Labelling and assign roles on nodes On this page If you want to add labels and assign roles to your nodes, you must edit the Cluster object, and add the labels under spec.topology.workers.metadata
:
workers:
machineDeployments:
- class: workeramd64hcloud
name: md-0
replicas: 5
failureDomain: nbg1
metadata: // [!code ++]
labels: // [!code ++]
node-role.kubernetes.io/backend: 'true' // [!code ++]
node.cluster.x-k8s.io/environment: 'production' // [!code ++]
variables:
overrides:
- name: workerMachineTypeHcloud
value: cpx31
- name: workerMachinePlacementGroupNameHcloud
value: md-0
For the label to propagate to the node in the workload cluster, it should meet one of the following criteria:
Has node-role.kubernetes.io as prefix, e.g. node-role.kubernetes.io/worker: ''
Belongs to node-restriction.kubernetes.io domain, e.g. node-restriction.kubernetes.io/location: 'fsn1'
Belongs to node.cluster.x-k8s.io domain, e.g. node.cluster.x-k8s.io/environment: 'production'
You can create new machine deployments and separate your node labels however you like. For example, you might have the same five machines, but three with label node.cluster.x-k8s.io/environment: production
and two with node.cluster.x-k8s.io/environment: staging
