module: vmware_host
short_description: Add, remove, or move an ESXi host to, from, or within vCenter
description:
- This module can be used to add, reconnect, or remove an ESXi host to or from vCenter.
- This module can also be used to move an ESXi host to a cluster or folder, or vice versa, within the same datacenter.
version_added: '2.0'
author:
- Joseph Callen (@jcpowermac)
- Russell Teague (@mtnbikenc)
- Maxime de Roucy (@tchernomax)
- Christian Kotte (@ckotte)
notes:
- Tested on vSphere 5.5, 6.0, 6.5 and 6.7
requirements:
- python >= 2.6
- PyVmomi
- ssl
- socket
- hashlib
options:
  datacenter_name:
    description:
    - Name of the datacenter to add the host.
    - Aliases added in version 2.6.
    required: yes
    aliases: ['datacenter']
    type: str
  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']
    type: str
  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: "

    - This parameter is ignored if state is set to a value other than C(present).
    default: True

  esxi_hostname:
    description:
    - ESXi hostname to manage.
    required: yes
    type: str
  esxi_username:
    description:
    - ESXi username.
    - Required for adding a host.
    - Optional for reconnect. If both C(esxi_username) and C(esxi_password) are used
    - Unused for removing.
    - No longer a required parameter from version 2.5.
    type: str
  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.
    type: str
  state:
    description:
    - If set to C(present), add the host if host is absent.
    - If set to C(present), update the location of the host if host already exists.
    - If set to C(absent), remove the host if host is present.
    - If set to C(absent), do nothing if host already does not exists.
    - If set to C(add_or_reconnect), add the host if it's absent else reconnect it and update the location.
    - If set to C(reconnect), then reconnect the host if it's present and update the location.
    default: present
    choices: ['present', 'absent', 'add_or_reconnect', 'reconnect']

    version_added: 2.5
    default: ''
    type: str
    aliases: ['ssl_thumbprint']
  fetch_ssl_thumbprint:
    description:
    - Fetch the thumbprint of the host's SSL certificate.
    - This basically disables the host certificate verification (check if it was signed by a recognized CA).
    - Disable this option if you want to allow only hosts with valid certificates to be added to vCenter.
    - If this option is set to C(false) and the certificate can't be verified, an add or reconnect will fail.
    - Unused when C(esxi_ssl_thumbprint) is set.
    - Optional for reconnect, but only used if C(esxi_username) and C(esxi_password) are used.
    - Unused for removing.
    type: bool

    description:
    - Force the connection if the host is already being managed by another vCenter server.
    type: bool
    version_added: 2.8
    default: True
  reconnect_disconnected:
    description:
    - Reconnect disconnected hosts.
