EXAMPLES = r"""
#
#
# The examples below assume you have a datacenter named 'my_dc', a cluster named 'my_cluster', and a resource pool named 'my_pool'.
# Replace these values as needed for your environment.
#
#

#
# Authentication / Connection Arguments
#
# You can explicitly set the connection arguments in each lookup. This may be clearer for some use cases
- name: Pass In Connection Arguments Explicitly

      vcenter_hostname="vcenter.test",
      vcenter_username="administrator@vsphere.local",
      vcenter_password="1234") }}

# Alternatively, you can add the connection arguments to a dictionary variable, and then pass that variable to the
# lookup plugins. This makes the individual lookup plugin calls simpler

#
# Resource Pool Search Path Examples
#
# Pools are located under the 'host' folder in a datacenter. They are nested under the cluster name, and
# then a special 'Resources' folder.
# The basic path for a pool should look like '/<datacenter-name>/host/<cluster-name>/Resources/<resource-pool-name>'
- name: Lookup Pool Named 'my_pool' in Datacenter 'my_dc' and Cluster 'my_cluster'
  ansible.builtin.debug:
    msg: "{{ lookup('vmware.vmware_rest.resource_pool_moid', '/my_dc/host/my_cluster/Resources/my_pool') }}"

#
# Usage in Playbooks
#
#
# The lookup plugin can be used to simplify your playbook. Here is an example of how you might use it.
#
# Without the lookup, this takes two modules which both run on the remote host. This can slow down execution
# and adds extra steps to the playbook:
- name: Retrieve details about a resource pool named 'my_pool'
  vmware.vmware_rest.vcenter_resource_pool_info:
    names:
      - my_pool
  register: my_pool_info

- name: Create a VM
  vmware.vmware_rest.vcenter_vm:
    placement:
      resource_pool: "{{ my_pool_info.value[0].resource_pool }}"
    name: test_vm1
    guest_OS: RHEL_7_64
    hardware_version: VMX_11
    memory:
      size_MiB: 1024
    disks:
      - type: SATA
        new_vmdk:
          name: first_disk
          capacity: 3200

# With the lookup, playbooks are shorter, quicker, and more intuitive:
- name: Create a VM
  vmware.vmware_rest.vcenter_vm:
    placement:
      resource_pool: "{{ lookup('vmware.vmware_rest.resource_pool_moid', '/my_dc/host/my_cluster/Resources/my_pool') }}"
    name: test_vm1
    guest_OS: RHEL_7_64
    hardware_version: VMX_11
    memory:
      size_MiB: 1024
    disks:
      - type: SATA
        new_vmdk:
          name: first_disk
          capacity: 3200
