Kubernetes RDF exporter

Quick Start

Using npx

npx @zazuko/k8s-rdf-exporter

Using the default configured cluster

npm i # install dependencies
npm run build # build everything
npm run start

Using explicit credentials

npm i # install dependencies
npm run build # build everything

# deploy in the `kube-system` namespace in the current cluster
#   - `k8s-rdf-exporter` ServiceAccount
#   - `k8s-rdf-exporter` Secret (it will contain the ServiceAccount credentials, this will be automatically filled)
#   - `k8s-rdf-exporter` ClusterRoleBinding, that gives the SA the `view` ClusterRole
(cd k8s && kustomize build | kubectl apply -f -)

export K8S_CLUSTER_NAME=$(kubectl config view --minify -o 'jsonpath={.clusters[0].name}')
export K8S_API_URL=$(kubectl config view --minify -o 'jsonpath={.clusters[0].cluster.server}')
export K8S_SERVICE_TOKEN=$(kubectl -n kube-system get secret k8s-rdf-exporter -o jsonpath='{.data.token}' | base64 -d)
export K8S_CERTIFICATE_PATH="/tmp/k8s-rdf-exporter-cert.txt"

kubectl -n kube-system get secret k8s-rdf-exporter \
  -o jsonpath='{.data.ca\.crt}' | base64 -d > "${K8S_CERTIFICATE_PATH}"

node dist/cli.js \
  --api-url="${K8S_API_URL}" \
  --cluster-name="${K8S_CLUSTER_NAME}" \
  --certificate-path="${K8S_CERTIFICATE_PATH}" \
  --service-token="${K8S_SERVICE_TOKEN}"
