module: vmware_host
short_description: Add / Remove ESXi host to / from vCenter
description:
- This module can be used to add / remove / reconnect an ESXi host to / from vCenter.
version_added: '2.0'
author:
- Joseph Callen (@jcpowermac)
- Russell Teague (@mtnbikenc)
- Maxime de Roucy (@tchernomax)
notes:
- Tested on vSphere 5.5, 6.0 and 6.5
requirements:
- python >= 2.6
- PyVmomi
options:
  datacenter_name:
    description:
    - Name of the datacenter to add the host.
    - Aliases added in version 2.6.
    required: yes
    aliases: ['datacenter']
  cluster_name:
    description:
    - Name of the cluster to add the host.
    - If C(folder) is not set, then this parameter is required.
    - Aliases added in version 2.6.
    aliases: ['cluster']
  folder:
    description:
    - Name of the folder under which host to add.
    - If C(cluster_name) is not set, then this parameter is required.
    - "For example, if there is a datacenter 'dc1' under folder called 'Site1' then, this value will be '/Site1/dc1/host'."
    - "Here 'host' is an invisible folder under VMware Web Client."
    - "Another example, if there is a nested folder structure like '/myhosts/india/pune' under
       datacenter 'dc2', then C(folder) value will be '/dc2/host/myhosts/india/pune'."
    - "Other Examples: "
    - "  - '/Site2/dc2/Asia-Cluster/host'"
    - "  - '/dc3/Asia-Cluster/host'"
    version_added: "2.6"
  add_connected:
    description:
    - If set to C(True), then the host should be connected as soon as it is added.
    - This parameter is ignored if state is set to a value other than C(present).
    default: True
    type: 'bool'
    version_added: "2.6"
  esxi_hostname:
    description:
    - ESXi hostname to manage.
    required: yes
  esxi_username:
    description:
    - ESXi username.
    - Required for adding a host.
    - Optional for reconnect.
    - Unused for removing.
    - No longer a required parameter from version 2.5.
  esxi_password:
    description:
    - ESXi password.
    - Required for adding a host.
    - Optional for reconnect.
    - Unused for removing.
    - No longer a required parameter from version 2.5.
  state:
    description:
    - If set to C(present), then add the host if host is absent.
    - If set to C(present), then do nothing if host already exists.
    - If set to C(absent), then remove the host if host is present.
    - If set to C(absent), then do nothing if host already does not exists.
    - If set to C(add_or_reconnect), then add the host if it's absent else reconnect it.
    - If set to C(reconnect), then reconnect the host if it's present else fail.
    default: present
    choices: ['present', 'absent', 'add_or_reconnect', 'reconnect']
  esxi_ssl_thumbprint:
    description:
    - "Specifying the hostsystem certificate's thumbprint."
    - "Use following command to get hostsystem certificate's thumbprint - "
