (Thanos) and `loki` on Capstan cluster (`cc`) in `monitoring` namespace. - Configured Loki and Thanos to use Garage S3 on Management Cluster (`mc`) as backend. - Enabled Ingress for Garage S3 on `mc` via Tailscale (`s3.moonwake.io`). - Tuned Loki to utilize RAM and batch writes (1.5MB chunks, 2h max age) to reduce S3 ops. - Configured Vault Secrets injection for S3 credentials in `monitoring` namespace. - Disabled CRD installation in `kube-prometheus-stack` to avoid conflict with `prometheus-operator-crds`.

Updated `DeterminateSystems/nix-installer-action` from v10 to v16 in all workflows (`manifest-diff.yaml`, `build-push-nixos-remote-builder.yaml`, `build-push-pulumi-cmp.yaml`) to fix "Invalid URL" error. - Fixed namespace mismatch for `observability` vaultSecrets (set to `monitoring`). - Corrected Loki datasource URL in `apps/base/observability/values.yaml` to use port 3100.
