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)
  - From community.general 4.0.0 on, there will be no 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.
      - If I(proxmox_default_behavior) is set to C(compatiblity) (the default value), this
        option has a default of C(3). Note that the default value of I(proxmox_default_behavior)
        changes in community.general 4.0.0.
    type: str
  cores:
    description:
      - Specify number of cores per socket.
      - If I(proxmox_default_behavior) is set to C(compatiblity) (the default value), this
        option has a default of C(1). Note that the default value of I(proxmox_default_behavior)
        changes in community.general 4.0.0.
    type: int
  cpus:
    description:
      - numbers of allocated cpus for instance
      - If I(proxmox_default_behavior) is set to C(compatiblity) (the default value), this
        option has a default of C(1). Note that the default value of I(proxmox_default_behavior)
        changes in community.general 4.0.0.
    type: int
  memory:
    description:
      - memory size in MB for instance
      - If I(proxmox_default_behavior) is set to C(compatiblity) (the default value), this
        option has a default of C(512). Note that the default value of I(proxmox_default_behavior)
        changes in community.general 4.0.0.
    type: int
  swap:
    description:
      - swap memory size in MB for instance
      - If I(proxmox_default_behavior) is set to C(compatiblity) (the default value), this
        option has a default of C(0). Note that the default value of I(proxmox_default_behavior)
        changes in community.general 4.0.0.
    type: int

    type: str
  onboot:
    description:
      - specifies whether a VM will be started during system bootup
      - If I(proxmox_default_behavior) is set to C(compatiblity) (the default value), this

      - with states C(stopped) , C(restarted) allow to force stop instance
    type: bool
    default: 'no'
  purge:
    description:
      - Remove container from all related configurations.
      - For example backup jobs, replication jobs, or HA.

  proxmox_default_behavior:
    description:
      - Various module options used to have default values. This cause problems when
        user expects different behavior from proxmox by default or fill options which cause
        problems when they have been set.
      - The default value is C(compatibility), which will ensure that the default values
        are used when the values are not explicitly specified by the user.
      - From community.general 4.0.0 on, the default value will switch to C(no_defaults). To avoid
        deprecation warnings, please set I(proxmox_default_behavior) to an explicit
        value.
      - This affects the I(disk), I(cores), I(cpus), I(memory), I(onboot), I(swap), I(cpuunits) options.
    type: str
    choices:
      - compatibility
      - no_defaults
