# ✅ Create namespace + secret (idempotent)
kubectl create namespace datadog --dry-run=client -o yaml | kubectl apply -f -
kubectl create secret generic datadog-secret \
  --from-literal=api-key="${DD_API_KEY}" \
  -n datadog \
  --dry-run=client -o yaml | kubectl apply -f -

# ✅ Reference secret in Helm values
helm upgrade --install datadog datadog/datadog \
  --set datadog.apiKeyExistingSecret=datadog-secret \
  --create-namespace \
  -n datadog

# ❌ Never pass key on command line — stored in Helm release history
# helm upgrade --install datadog datadog/datadog --set datadog.apiKey="${DD_API_KEY}"

// dd-trace init — must be first import
