module: proxmox
short_description: Management of instances in Proxmox VE cluster
description:
  - Allows you to create/delete/stop instances in Proxmox VE cluster.
  - The module 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 O(proxmox_default_behavior).
attributes:
  check_mode:
    support: none

  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 O(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.

  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 V(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 V(no_defaults),
        which makes sure these options have no defaults.
      - This affects the O(disk), O(cores), O(cpus), O(memory), O(onboot), O(swap), and O(cpuunits) options.
      - >
        This parameter is now B(deprecated) and it will be removed in community.general 10.0.0.
        By then, the module's behavior should be to not set default values, equivalent to V(no_defaults).
        If a consistent set of defaults is needed, the playbook or role should be responsible for setting it.
    type: str

    choices:
      - compatibility
      - no_defaults
    version_added: "1.3.0"

    description:
      - ID of the container to be cloned.
      - O(description), O(hostname), and O(pool) will be copied from the cloned container if not specified.
      - The type of clone created is defined by the O(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.
      - V(full) creates a full clone, and O(storage) must be specified.
      - V(linked) creates a linked clone, and the cloned container must be a template container.
      - V(opportunistic) creates a linked clone if the cloned container is a template container, and a full clone if not.
        O(storage) may be specified, if not it will fall back to the default.
    type: str
    choices: ['full', 'linked', 'opportunistic']
    default: opportunistic
