Node pool¶

node labels and node taints¶

node_labels - (Optional) A map of Kubernetes labels which should be applied to nodes in this Node Pool.
node_taints - (Optional) A list of Kubernetes taints which should be applied to nodes in the agent pool (e.g key=value:NoSchedule). Changing this forces a new resource to be created.

These properties can be used to only allow some pods to be deployed in this node pool.

# https://registry.terraform.io/providers/hashicorp/azurerm/latest/docs/resources/kubernetes_cluster_node_pool
resource "azurerm_kubernetes_cluster_node_pool" "np01" {
...
  node_labels = {
    "hub.jupyter.org/node-purpose" = "dev-user"
  }
  node_taints = [
    "hub.jupyter.org/dedicated=dev-user:NoSchedule"
  ]
}

And in jupyterhub values.yaml
