## How you observe the cluster (NO kubectl — you have none) ## How you observe the cluster (NO kubectl — you have none)
You have NO k8s API access and NO kubectl. Use these HTTP APIs instead: You have NO k8s API access and NO kubectl. DO NOT try to run kubectl — it
is not installed and you have no RBAC. Use the HTTP APIs below with the
terminal tool. Use in-cluster service hostnames (name.namespace:port),
NOT public ingress URLs like loki.rogi.casa (they go through Cloudflare
which times out on long requests).
1. **Prometheus** (metrics) at `http://prometheus.monitoring:9090/api/v1/query` ### 1. Prometheus (metrics)
— PromQL via `curl -G -s "http://prometheus.monitoring:9090/api/v1/query" --data-urlencode "query=<PROMQL>"` Endpoint: http://prometheus.monitoring:9090/api/v1/query
Examples: Use the terminal tool to send an HTTP GET with a PromQL query parameter
- Node Ready: `kube_node_status_condition{condition="Ready",status="true"}` named 'query'. Useful PromQL:
- Node CPU/mem: `node_memory_MemAvailable_bytes`, `node_cpu_seconds_total` - Node not Ready: kube_node_status_condition{condition="Ready",status!="true"}
- Pod restarts: `kube_pod_container_status_restarts_total` - Pod not Running: kube_pod_status_phase{phase!="Running"}
- PVC usage: `kubelet_volume_stats_available_bytes / kubelet_volume_stats_capacity_bytes` - Pod restarts: kube_pod_container_status_restarts_total
- Cert expiry: `certmanager_certificate_expiration_timestamp_seconds` - PVC free percent: kubelet_volume_stats_available_bytes / kubelet_volume_stats_capacity_bytes
- Node mem free: node_memory_MemAvailable_bytes / node_memory_MemTotal_bytes
- Node disk used: 1 - (node_filesystem_avail_bytes{mountpoint="/"} / node_filesystem_size_bytes{mountpoint="/"})
- Cert expiry (days): (certmanager_certificate_expiration_timestamp_seconds - time()) / 86400
- Top pods CPU: topk(5, rate(container_cpu_usage_seconds_total[5m]))
- Top pods mem: topk(5, container_memory_working_set_bytes)
2. **Loki** (pod logs + events) at `http://loki.monitoring:3100/loki/api/v1/query_range` ### 2. Loki (pod logs)
— LogQL via `curl -G -s "http://loki.monitoring:3100/loki/api/v1/query_range" --data-urlencode "query=<LOGQL>" --data-urlencode "start=<unix_ns>" --data-urlencode "end=<unix_ns>" --data-urlencode "limit=50"` Endpoint: http://loki.monitoring:3100/loki/api/v1/query_range
Examples: Use the terminal tool to send an HTTP GET with these query parameters:
- Errors in a namespace: `{namespace="myorg-assistant"} |= "error"` 'query' (a LogQL expression), 'start' and 'end' (Unix nanosecond
- CrashLoop across cluster: `{namespace=~".+"} |= "BackOff"` timestamps), and 'limit'. Useful LogQL:
- k8s events: `{app="k8s-event-logger"} |= "Warning"` - Errors in a namespace: {namespace="myorg-assistant"} |= "error"
- CrashLoop across cluster: {namespace=~".+"} |~ "(?i)backoff|crashloop"
- Pod logs: {namespace="<ns>",pod="<pod>"}
3. **ArgoCD API** at `https://argocd-server.argocd:443` — bearer token in ### 3. ArgoCD API (app status + sync triggers)
`$ARGOCD_API_TOKEN`. (Verify the cert with `--insecure` if needed since Endpoint: https://argocd-server.argocd:443 (internal service, use the -k
it's the internal service.) flag to skip TLS cert verification since it's a self-signed internal cert)
Examples: Auth: bearer token (read from the environment variable for the ArgoCD token). Send an
- List apps: `curl -sk -H "Authorization: Bearer $ARGOCD_API_TOKEN" https://argocd-server.argocd:443/api/v1/applications` Authorization header with the token.
- Sync an app: `curl -sk -X POST -H "Authorization: Bearer $ARGOCD_API_TOKEN" https://argocd-server.argocd:443/api/v1/applications/<app>/sync` Endpoints: GET /api/v1/applications (list apps), POST /api/v1/applications/<app>/sync (trigger sync)
## Parsing JSON responses
The execute_code tool is BLOCKED in cron mode. To parse JSON from HTTP
responses, pipe the output through python3 or jq inside the terminal tool.
