Overview

Handler for listing templates (both VM and container).

Queries both VM and Container repositories, filters by template? == true, and merges into a single list. Supports –type flag for filtering by resource type (vm/ct/qemu/lxc).

Examples:

Using via ResourceRegistry

handler = ResourceRegistry.for("templates")
templates = handler.list(type_filter: "vm")

TYPE_MAP =

Type filter mapping — normalizes user input to API type values.

{
  "vm" => "qemu",
  "qemu" => "qemu",
  "ct" => "lxc",
  "container" => "lxc",
  "lxc" => "lxc"
}.freeze
SORT_FIELDS =

Sort field mappings for template listing.

{
  "name" => ->(t) { t.name || "" },
  "node" => ->(t) { t.node || "" },
  "type" => ->(t) { t.type || "" },
  "disk" => ->(t) { -(t.maxdisk || 0) }
}.freeze

Parameters:

  • node (String, nil) (defaults to: nil) —

    filter by node name

  • type_filter (String, nil) (defaults to: nil) —

    filter by type (vm, ct, qemu, lxc)

  • sort (String, nil) (defaults to: nil) —

    sort field

  • name (String, nil) (defaults to: nil) —

    unused, interface compatibility

Returns:

Raises:

  • (ArgumentError) —
