### Step One: Attach label to the node
Run `kubectl get nodes` to get the names of your cluster's nodes. Pick out the one that you want to add a label to.
Then, to add a label to the node you've chosen, run `kubectl label nodes <node-name> <label-key>=<label-value>`. For example, if my node name is 'kubernetes-foo-node-1.c.a-robinson.internal' and my desired label is 'disktype=ssd', then I can run `kubectl label nodes kubernetes-foo-node-1.c.a-robinson.internal disktype=ssd`.

If this fails with an "invalid command" error, you're likely using an older version of kubectl that doesn't have the `label` command. In that case, see the [previous version](https://github.com/kubernetes/kubernetes/blob/a053dbc313572ed60d89dae9821ecab8bfd676dc/examples/node-selection/README.md) of this guide for instructions on how to manually set labels on a node.
