- name: Manage nodePool
  hosts: localhost
  vars:
    ansible_python_interpreter: `<point-to-python-env-where-collection-is-installed>`
  collections:
    - linode.cloud
  tasks:
    - name: Create a Linode LKE node pool with autoscaler
      linode.cloud.lke_node_pool:
        api_version: v4beta
        cluster_id: <cluster-id>
      
        tags: ['my-pool']
        count: 4
        type: g6-standard-2
        label: my-second-pool
        
        autoscaler:
            enabled: true
            min: 1
            max: 5

        state: present
      register: node_pool

    - name: Output node pool details
      debug:
        var: node_pool

    - name: Create a Linode LKE node pool with autoscaler
      linode.cloud.lke_node_pool:
        api_version: v4beta
        cluster_id: <cluster-id>
      
        tags: ['my-pool']
        state: absent

• To test cluster creation. Use below playbook:

- name: Manage nodePool
  hosts: localhost
  vars:
    ansible_python_interpreter: `<point-to-python-env-where-collection-is-installed>`
  collections:
    - linode.cloud
  tasks:
    - name: Create a Linode LKE cluster with autoscaler
      linode.cloud.lke_cluster:
        api_version: v4beta
        label: 'my-cluster'
        region: us-ord
        k8s_version: v1.31.8+lke5
        tier: enterprise
        node_pools:
          - type: g6-standard-1
            count: 2
            label: 'my-first-nodepool'
        state: present
      register: cluster

    - name: Output cluster details
      debug:
        var: cluster
