At some point, the contents of ./roles/kubernetes/node/templates/kubelet.kubeadm.env.j2 included some node-role information inside {# Kubelet node labels #} --i.e. here.

However, now I cannot find any reference to node-role.kubernetes.io/node in the whole project. So it seems that this was removed.

A workaround is to use the node_labels variable. But, I like the default node annotation, makes sense for typical orchestration afaict.

Seems to be intended in commit 05dc2b3a097fda2ffff7a77f4ca843d0e41dec76. I assume that @mattymo was refering to this labeling behaviour of _node_ nodes in the

• Remove kubelet autolabel of kube-node (...)

[billykwooten]

Same thing here, node isn't showing up!

[woopstar]

The label node-role.kubernetes.io/node is not used and therefore removed in the commit. Only the label master is used in Kubespray.

[alexbarcelo]

I see. I assumed (just like @aiv, I suppose) that it was a pseudo-standard label, but by looking at kubeadm / kubernetes I understand that it's not, only the .../master one is.

[woopstar]

I'm closing the issue as this is not an error. You just don't have the label and since it is not used for anything this will not result in any errors.
