+# Kubernetes
+
+Common tasks when running Epimetheus against Prometheus, Pushgateway, and Grafana in Kubernetes.
+
+## Port-forwards
+
+To run Epimetheus on your laptop against cluster services:
+
+```bash
+# Pushgateway (realtime mode)
+kubectl port-forward -n monitoring svc/pushgateway 9091:9091 &
+
+# Prometheus (historic/watch, queries)
+kubectl port-forward -n monitoring svc/prometheus-kube-prometheus-prometheus 9090:9090 &
+
+# Grafana (dashboards)
+kubectl port-forward -n monitoring svc/prometheus-grafana 3000:80
+```
+
+Then use `http://localhost:9091`, `http://localhost:9090`, and `http://localhost:3000` in Epimetheus flags and in the browser. Adjust service names and namespaces to match your cluster (e.g. `prometheus-kube-prometheus-prometheus` for kube-prometheus-stack).
+
+## Deploying Pushgateway
+
+Example using the official Helm chart:
+
+```bash
+helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
+helm install pushgateway prometheus-community/prometheus-pushgateway -n monitoring --create-namespace
+```
+
+Alternatively use your own chart (e.g. from the [conf repository](https://codeberg.org/snonux/conf) at `f3s/pushgateway/helm-chart`).
+
+## Deploying the Epimetheus Grafana dashboard
+
+**ConfigMap (recommended):** If you have a manifest that creates a ConfigMap with the dashboard JSON and the Grafana label for auto-discovery:
+
+```bash
+kubectl apply -f ../prometheus/epimetheus-dashboard.yaml
+```
+
+**Script:** From the repo, with Grafana reachable (e.g. after port-forward):
+
+```bash
+./scripts/deploy-dashboard.sh
+# Or with credentials:
+GRAFANA_URL="http://localhost:3000" GRAFANA_USER="admin" GRAFANA_PASSWORD="yourpassword" ./scripts/deploy-dashboard.sh
+```
+
+## Namespace and service names
+
+Replace `monitoring` and the Prometheus/Pushgateway/Grafana service names with whatever your Helm release or manifests use. Epimetheus only needs the URLs; it does not need to run inside the cluster.
