Deploy OTEL Observability Stack

Deploy a complete OpenTelemetry observability stack to a Kind cluster for testing the registry server's telemetry capabilities.

Steps

1. Verify Prerequisites

Check that required tools are installed:

echo "Checking prerequisites..."
command -v kind >/dev/null 2>&1 || { echo "ERROR: kind is not installed"; exit 1; }
command -v helm >/dev/null 2>&1 || { echo "ERROR: helm is not installed"; exit 1; }
command -v kubectl >/dev/null 2>&1 || { echo "ERROR: kubectl is not installed"; exit 1; }
echo "All prerequisites met."

2. Create Kind Cluster

Create the Kind cluster if it doesn't exist:

CLUSTER_NAME="thv-registry"

if kind get clusters 2>/dev/null | grep -q "^${CLUSTER_NAME}$"; then
  echo "Kind cluster '${CLUSTER_NAME}' already exists"
else
  echo "Creating Kind cluster '${CLUSTER_NAME}'..."
  kind create cluster --name ${CLUSTER_NAME}
fi

# Export kubeconfig
kind get kubeconfig --name ${CLUSTER_NAME} > kconfig.yaml
echo "Kubeconfig written to kconfig.yaml"

3. Add Helm Repositories

echo "Adding Helm repositories..."
helm repo add open-telemetry https://open-telemetry.github.io/opentelemetry-helm-charts
helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
helm repo add grafana https://grafana.github.io/helm-charts
helm repo update
echo "Helm repositories updated."

4. Install Prometheus/Grafana Stack

echo "Installing kube-prometheus-stack..."
helm upgrade -i kube-prometheus-stack prometheus-community/kube-prometheus-stack \
  -f examples/otel/prometheus-stack-values.yaml \
  -n monitoring --create-namespace \
  --kubeconfig kconfig.yaml \
  --wait --timeout 5m

echo "Prometheus/Grafana stack installed."

5. Install Tempo for Distributed Tracing

echo "Installing Grafana Tempo..."
helm upgrade -i tempo grafana/tempo \
  -f examples/otel/tempo-values.yaml \
  -n monitoring \
  --kubeconfig kconfig.yaml \
  --wait --timeout 3m

echo "Grafana Tempo installed."
