List Node Labels from the CLIΒΆ
You can list assigned labels to review and manage the scheduling of Kubernetes objects, such as pods.
Labels are key/value pairs that are attached to nodes and are used to specify identifying attributes of nodes. Labels can be used to identify physical attributes of a node such as special purpose hardware or labels can be used to identify logical attributes of a node, for example the role of a node.
For more information on labels that are used to assign pods to nodes, refer to https://kubernetes.io/docs/concepts/configuration/assign-pod-node/.
Procedure
To list labels currently assigned to a host, use the host-label-list command.
The command format is:
system host-label-list (<hostName> | <hostID>)
For example:
~(keystone)admin)$ system host-label-list controller-0 +--------------+-------------------------+-------------+ | hostname | label key | label value | +--------------+-------------------------+-------------+ | controller-0 | openstack-compute-node | enabled | | controller-0 | openstack-control-plane | enabled | | controller-0 | openvswitch | enabled | | controller-0 | SRIOV | enabled | +--------------+-------------------------+-------------+
