cache boolean | Choices: no ← yes | ini entries: [inventory] cache = no env:ANSIBLE_INVENTORY_CACHE | Toggle to enable/disable the caching of the inventory's source data, requires a cache plugin setup to work.
cache_connection string |  | ini entries: [defaults] fact_caching_connection = VALUE [inventory] cache_connection = VALUE env:ANSIBLE_CACHE_PLUGIN_CONNECTION env:ANSIBLE_INVENTORY_CACHE_CONNECTION | Cache connection data or path, read cache plugin documentation for specifics.
cache_plugin string | Default: "memory" | ini entries: [defaults] fact_caching = memory [inventory] cache_plugin = memory env:ANSIBLE_CACHE_PLUGIN env:ANSIBLE_INVENTORY_CACHE_PLUGIN | Cache plugin to use for the inventory's source data.
cache_prefix - | Default: "ansible_inventory_" | ini entries: [default] fact_caching_prefix = ansible_inventory_ [inventory] cache_prefix = ansible_inventory_ env:ANSIBLE_CACHE_PLUGIN_PREFIX env:ANSIBLE_INVENTORY_CACHE_PLUGIN_PREFIX | Prefix to use for cache plugin files/tables

| annotation_variable string | Default: "ansible" |  | Specify the name of the annotation which provides data, which should be used as inventory host variables. Note, that the value in ansible annotations should be json.
| api_key string |  |  | Token used to authenticate with the API. Can also be specified via K8S_AUTH_API_KEY environment variable.
| api_version string |  |  | Specify the KubeVirt API version.
| cert_file string |  |  | Path to a certificate used to authenticate with the API. Can also be specified via K8S_AUTH_CERT_FILE environment variable.
| context string |  |  | The name of a context found in the config file. Can also be specified via K8S_AUTH_CONTEXT environment variable.
| host string |  |  | Provide a URL for accessing the API. Can also be specified via K8S_AUTH_HOST environment variable.

plugin string / required | Choices: kubevirt |  | token that ensures this is a source file for the 'kubevirt' plugin.
strict boolean | Choices: no ← yes |  | If `yes` make invalid entries a fatal error, otherwise skip and continue. Since it is possible to use facts in the expressions they might not always be available and we ignore those errors by default.

## Examples

    # File must be named kubevirt.yaml or kubevirt.yml

    # Authenticate with token, and return all virtual machines for all namespaces
    plugin: kubevirt
    connections:
     - host: https://kubevirt.io
       token: xxxxxxxxxxxxxxxx
       ssl_verify: false

    # Use default config (~/.kube/config) file and active context, and return vms with interfaces
    # connected to network myovsnetwork and from namespace vms
    plugin: kubevirt
    connections:
      - namespaces:
          - vms
        network_name: myovsnetwork

Hint

Configuration entries for each entry type have a low to high priority order. For example, a variable that is lower in the list will override a variable that is higher up.
