Node labeler

Zuul

This is a very small tool that can run as a DaemonSet inside your Kubernetes cluster which will automatically label your nodes based on the product and vendor. This can help with things like running specific monitoring tools on specific hardware.

This is an example of labeled Dell PowerEdge machine:

Labels:             beta.kubernetes.io/arch=amd64
                    beta.kubernetes.io/os=linux
                    kubernetes.io/arch=amd64
                    kubernetes.io/hostname=<snip>
                    kubernetes.io/os=linux
                    node-role.kubernetes.io/master=
                    node.vexxhost.com/product=poweredge-r640
                    node.vexxhost.com/vendor=dell-inc

In addition, we provide a very simple manifest attached inside this repository which helps you setup a service account that is locked down to only GET and PATCH nodes in the Kubernetes API with the code for a DaemonSet. It shouldn't require any changes to get going on your cluster.
