To install manually, clone the Amazon VPC CNI for Kubernetes repository to your local machine:

$ git clone https://github.com/aws/amazon-vpc-cni-k8s.git

Use the helm install command to install the chart into your Kubernetes cluster:

$ helm install cni-metrics-helper --namespace kube-system ./charts/cni-metrics-helper

To uninstall:

$ helm uninstall cni-metrics-helper --namespace kube-system
