+# GNP-Stack
+
+This directory contains Kubernetes manifests for deploying the GNP-Stack to a Kubernetes cluster via Helm.
+
+
+## Setup Demo Cluster
+
+Using [talosctl](https://docs.siderolabs.com/talos/v1.11/getting-started/talosctl), you can quickly set up a local Kubernetes cluster for testing and development purposes.
+```bash
+talosctl cluster create --cidr 192.168.60.0/24 --name gnp-stack_gnp-mgmt --wait=false --config-patch '{"cluster":{"network":{"cni":{"name":"none"}},"proxy":{"disabled":true}}}' --cpus-workers 12.0 --memory-workers 12000
+talosctl kubeconfig -n 192.168.60.2 .
+kubectl config view --flatten --kubeconfig ./kubeconfig > ~/.kube/config
+```
+
+Cilium installation:
+```bash
+helm repo add cilium https://helm.cilium.io
+helm repo update
+helm upgrade --install cilium cilium/cilium \
+ --version 1.18.3 \
+ --namespace kube-system \
+ --values - <<'EOF'

+```bash
+helm upgrade --install gnp-stack ./gnp-stack --namespace gnp-stack --create-namespace
+```
+
+## Old install all components separately
+Setup namespace:
+```bash
+kubectl create namespace gnp-stack

+helm repo update
+helm upgrade --install nats nats/nats --namespace gnp-stack --version 2.12.1 -f nats/values.yaml
+```
+
+GNMIC Ingestor and Emitter:
+```bash
+kubectl apply -f gnmic-ingestor
+kubectl apply -f gnmic-emitter
+```
+
+
+## Cleanup demo cluster
+```bash
+talosctl cluster destroy --name gnp-stack_gnp-mgmt
+```
