d8012dfb6c monitoring: add dashboard ideas doc
Survey of dashboards that could be built from existing and not-yet-enabled
metrics across the cluster's services (traefik, coredns, metallb, cert-manager,
phoenix, litellm, gitea, postgres, etc.), with per-service enable steps and
a recommended priority order.

bf1387dc3e monitoring: add Grafana dashboards + kube-state-metrics & node-exporter
Dashboards (provisioned via ConfigMaps into Grafana pod, 'K3s Cluster' folder):
- Cluster Overview: per-namespace CPU/mem/net/fs, pod counts, pod health (KSM)
- Pods & Services: per-pod CPU/mem/net/fs, throttling, pod status, restarts, PVCs
- Nodes: per-node CPU%/mem%, load average, disk usage, network (node-exporter)
- Control Plane & API Server: request rate, latency p95, 5xx, kubelet/PLEG
- Prometheus Self-Monitoring: ingestion, series, scrape duration, memory

Exporters (auto-scraped via existing kubernetes-service-endpoints job):
- kube-state-metrics: pod/deployment/PVC/replica state (kube_pod_status_phase,
  kube_pod_container_status_restarts_total, kube_persistentvolumeclaim_*)
- node-exporter (DaemonSet, hostNetwork): node_cpu_seconds_total,
  node_memory_*, node_filesystem_*, node_load*, node_network_*

b43874bdcd Expose minecraft server over TCP via MetalLB
Minecraft Java Edition uses raw TCP on port 25565, not HTTP. The previous
ClusterIP Service + HTTP Ingress (Traefik 80/443) could not carry TCP 25565
traffic, so minecraft.rogi.casa:25565 was unreachable.

- Change Service to LoadBalancer with fixed IP 10.88.20.103 (dmz-pool),
  matching the pihole-dns pattern, so port 25565 is exposed directly.
- Remove the dead HTTP ingress (it routed HTTP to a TCP game port).

e77e170421 fix(homeassistant): trust k3s pod/service CIDRs as X-Forwarded-For proxies
HA runs with hostNetwork on roger-nucbox-evo-x2 while Traefik runs on the
raspberrypi node, so requests arrive at HA from 10.88.20.11. The previous
trusted_proxies entry (10.88.88.0/24) did not include this address, causing
HA to reject X-Forwarded-For and return 400 on every ingress request.

# Dashboard Ideas
This file collects ideas for additional Grafana dashboards to build for the
`rogi.casa` k3s cluster. Each idea notes the **data source** (metrics already
available vs. metrics that need to be enabled) and a rough panel layout.
To actually add a dashboard, create a `grafana-dashboard-<name>.yaml` ConfigMap
in this folder, mount it in `grafana-deployment.yaml` (add a volume +
volumeMount under `/var/lib/grafana/dashboards/<name>`), commit and push.
---
## Already-scraped services (ready to dashboard now)
These exporters/services are **already being scraped by Prometheus** — dashboards
can be built immediately with no infra changes.
### 1. Traefik (Ingress) — `traefik_*`
Traefik is scraped via the `kubernetes-pods` job (pod annotation on
`traefik-9bcdbbd9-x8zq4` in `kube-system`). It exposes request counters, entry
point latency, TLS handshakes, config reloads.
**Panels:**
- Requests/sec by entrypoint (web / websecure / traefik) — `rate(traefik_entrypoint_requests_total[5m])`
- Request latency p50/p95/p99 — `histogram_quantile(0.95, sum(rate(traefik_entrypoint_request_duration_seconds_bucket[5m])) by (le, entrypoint))`
- HTTP status code distribution (2xx/3xx/4xx/5xx) — `rate(traefik_entrypoint_requests_total{code=~"2xx|3xx|4xx|5xx"}[5m])`
- TLS handshakes/sec — `rate(traefik_entrypoint_requests_tls_total[5m])`
- Config reloads + last reload success — `traefik_config_reloads_total`, `traefik_config_last_reload_success`
- Top routes/services by request volume — `topk(10, sum by (service) (rate(traefik_service_requests_total[5m])))`
- Bytes transferred in/out — `rate(traefik_entrypoint_requests_bytes_total[5m])`
**Why useful:** This is your front door. Knowing which routes get hit most,
latency per ingress, and 5xx spikes is the single most valuable app-level
dashboard in the cluster.
---
### 2. CoreDNS (cluster DNS) — `coredns_*`
Scraped via `kube-dns` Service annotation. Exposes query rate, cache hits,
error types, response duration.
**Panels:**
- DNS queries/sec by zone / type — `rate(coredns_dns_requests_total[5m])`
- Cache hit ratio — `rate(coredns_cache_hits_total[5m]) / rate(coredns_cache_requests_total[5m])`
- DNS query latency p95 — `histogram_quantile(0.95, sum(rate(coredns_dns_request_duration_seconds_bucket[5m])) by (le))`
- Queries by response code (NOERROR / NXDOMAIN / SERVFAIL) — `rate(coredns_dns_responses_total[5m])`
- Cache size — `coredns_cache_entries`
- Forward requests/sec (upstream DNS) — `rate(coredns_forward_requests_total[5m])`
**Why useful:** DNS issues cause cascading failures (ImagePullBackOff, cert
challenges, etc.). A spike in NXDOMAIN/SERVFAIL is an early warning.
---
### 3. MetalLB (LoadBalancer) — `metallb_*`
Scraped via pod annotation on `speaker-*` and `controller` in `metallb-system`.
Exposes IP allocation usage, BGP/session state.
**Panels:**
- IP addresses in use vs. total — `metallb_allocator_addresses_in_use_total` / `metallb_allocator_addresses_total`
- IP pool utilization % (gauge) — `metallb_allocator_addresses_in_use_total / metallb_allocator_addresses_total * 100`
- BGP session up per speaker — `metallb_bgp_session_up`
- Config loaded / stale status — `metallb_k8s_client_config_loaded_bool`, `metallb_k8s_client_config_stale_bool`
- Announcements per speaker — `rate(metallb_bgp_announcements_total[5m])`
**Why useful:** If MetalLB runs out of IPs, new LoadBalancer services will
hang in `<pending>`. Knowing pool utilization lets you act before that happens.
---
### 4. cert-manager (TLS certificates) — `certmanager_*`
Scraped via pod annotations on cert-manager pods. Exposes certificate
expiration, renewal, ready status, ACME challenges.
**Panels:**
- Certificate expiration (days remaining, sorted) — table of `(certmanager_certificate_not_after_timestamp_seconds - time()) / 86400`
- Certificates not Ready — `certmanager_certificate_ready_status{condition="Ready",status!="True"}`
- Upcoming renewals (next 14 days) — `certmanager_certificate_renewal_timestamp_seconds`
- ACME challenge status — `certmanager_certificate_challenge_status`
- Failed renewals counter — `rate(certmanager_certificate_renewal_total{condition="Failed"}[1h])`
**Why useful:** A cert about to expire (or silently failing to renew) is the
kind of thing that takes down `*.rogi.casa` HTTPS with no warning. This is a
must-have alert/dashboard.
---
### 5. Phoenix (trace store) — `phoenix_*`
Already scraped via the `phoenix` Service annotation. Exposes bulk loader
ingestion rates, span insertion times, retention sweeper, exceptions.
**Panels:**
- Span ingestion rate — `rate(phoenix_bulk_loader_span_insertion_time_seconds_count[5m])`
- Span insertion latency p95 — `histogram_quantile(0.95, sum(rate(phoenix_bulk_loader_span_insertion_time_seconds_bucket[5m])) by (le))`
- Span exceptions/sec — `rate(phoenix_bulk_loader_span_exceptions_total[5m])`
- Retention sweeper last run — `phoenix_retention_sweeper_last_run_seconds`
- Last activity timestamp — `phoenix_bulk_loader_last_activity_timestamp_seconds`
**Why useful:** Phoenix is your observability backend's own backend. Tracking
ingestion health tells you whether traces are landing.
---
## Infrastructure dashboards (compose from existing metrics)
### 6. Storage & PVC Health (KSM + kubelet + node-exporter)
Cross-source dashboard combining `kube_persistentvolumeclaim_*` (KSM),
`kubelet_volume_stats_*` (kubelet), and `node_filesystem_*` (node-exporter).
**Panels:**
- PVC usage % per claim — `kubelet_volume_stats_used_bytes / kubelet_volume_stats_capacity_bytes * 100`
- PVC requested vs. capacity — `kube_persistentvolumeclaim_resource_requests_storage_bytes` vs actual
- Node disk usage % (all mounts) — `(1 - node_filesystem_avail / node_filesystem_size) * 100`
- Inode usage % per mount — `(1 - node_filesystem_files_free / node_filesystem_files) * 100`
- Volume binding status (Bound/Pending) — `kube_persistentvolumeclaim_status_phase`
- Top 10 PVCs by usage (table)
**Why useful:** The `local-path` provisioner fills up node disks. Catching a
PVC at 95% before it errors is a lifesaver.
---
### 7. Workload Health (KSM)
Uses kube-state-metrics to show deployment/StatefulSet/CronJob health cluster-wide.
**Panels:**
- Deployments with unavailable replicas — `kube_deployment_status_replicas_available < kube_deployment_status_replicas`
- Pods not in Running phase by namespace — `kube_pod_status_phase{phase!="Running"}`
- Container restarts (last 1h) — `increase(kube_pod_container_status_restarts_total[1h])`
- Pods stuck in CrashLoopBackOff / ImagePullBackOff — `kube_pod_container_status_waiting_reason{reason=~"CrashLoopBackOff|ImagePullBackOff"}`
- Job failures — `kube_job_failed`
- CronJob schedule heatmap — `kube_cronjob_status_active`
- HPA status (if any autoscaled) — `kube_horizontalpodautoscaler_status_current_replicas` vs desired
**Why useful:** This is the "is anything broken" board. Notice you already have
some pods in `ImagePullBackOff` (myorg-assistant) — this dashboard surfaces that.
---
### 8. etcd / Control Plane Health (if exposed)
k3s embeds etcd (or sqlite on single-node). etcd metrics require exposing
the etcd `/metrics` endpoint (typically `--listen-metrics-urls` on the control
plane node). **Requires config change to enable.**
**Panels:**
- Leader changes — `etcd_server_leader_changes_seen_total`
- Proposal commits/sec — `rate(etcd_server_proposals_committed_total[5m])`
- Proposal failures/sec — `rate(etcd_server_proposals_failed_total[5m])`
- DB size — `etcd_mvcc_db_total_size_in_bytes`
- RPC latency p99 — `histogram_quantile(0.99, sum(rate(etcd_grpc Unary grpc latency bucket[5m])) by (le))`
- Active watchers — `etcd_debugging_mvcc_watcher_total`
**Why useful:** etcd is the brain of the cluster. Slow commits or a flipping
leader indicates control-plane trouble.
---
## App-service dashboards (require enabling metrics first)
Most of your apps don't expose `/metrics` yet. Below is the per-service setup
plus the dashboard idea once metrics are on. To enable scraping for any of
these, annotate the Service with:
```yaml
metadata:
annotations:
prometheus.io/scrape: "true"
prometheus.io/port: "<port>"
```
The existing `kubernetes-service-endpoints` scrape job will pick them up
automatically — **no Prometheus config edit needed**.
### 9. LiteLLM (LLM gateway) — needs enabling
LiteLLM exposes Prometheus metrics on its API port (`/metrics`). Annotate the
`litellm` Service.
**Panels:**
- Requests/sec by model — `rate(litellm_requests_total[5m])` by `model`
- Token usage (prompt/completion/total) — `rate(litellm_total_tokens_total[5m])`
- Spend by model — `litellm_spend_total` (if cost tracking enabled)
- Latency p95 per model — `histogram_quantile(0.95, ...)`
- Error rate by model — `rate(litellm_requests_total{status=~"5.."}[5m])`
- Rate-limit / quota hits
**Why useful:** LiteLLM is the gateway for all your AI apps (open-webui,
myorg-assistant, etc.). Token spend + per-model latency is the single best
cost/quality lever in the cluster.
---
### 10. Gitea (git + CI) — needs enabling
Gitea exposes metrics at `/metrics` when `ENABLE_METRICS=true` in `app.ini`.
Annotate `gitea-http` Service (port 3000 inside, 80 via svc).
**Panels:**
- Git push/clone/fetch rate — `gitea_actions_total` by `action`
- Active users / repos / orgs — `gitea_users_total`, `gitea_repos_total`
- Issues / PRs open — `gitea_issues_total`, `gitea_pulls_total`
- HTTP request rate + latency
- Gitea Actions runner job duration — if runner metrics exposed
**Why useful:** Gitea hosts the cluster's own GitOps repo + CI. Tracking push
rate and runner throughput catches CI storms.
---
### 11. Home Assistant — needs enabling
HA exposes Prometheus metrics via the `prometheus` integration (add to
`configuration.yaml`). Then annotate the Service.
**Panels:**
- Active entities / sensors by domain
- State change events/sec — `homeassistant_entity_states_total`
- Automation triggers/sec — `homeassistant_automation_triggered_total`
- Integrations loaded + errors
- Database size / recorder queue depth
- Zigbee/Z-Wave mesh health (if exposed)
**Why useful:** HA is a home-critical service. Event/sec spikes often indicate
sensor flapping or runaway automations.
---
### 12. Jellyfin — limited
Jellyfin doesn't ship first-class Prometheus metrics, but you can scrape it
via a sidecar (`jellyfin-prometheus-exporter`) or build a blackbox-style
dashboard on the `/health` endpoint.
**Panels:**
- Active streams — from exporter
- Transcode sessions + hw accel usage
- Library size by media type
- Playback errors
---
### 13. Pi-hole — needs enabling
Pi-hole exposes metrics on its FTL web API; the `pihole-exporter` sidecar
converts them to Prometheus format. Add as a sidecar container + annotate.
**Panels:**
- DNS queries/sec (total, blocked, cached, forwarded)
- Block list size
- Top blocked domains
- Top permitted domains
- Clients by query volume
- Cache hit ratio
**Why useful:** Pi-hole is your network-wide adblock. Block rate + cache ratio
are the headline metrics, and query spikes reveal misbehaving clients.
---
### 14. PostgreSQL (litellm + phoenix + n8n) — needs enabling
You have two Postgres instances (`postgres` in `litellm` and `phoenix`).
Add `prometheus-postgres-exporter` as a sidecar or Deployment per DB.
**Panels (per DB):**
- Connections (active / idle / max) — `pg_stat_activity_count`
- Transactions/sec — `rate(pg_stat_database_xact_commit[5m])`
- Cache hit ratio — `pg_stat_database_blks_hit / (blks_hit + blks_read)`
- Table + index bloat
- Replication lag (if replicas)
- Slow queries (if `pg_stat_statements` enabled)
- DB size growth — `pg_database_size_bytes`
**Why useful:** DB connection exhaustion and cache ratio collapse are the two
most common causes of slow app performance.
---
### 15. Minecraft — limited
The Minecraft server exposes metrics via RCON + an exporter
(`minecraft-exporter`). Add as sidecar using the existing `RCON_PASSWORD`.
**Panels:**
- Players online — `minecraft_players_online`
- TPS (ticks per second) — `minecraft_tps` (server health)
- Entities loaded — `minecraft_entities_total`
- Chunk count — `minecraft_chunks_loaded`
- Memory used by JVM
**Why useful:** TPS < 20 means lag. Player count vs. server load is the only
real signal a Minecraft server needs.
---
### 16. qBittorrent — limited
No native metrics. Options: a `qbittorrent-exporter` sidecar (uses the WebUI
API), or a blackbox probe on the WebUI.
**Panels:**
- Download/upload speed
- Active torrents
- Torrent count by state (downloading/seeding/paused)
- Disk usage in download dir
---
## Cluster meta dashboards
### 17. Network Topology / Service Map
Composite view: for each namespace, list services, their pods, scrape status,
and request volume (from Traefik logs + cAdvisor network). A "what talks to
what" overview.
**Panels:**
- Service pod container resource table
- Cross-namespace network flows (if network policy logging enabled)
- Scrape health matrix (every target up/down)
- Ingress route backend service map
---
### 18. Backup / Snapshot Status
If you take Velero snapshots or local-path snapshots, build a dashboard on
`velero_*` or CRD status. **Requires Velero.**
**Panels:**
- Last successful backup per namespace
- Failed backups
- Backup size growth
- Restore test status
---
### 19. Cost / Capacity Planning
Composite: per-namespace CPU/memory requests vs. actual usage, projected
growth, node saturation forecast.
**Panels:**
- Requests vs. limits vs. actual (per namespace) KSM + cAdvisor
- Node capacity vs. allocatable
- PVC growth trend + 30-day forecast
- "What if I removed node X" simulation (capacity headroom)
**Why useful:** Tells you when you'll need another node before you hit the wall.
---
## Recommended priority order
If you only build a few, do them in this order (highest value-to-effort first):
1. **Traefik Ingress** (#1) already scraped, your front door
2. **Storage & PVC Health** (#6) local-path fills disks; high blast radius
3. **Workload Health** (#7) surfaces CrashLoopBackOff / ImagePullBackOff
4. **cert-manager** (#4) prevents silent cert expiry outages
5. **CoreDNS** (#2) early warning for DNS cascades
6. **LiteLLM** (#9) needs `prometheus.io/scrape` annotation only; big insights
7. **MetalLB** (#3) small but catches LoadBalancer IP exhaustion
Items 819 are nice-to-have or require additional exporters/config.

# Platform Engineer Agent — Deployment Plan
An autonomous **Hermes Agent** that runs inside the k3s cluster, watches its
health on a schedule, tries to fix simple problems, and notifies me (via
Discord) when something needs my attention or a fix failed.
Docs: https://hermes-agent.nousresearch.com/docs/user-guide/docker
---
## 1. Goal & operating model
- **One Hermes container** in a new namespace `platform-engineer`, scheduled on
the powerful amd64 node (`roger-nucbox-evo-x2`, 24 GiB RAM).
- Hermes runs in **gateway mode** under s6 supervision (`command: gateway run`),
so the built-in **cron scheduler** is active and survives restarts.
- The agent talks to the cluster with `kubectl` from *inside* the container
(terminal backend = `local`). We give the pod a **ServiceAccount + ClusterRole**
scoped to read-mostly + restart/scale/delete-pod permissions.
- LLM calls are routed through the in-cluster **LiteLLM** proxy
(`litellm.rogi.casa`) — no external API keys needed in the cluster.
- Notifications go to **Discord** (reuse the pattern from `myorg-assistant`).
- A set of **cron jobs** (Hermes-native, not Kubernetes CronJobs) make the agent
run periodic checks. Watchdog checks use `[SILENT]` so it only pings me when
something is wrong.
Why Hermes-native cron (not k8s CronJobs):
- Hermes cron ticks inside the gateway, runs in an isolated agent session,
supports `[SILENT]` suppression, `deliver="discord"`, `workdir`, and
`context_from` chaining — far less plumbing than spawning a fresh pod per run.
- Cron jobs live in `~/.hermes/cron/jobs.json` on the PVC, so they survive pod
restarts and can be edited live via `hermes cron edit` without redeploying.
---
## 2. Files to create (this directory)
```
platform-engineer/
├── namespace.yaml # namespace platform-engineer
├── rbac.yaml # ServiceAccount + ClusterRole (+binding)
├── configmap.yaml # hermes config.yaml + SOUL.md + cron seed script
├── secret.yaml # DISCORD bot token, LITELLM_API_KEY, kubeconfig-less SA token
├── pvc.yaml # persistent /opt/data (HERMES_HOME)
├── dockerfile # derived image: hermes-agent + kubectl + helm
├── deployment.yaml # Deployment, schedules on amd64, mounts kube SA token
├── ingress.yaml # hermes.rogi.casa → dashboard (optional)
└── README.md # this file
```
Then add a line to `argocd/gen-apps.sh` `APPS=(...)`:
```
"platform-engineer|platform-engineer|platform-engineer|true|true"
```
and re-run `./argocd/gen-apps.sh` to generate `argocd/apps/platform-engineer.yaml`
so ArgoCD reconciles it like every other app in the repo.
---
## 3. RBAC — least privilege
ServiceAccount `platform-engineer` in ns `platform-engineer`, bound to a
**ClusterRole** scoped to *platform engineer* actions:
**Read (get/list/watch):** nodes, pods, services, deployments, statefulsets,
daemonsets, replicasets, jobs, cronjobs, events, configmaps, secrets, PVCs,
ingresses, namespaces.
**Act (patch/update on a allowlist):**
- `pods``delete` (force-restart a stuck pod), `patch` (`/evict`, annotations)
- `deployments`, `statefulsets`, `daemonsets`, `replicasets``patch` (restart
via `kubectl rollout restart` / scale), `update`
- `jobs`, `cronjobs``delete`, `patch`
- `pods/exec` (subresource) → `create` (only if we want the agent to `kubectl
exec` into pods for log-style debugging — optional; keep off initially)
- `events` → `get/list/watch` only
**No cluster-scoped writes** (no creating namespaces, no node taints, no RBAC
edits, no CRDs). The agent can *propose* those and tell me; it cannot do them
itself. All mutating calls are auditable via Kubernetes audit logs and
`kubectl auth can-i --as=system:serviceaccount:platform-engineer:platform-engineer`.
The pod uses the k3s in-cluster ServiceAccount token (`/var/run/secrets/...
/serviceaccount/token`) + the `KUBERNETES_SERVICE_HOST/PORT` env vars k3s already
injects — **no kubeconfig file, no long-lived token on disk**.
---
## 4. Image — thin derived Dockerfile
```dockerfile
FROM nousresearch/hermes-agent:latest
USER root
RUN apt-get update \
&& apt-get install -y --no-install-recommends curl gnupg \
&& curl -fsSL https://pkgs.k8s.io/core:/stable:/v1.35/deb/Release.key \
| gpg --dearmor -o /usr/share/keyrings/kubernetes-apt-keyring.gpg \

| tar -xz -C /usr/local/bin --strip-components=1 linux-amd64/helm \
&& rm -rf /var/lib/apt/lists/*
USER hermes
```
> Note: the cluster is mixed arch (arm64/amd64/arm). The agent pod is pinned to
> the amd64 node, so `linux-amd64` helm + `kubectl` packages are fine. If you
> later want it portable, switch to a multi-arch build with
> `TARGETARCH` and install matching helm arch.
Build & push to your Gitea registry (`git.rogi.casa/roger/...`) — same
`imagePullSecrets: gitea-registry` pattern as `gym-tracker`. Tag with the
hermes version + a short git sha.

## 5. Hermes configuration (mounted via ConfigMap → /opt/data/config.yaml)
```yaml
# config.yaml (seeded into the PVC on first boot)
model:
provider: openai-api
default: claude-4.5-haiku
base_url: "https://litellm.rogi.casa/v1"
api_mode: chat_completions
# Use a cheap, fast model for auxiliary tasks (titling, compression)
auxiliary:
compression:
provider: openai-api
model: gemini-3-flash
title_generation:
provider: openai-api
model: gemini-3-flash
terminal:
backend: local
cwd: /workspace # a working dir for any kubectl output / scratch
timeout: 180
home_mode: profile # isolate tool credentials under HERMES_HOME/home
# Unattended gateway → circuit-breaker on tool-call loops
tool_loop_guardrails:
hard_stop_enabled: true
hard_stop_after:
exact_failure: 5
idempotent_no_progress: 5
sessions:
auto_prune: true
retention_days: 90
cron:
wrap_response: false # cleaner Discord messages
memory:
memory_enabled: true
user_profile_enabled: true
```
`.env` (from Secret, mounted to `/opt/data/.env`):
```
OPENAI_API_KEY=<LITELLM_API_KEY value, i.e. sk-...>
OPENAI_BASE_URL=https://litellm.rogi.casa/v1
DISCORD_BOT_TOKEN=<new dedicated bot token>
DISCORD_HOME_CHANNEL=<your user/channel id for alerts>
# Dashboard auth (homelab, trusted LAN behind ingress)
HERMES_DASHBOARD_BASIC_AUTH_USERNAME=roger
HERMES_DASHBOARD_BASIC_AUTH_PASSWORD=<strong password>
```
> Why `OPENAI_API_KEY` + `OPENAI_BASE_URL`: the `openai-api` provider honours
> `OPENAI_BASE_URL`, so this is the simplest way to point Hermes at the
> in-cluster LiteLLM. `claude-4.5-haiku` / `gemini-3-flash` are the model names
> already exposed by your `litellm/litellm.yaml` ConfigMap.
`SOUL.md` (personality + guardrails) — see `configmap.yaml`. Key points:
- Identity: "Platform Engineer for the rogi.casa k3s cluster."
- Knows the cluster layout (3 nodes, ArgoCD GitOps, Traefik+cert-manager,
LiteLLM, services list).
- Operating rules: read-first; only act on the allowlisted verbs; never edit
RBAC / taints / namespaces / CRDs; when in doubt, notify instead of acting;
always cite the resource and the command used.
- How to reach me: `deliver="discord"`.
---
## 6. Deployment
- `replicas: 1` (Hermes data dir is single-writer — never scale >1).
- `nodeSelector: kubernetes.io/arch: amd64` + preferred `hardware: high-memory`
affinity → lands on the NUC.
- `resources`: requests 512Mi/250m, limits 2Gi/1 core (Hermes recommends
24 GiB; 1 GiB is fine without browser tools, which we keep off).
- Volume: PVC mounted at `/opt/data` (HERMES_HOME), RWX not needed (single pod).
- Ports: 8642 (gateway API, internal only) and 9119 (dashboard) → exposed via
Ingress `hermes.rogi.casa` with TLS + basic-auth (already enforced by the
`HERMES_DASHBOARD_BASIC_AUTH_*` env vars).
- `imagePullSecrets: gitea-registry`.
- env from Secret; `HERMES_DASHBOARD=1`.
- Init: on first boot the s6 `01-hermes-setup` hook seeds config/SOUL/.env from
the ConfigMap if the volume is empty. We mount the ConfigMap as a readonly
projection at `/opt/seed/` and run a tiny initContainer to copy it into
`/opt/data` only when `/opt/data/config.yaml` doesn't exist (so ArgoCD
self-heal never fights the agent's live-edited config).
---
## 7. Cron jobs to seed (Hermes-native)
These are written by an init script (one-shot Job `hermes-cron-seed`) that runs
`hermes cron create ...` against the gateway on first install, and is idempotent
(it checks existing job names). All deliver to Discord. Examples:
| Name | Schedule | Prompt (abbreviated) |
|------|----------|------------------------|
| `cluster-health-check` | `every 15m` | Run `kubectl get nodes,pods -A --field-selector=status.phase!=Running,status.phase!=Succeeded` and `kubectl get events -A --field-selector type=Warning --since=20m`. If everything healthy, reply with only `[SILENT]`. Otherwise summarize failures and root-cause briefly. |
| `pod-restart-loop` | `every 10m` | Find pods in `CrashLoopBackOff`/`ImagePullBackOff` across all namespaces. For `CrashLoopBackOff`, fetch logs and if a clear transient cause (OOM, config parse, missing secret) is visible, attempt `kubectl rollout restart <deploy>`; otherwise notify me with the log excerpt. Reply `[SILENT]` if none found. |
| `pvc-pressure` | `every 30m` | `kubectl get pv` + node disk via `kubectl top nodes`. Alert if any PVC `Bound` to a near-full volume or node disk >85%. `[SILENT]` otherwise. |
| `argocd-sync-health` | `every 1h` | `kubectl get applications -n argocd -o wide` (or `argocd app sync --dry-run` if CLI present). Report any `OutOfSync`/`Degraded` app. `[SILENT]` if all `Synced`+`Healthy`. |
| `cert-expiry` | `every 1d at 09:00` | List cert-manager `Certificate` resources with expiry < 21 days. Notify only if any. `[SILENT]` otherwise. |
| `node-resource-drift` | `every 30m` | `kubectl top nodes`. Alert if any node CPU>90% or mem>90% sustained, or any node `NotReady`. `[SILENT]` otherwise. |
| `daily-cluster-report` | `0 8 * * *` | Summarize: node count/status, top 5 pods by CPU/mem, # pods not Running, # ArgoCD apps OutOfSync, cert warnings. Always deliver (no `[SILENT]`). |
Design rules baked into SOUL.md:
- **Read-only checks** run frequently (1030m) and stay silent unless wrong.
- **Mutating actions** are restricted to safe idempotent ones (rollout restart,
delete stuck pod so controller recreates). Anything riskier → notify me with
a proposed command and wait for me to run it (I can reply in Discord to the
continuable thread).
- Cron sessions are isolated and **cannot create new cron jobs** (Hermes
disables that inside cron runs) → no runaway loops.
---
## 8. Safety & guardrails
1. **RBAC is the real boundary.** Even if the agent goes rogue, the SA can't
touch other namespaces' secrets beyond read, can't change RBAC, can't taint
nodes, can't create namespaces.
2. **`tool_loop_guardrails.hard_stop_enabled: true`** — circuit-breaks a stuck
gateway (recommended in the Docker doc for unattended deployments).
3. **`skills.write_approval: false` but `memory.write_approval: true`** (so the
agent can build skills/memories but I review memory writes lazily — flip
this if it gets noisy).
4. **No `pods/exec` subresource** initially (keep the agent from shelling into
workloads). Enable later only if you want log-grep-style debugging.
5. **Dashboard behind ingress TLS + basic auth** (the June-2026 hardening makes
auth mandatory on non-loopback binds; we satisfy it with the bundled
basic-auth provider).
6. **Single replica / single-writer PVC** — the Docker doc is explicit that two
gateways on the same `/opt/data` corrupt session/memory stores. Use a
`podAntiAffinity` so an accidental scale-up doesn't co-run.
7. **ArgoCD interaction:** keep `syncPolicy.automated.prune+selfHeal` but
exclude the live-edited hermes state. Practically: Argo owns the *manifests*
(deployment, configmap, secret, pvc), while `/opt/data` (config.yaml,
cron/jobs.json, SOUL.md edits made via the dashboard) is runtime state on the
PVC and is *not* reconciled by Argo. The ConfigMap only *seeds* it on first
boot. Document this clearly in the README so future-you doesn't expect Argo
to reset the agent's personality.
---
## 9. Rollout plan
1. Build & push the derived image to `git.rogi.casa/roger/hermes-agent` (tag
`v1.35-<sha>`).
2. Create the namespace + RBAC + Secret + ConfigMap + PVC:
`kubectl apply -f platform-engineer/`.
3. Create the `platform-engineer` Discord bot, invite it, put its token + your
channel id in `secret.yaml` (base64).
4. Apply the Deployment; wait for the pod to go Running.
5. `kubectl exec` in and run the one-shot cron seed:
`hermes cron create ...` (or apply the `cron-seed` Job).
6. Trigger the first `cluster-health-check` manually: `hermes cron run cluster-health-check`.
7. Add the app to `argocd/gen-apps.sh`, regenerate, commit, push.
---
## 10. Decisions (locked in)
1. **Notifications:** dedicated `platform-engineer` Discord bot → its own token
in `secret.yaml` (`DISCORD_BOT_TOKEN`, `DISCORD_HOME_CHANNEL`).
2. **Dashboard:** public at `hermes.rogi.casa` (Traefik TLS + cert-manager + the
bundled Hermes basic-auth provider). Reach the dashboard on port 9119; the
gateway API on 8642 is ClusterIP-only.
3. **Image:** derived image pushed to `git.rogi.casa/roger/hermes-agent`, pulled
via the existing `gitea-registry` imagePullSecret (must also exist in the
`platform-engineer` ns — see deploy steps).
4. **Model:** `qwen-3.6:27b` via the in-cluster Ollama box (`10.88.20.12:11434`),
exposed through LiteLLM as `qwen-3.6:27b`. Added to `litellm/litellm.yaml`.
Hermes reaches LiteLLM at `https://litellm.rogi.casa/v1` (never Ollama directly).
5. **pods/exec:** granted (`pods/exec` → `create` in the ClusterRole) so the
agent can `kubectl exec`/`kubectl logs` for debugging.
---
## 11. Deployment checklist (do in this order)
1. **Add the Ollama model to LiteLLM** (already done in `litellm/litellm.yaml`):
the `qwen-3.6:27b` entry points at `http://10.88.20.12:11434`. Make sure
`qwen3.6:27b` is actually pulled on that Ollama host
(`ollama pull qwen3.6:27b`). Apply: `kubectl apply -f litellm/` and restart
the LiteLLM pod so the new config takes effect.
2. **Create the `gitea-registry` secret in the new namespace** (ArgoCD won't
create it — it's not in the repo):
```
kubectl create namespace platform-engineer
kubectl create secret docker-registry gitea-registry \
--docker-server=git.rogi.casa \
--docker-username=<your-gitea-user> \
--docker-password=<gitea-access-token> \
--docker-email=<your-email> \
-n platform-engineer
```
3. **Build & push the image:** `./platform-engineer/build-and-push.sh`
(after `docker login git.rogi.casa`).
4. **Create the dedicated Discord bot**, invite it to your server, and put the
token + your channel id (base64) into `platform-engineer/secret.yaml`. Also
set the LiteLLM master key as `OPENAI_API_KEY` and a strong dashboard
password + a 32-byte session secret.
5. **Commit & push** the whole change. ArgoCD will create the namespace
resources, deploy the pod, and bring up the ingress at `hermes.rogi.casa`.
6. **Seed the cron jobs:**
`kubectl apply -f platform-engineer/cron-seed.yaml` (one-shot Job) — it waits
for the hermes pod, then runs `hermes cron create ...` for each watchdog.
Re-run it any time you want to re-seed after a wipe.
7. **Smoke test:** trigger the first health check manually —
`kubectl exec -n platform-engineer deploy/hermes -- hermes cron run cluster-health-check` —
and confirm the message lands in Discord.
8. **ArgoCD:** the `Application` (`argocd/apps/platform-engineer.yaml`) is
already generated. After commit, Argo will reconcile it like every other app.
## 12. What ArgoCD owns vs. what is runtime state
- **ArgoCD owns** (in git): namespace, RBAC, Secret, ConfigMap (seed), PVC,
Deployment, Service, Ingress, cron-seed Job.
- **Runtime state (on the PVC, NOT reconciled):** `config.yaml`, `SOUL.md`,
`.env`, `cron/jobs.json`, `sessions/`, `memories/`, `skills/`. The ConfigMap
only *seeds* these on first boot; after that, edits you make via the
dashboard or `hermes cron edit` persist on the PVC and Argo will not revert
them. If you ever want a hard reset, delete the PVC and re-apply.

# Platform Engineer — rogi.casa k3s cluster
You are the autonomous Platform Engineer for the `rogi.casa` K3s cluster.
You run *inside* the cluster (namespace `platform-engineer`) and your job is
to keep it healthy, fix small problems before they grow, and notify your
owner (Roger) on Discord when something needs a human.
## The cluster you look after
- **Nodes:**
- `raspberrypi` — control-plane, arm64 (4 GiB)
- `rpi2` — worker, arm, very low memory (~512 MiB)
- `roger-nucbox-evo-x2` — worker, amd64, 24 GiB (you run here)
- **GitOps:** ArgoCD owns every app from `https://git.rogi.casa/roger/k3s-cluster.git`.
Each app lives in its own folder; manifests are reconciled with prune + selfHeal.
- **Ingress:** Traefik; TLS via cert-manager + `letsencrypt-prod` Cloudflare Origin issuer.
- **LLM gateway:** LiteLLM at `https://litellm.rogi.casa/v1` — this is *your* model provider (you reach it through the Traefik ingress, never Ollama directly).
- **Services:** glance, pihole, litellm, gitea, home-assistant, jellyfin, n8n,
openwebui, phoenix, vaultwarden, qbittorrent, minecraft, monitoring
(prometheus + grafana), fava, myorg-assistant, gym-tracker, nas-proxy.
- **Your own RBAC** lets you read almost everything and mutate only an
allowlist (restart deployments/statefulsets/daemonsets, delete a stuck pod,
delete/patch jobs/cronjobs, `kubectl exec`). You CANNOT edit RBAC, taint
nodes, create/delete namespaces, or touch CRDs — if you think you need to,
propose the command to Roger and stop.
## Operating rules
1. **Read first, act second.** Before changing anything, gather the evidence:
`kubectl describe`, `kubectl logs`, `kubectl get events --since=...`,
`kubectl top`. Cite the exact resource (ns/name) and the exact command in
every report.
2. **Only safe, idempotent remediations.** Allowed actions:
- `kubectl rollout restart deployment/<name> -n <ns>` (and statefulset/daemonset)
- delete a single stuck `CrashLoopBackOff`/`ImagePullBackOff` pod so its
controller recreates it
- `kubectl delete job/<name>` / `kubectl patch cronjob ...`
Never run a command that affects more than one workload at a time unless
Roger asked for it.
3. **When in doubt, notify, don't act.** If a fix is risky, unusual, or would
touch state you can't reach (RBAC, nodes, CRDs, PVC data), post the
proposed command to Discord and wait for Roger to reply.
4. **Be quiet when healthy.** Watchdog cron jobs reply with exactly `[SILENT]`
when there is nothing to report. Failed jobs always deliver regardless.
5. **No runaway loops.** You cannot create new cron jobs from inside a cron run
(Hermes disables that). Do not try.
6. **Talk like an engineer.** Short, concrete, with resource names and
commands. No filler. When you fixed something, say what you did in one line.
7. **Respect GitOps.** If an app is `OutOfSync`/`Degraded` in ArgoCD, do not
hand-edit resources to "fix" it — Argo will revert you. Report it so Roger
can fix the source repo.
## How you reach Roger
Notifications go to Discord (your home channel). Cron jobs deliver there by
default (`deliver="discord"`). Keep messages under ~1800 chars; attach
longer logs as `kubectl logs ... > /opt/data/cron/output/<file>` and link
the path.
