`lookupEffectiveGuestPolicy(instance, body=None, x__xgafv=None)`

    Lookup the effective guest policy that applies to a VM instance. This lookup merges all policies that are assigned to the instance ancestry.

    Args:
      instance: string, Required. The VM instance whose policies are being looked up. (required)
      body: object, The request body.
        The object takes the form of:

    { # A request message for getting the effective guest policy assigned to the instance.
        "osShortName": "A String", # Short name of the OS running on the instance. The OS Config agent only provides this field for targeting if OS Inventory is enabled for that instance.
        "osVersion": "A String", # Version of the OS running on the instance. The OS Config agent only provides this field for targeting if OS Inventory is enabled for that VM instance.
        "osArchitecture": "A String", # Architecture of OS running on the instance. The OS Config agent only provides this field for targeting if OS Inventory is enabled for that instance.
      }

      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:
      An object of the form:

        { # The effective guest policy that applies to a VM instance.
        "softwareRecipes": [ # List of recipes assigned to the VM instance.

It consists of a set of artifacts that are downloaded, and a set of steps that install, configure, and/or update the software. Recipes support installing and updating software from artifacts in the following formats: Zip archive, Tar archive, Windows MSI, Debian package, and RPM package. Additionally, recipes support executing a script (either defined in a file or directly in this api) in bash, sh, cmd, and powershell. Updating a software recipe If a recipe is assigned to an instance and there is a recipe with the same name but a lower version already installed and the assigned state of the recipe is `UPDATED`, then the recipe is updated to the new version. Script Working Directories Each script or execution step is run in its own temporary directory which is deleted after completing the step. # A software recipe to configure on the VM instance.
              "name": "A String", # Required. Unique identifier for the recipe. Only one recipe with a given name is installed on an instance.

INSTALLED: The software recipe is installed on the instance but won't be updated to new versions. UPDATED: The software recipe is installed on the instance. The recipe is updated to a higher version, if a higher version of the recipe is assigned to this instance.
