module: proxmox
short_description: management of instances in Proxmox VE cluster
description:
  - allows you to create/delete/stop instances in Proxmox VE cluster
  - Starting in Ansible 2.1, it automatically detects containerization type (lxc for PVE 4, openvz for older)
  - Since community.general 4.0.0 on, there are no more default values, see I(proxmox_default_behavior).
options:
  password:
    description:
      - the instance root password
    type: str
  hostname:
    description:
      - the instance hostname
      - required only for C(state=present)
      - must be unique if vmid is not passed
    type: str
  ostemplate:
    description:
      - the template for VM creating
      - required only for C(state=present)
    type: str
  disk:
    description:
      - This option was previously described as "hard disk size in GB for instance" however several formats describing
        a lxc mount are permitted.
      - Older versions of Proxmox will accept a numeric value for size using the I(storage) parameter to automatically
        choose which storage to allocate from, however new versions enforce the C(<STORAGE>:<SIZE>) syntax.
      - "Additional options are available by using some combination of the following key-value pairs as a
        comma-delimited list C([volume=]<volume> [,acl=<1|0>] [,mountoptions=<opt[;opt...]>] [,quota=<1|0>]
        [,replicate=<1|0>] [,ro=<1|0>] [,shared=<1|0>] [,size=<DiskSize>])."
      - See U(https://pve.proxmox.com/wiki/Linux_Container) for a full description.
      - This option has no default unless I(proxmox_default_behavior) is set to C(compatiblity); then the default is C(3).
    type: str
  cores:
    description:
      - Specify number of cores per socket.
      - This option has no default unless I(proxmox_default_behavior) is set to C(compatiblity); then the default is C(1).
    type: int
  cpus:
    description:
      - numbers of allocated cpus for instance
      - This option has no default unless I(proxmox_default_behavior) is set to C(compatiblity); then the default is C(1).
    type: int
  memory:
    description:

    type: int
  swap:
    description:
      - swap memory size in MB for instance
      - This option has no default unless I(proxmox_default_behavior) is set to C(compatiblity); then the default is C(0).
    type: int
  netif:
    description:
      - specifies network interfaces for the container. As a hash/dictionary defining interfaces.
    type: dict
  features:
    description:
      - Specifies a list of features to be enabled. For valid options, see U(https://pve.proxmox.com/wiki/Linux_Container#pct_options).
      - Some features require the use of a privileged container.
    type: list
    elements: str
    version_added: 2.0.0

  hookscript:
    description:
      - Script that will be executed during various steps in the containers lifetime.
    type: str
    version_added: '0.2.0'
  proxmox_default_behavior:
    description:
      - As of community.general 4.0.0, various options no longer have default values.
        These default values caused problems when users expected different behavior from Proxmox
        by default or filled options which caused problems when set.
      - The value C(compatibility) (default before community.general 4.0.0) will ensure that the default values
        are used when the values are not explicitly specified by the user. The new default is C(no_defaults),
        which makes sure these options have no defaults.
      - This affects the I(disk), I(cores), I(cpus), I(memory), I(onboot), I(swap), I(cpuunits) options.
    type: str
    default: no_defaults
    choices:
      - compatibility

      - I(description), I(hostname), and I(pool) will be copied from the cloned container if not specified.
      - The type of clone created is defined by the I(clone_type) parameter.
      - This operator is only supported for Proxmox clusters that use LXC containerization (PVE version >= 4).
    type: int
    version_added: 4.3.0
  clone_type:
    description:
      - Type of the clone created.
      - C(full) creates a full clone, and I(storage) must be specified.
      - C(linked) creates a linked clone, and the cloned container must be a template container.
      - C(opportunistic) creates a linked clone if the cloned container is a template container, and a full clone if not.
        I(storage) may be specified, if not it will fall back to the default.
    type: str
    choices: ['full', 'linked', 'opportunistic']
    default: opportunistic
