README

k8s-node-tagger

A Kubernetes controller that watches Kubernetes Nodes and copies labels from the node to the cloud provider's VM as tags (AWS) or labels (GCP).

Testing

• lint: make lint
• test: make test

Running it locally is possible too. The standard mechanisms for finding the current kubeconfig and aws/gcp credentials are used.

Assuming you use ~/.aws/config and have profiles defined you could run:

AWS_PROFILE=my-profile AWS_REGION=region go run -v .

For GCP you want to ensure you have application default credentials setup by running either gcloud auth login --update-adc or gcloud auth application-default login.

Inspiration

Inspired by mtougeron/k8s-pvc-tagger which provides similar functionality for copying PVC labels to the underlying cloud provider's disk.
