# monitoring
|
|
|
|
This file provides guidance to Claude Code when working in `05-monitoring`. See the [repo-root CLAUDE.md](../CLAUDE.md) for shared conventions, deployment order, and CI/CD.

Monitoring stack (Prometheus + Grafana) via the `kube-prometheus-stack` Helm chart. Reads `kubeconfig` from `k8s-bootstrap` and `domain` from `k8s-apps`, both via StackReference.
|
|
|
|
## Common Commands
|
|
|
|
```bash
|
|
npm install
|
|
pulumi up --yes
|
|
```
|
|
|
|
## Architecture
|
|
|
|
- Namespace `monitoring`
|
|
- `kube-prometheus-stack` Helm release (chart v86.2.0)
|
|
- Grafana: ingress at `grafana.<domain>` (`traefik`, `letsencrypt-prod`), `longhorn` PVC (2Gi)
|
|
- Prometheus: `longhorn` PVC (20Gi) via `volumeClaimTemplate`
|
|
- Alertmanager disabled
|
|
|
|
## Key Notes
|
|
|
|
- The `monitoring` namespace and the Helm release both use the Pulumi `import` resource option (`monitoring`, `monitoring/kube-prometheus-stack`) — they were adopted from pre-existing cluster resources rather than created fresh. Be careful with renames or changes that would force a replace.
|
|
|
|
## Required Pulumi config
|
|
|
|
```bash
|
|
pulumi config set --secret grafanaAdminPassword <password>
|
|
```
|
|
|
|
## CI/CD
