module: vsphere_copy
short_description: Copy a file to a vCenter datastore
description:
    - Upload files to a vCenter datastore
version_added: 2.0
author:
- Dag Wieers (@dagwieers)
options:
  host:
    description:
      - The vCenter server on which the datastore is available.
    required: true
    aliases: ['hostname']
  login:
    description:
      - The login name to authenticate on the vCenter server.
    required: true
    aliases: ['username']
  password:
    description:
      - The password to authenticate on the vCenter server.
    required: true
  src:
    description:
      - The file to push to vCenter
    required: true
  datacenter:
    description:
      - The datacenter on the vCenter server that holds the datastore.
    required: true
  datastore:
    description:
      - The datastore on the vCenter server to push files to.
    required: true
  path:
    description:
      - The file to push to the datastore on the vCenter server.
    required: true
  validate_certs:
    description:
      - If C(no), SSL certificates will not be validated. This should only be
        set to C(no) when no other option exists.
    default: 'yes'
    type: bool

notes:
  - "This module ought to be run from a system that can access vCenter directly and has the file to transfer.
    It can be the normal remote target or you can change it either by using C(transport: local) or using C(delegate_to)."
  - Tested on vSphere 5.5
