# Module `netapp_ontap.resources.dns`

Copyright © 2021 NetApp Inc. All rights reserved.

## Overview

Displays DNS information and controls the DNS subsytem. DNS domain name and DNS servers are required parameters.

## Retrieving DNS information

The DNS GET endpoint retrieves all of the DNS configurations for all SVMs. DNS configuration for the cluster is retrieved via `/api/cluster`.

## Examples

### Retrieving all of the fields for all of the DNS configurations

    from netapp_ontap import HostConnection
    from netapp_ontap.resources import Dns

    with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
        print(list(Dns.get_collection(fields="*")))

## Deleting a DNS configuration

The DNS DELETE endpoint deletes the DNS configuration for the specified SVM.

## Example

The following example shows a DELETE operation.

    from netapp_ontap import HostConnection
    from netapp_ontap.resources import Dns

    with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
        resource = Dns(**{"svm.uuid": "179d3c85-7053-11e8-b9b8-005056b41bd1"})
        resource.delete()

## Classes

`class Dns (*args, **kwargs)`

  Allows interaction with Dns objects on the host

  Initialize the instance of the resource.

  Any keyword arguments are set on the instance as properties. For example, if the class was named 'MyResource', then this statement would be true:

      MyResource(name='foo').name == 'foo'

  ## Args

  `*args`
    Each positional argument represents a parent key as used in the URL of the object. That is, each value will be used to fill in a segment of the URL which refers to some parent object. The order of these arguments must match the order they are specified in the URL, from left to right.
  `**kwargs`
    each entry will have its key set as an attribute name on the instance and its value will be the value of that attribute.

  ### Ancestors

  - Resource

  ### Static methods

  `def count_collection(*args, connection: HostConnection = None, **kwargs) -> int`

    Retrieves the DNS configurations of all SVMs. Specify 'scope' as 'svm' to retrieve the DNS configuration of all the data SVMs. Specify 'scope' as 'cluster' to retrieve the DNS configuration of the cluster.

    ### Advanced properties

    - 'tld_query_enabled'
    - 'source_address_match'
    - 'packet_query_match'
    - 'status' property retrieves the status of each name server of the DNS configuration for an SVM.

    ### Related ONTAP commands

    - `vserver services name-service dns show`
    - `vserver services name-service dns check`
    - `vserver services name-service dns dynamic-update show`

    ### Learn more

    - `DOC /name-services/dns`

    Fetch a count of all objects of this type from the host.

    This calls GET on the object to determine the number of records. It is more efficient than calling get_collection() because it will not construct any objects. Query parameters can be passed in as kwargs to determine a count of objects that match some filtered criteria.

    ## Args

    `*args`
      Each entry represents a parent key which is used to build the path to the child object. If the URL definition were /api/foos/{foo.name}/bars, then to get the count of bars for a particular foo, the foo.name value should be passed.
    `connection`
      The `HostConnection` object to use for this API call. If unset, tries to use the connection which is set globally for the library or from the current context.
    `**kwargs`
      Any key/value pairs passed will be sent as query parameters to the host. These query parameters can affect the count. A return_records query param will be ignored.

    ## Returns

    On success, returns an integer count of the objects of this type. On failure, returns -1.

    ## Raises

    `NetAppRestError`: If the API call returned a status code >= 400, or if there is no connection available to use either passed in or on the library.

  `def delete_collection(*args, body: typing.Union = None, connection: HostConnection = None, **kwargs) -> NetAppResponse`

    Deletes DNS domain configuration of the specified SVM.

    ### Related ONTAP commands

    - `vserver services name-service dns delete`

    ### Learn more

    - `DOC /name-services/dns`

    Delete all objects in a collection which match the given query.

    All records on the host which match the query will be deleted.

    ## Args

    `*args`
      Each entry represents a parent key which is used to build the path to the child object. If the URL definition were /api/foos/{foo.name}/bars, then to delete the collection of bars for a particular foo, the foo.name value should be passed.
    `body`
      The body of the delete request. This could be a Resource instance or a dictionary object.
    `connection`
      The `HostConnection` object to use for this API call. If unset, tries to use the connection which is set globally for the library or from the current context.
    `**kwargs`
      Any key/value pairs passed will be sent as query parameters to the host. Only resources matching this query will be deleted.

    ## Returns

    A `NetAppResponse` object containing the details of the HTTP response.

    ## Raises

    `NetAppRestError`: If the API call returned a status code >= 400

  `def find(*args, connection: HostConnection = None, **kwargs) -> Resource`

    Retrieves the DNS configurations of all SVMs. Specify 'scope' as 'svm' to retrieve the DNS configuration of all the data SVMs. Specify 'scope' as 'cluster' to retrieve the DNS configuration of the cluster.

    ### Advanced properties

    - 'tld_query_enabled'
    - 'source_address_match'
    - 'packet_query_match'
    - 'status' property retrieves the status of each name server of the DNS configuration for an SVM.

    ### Related ONTAP commands

    - `vserver services name-service dns show`
    - `vserver services name-service dns check`
    - `vserver services name-service dns dynamic-update show`

    ### Learn more

    - `DOC /name-services/dns`

    Find an instance of an object on the host given a query.

    The host will be queried with the provided key/value pairs to find a matching resource. If 0 are found, None will be returned. If more than 1 is found, an error will be raised or returned. If there is exactly 1 matching record, then it will be returned.

    ## Args

    `*args`
      Each entry represents a parent key which is used to build the path to the child object. If the URL definition were /api/foos/{foo.name}/bars, then to find a bar for a particular foo, the foo.name value should be passed.
    `connection`
      The `HostConnection` object to use for this API call. If unset, tries to use the connection which is set globally for the library or from the current context.
    `**kwargs`
      Any key/value pairs passed will be sent as query parameters to the host.

    ## Returns

    - `DOC /name-services/dns`

    Fetch a list of all objects of this type from the host.

    This is a lazy fetch, making API calls only as necessary when the result of this call is iterated over. For instance, if max_records is set to 5, then iterating over the collection causes an API call to be sent to the server once for every 5 records. If the client stops iterating before getting to the 6th record, then no additional API calls are made.

    ## Args

    `*args`
      Each entry represents a parent key which is used to build the path to the child object. If the URL definition were /api/foos/{foo.name}/bars, then to get the collection of bars for a particular foo, the foo.name value should be passed.
    `connection`
      The `HostConnection` object to use for this API call. If unset, tries to use the connection which is set globally for the library or from the current context.
    `max_records`
      The maximum number of records to return per call
    `**kwargs`
      Any key/value pairs passed will be sent as query parameters to the host.

    ## Returns

    A list of `Resource` objects

    ## Raises

    `NetAppRestError`: If there is no connection available to use either passed in or on the library. This would be not be raised when get_collection() is called, but rather when the result is iterated.

  `def patch_collection(body: dict, *args, connection: HostConnection = None, **kwargs) -> NetAppResponse`

    Updates DNS domain and server configurations of an SVM.

    ### Important notes

    - Both DNS domains and servers can be modified.
    - The domains and servers fields cannot be empty.
    - IPv6 must be enabled if IPv6 family addresses are specified for the `servers` field.
    - The DNS server specified using the `servers` field is validated during this operation.
      The validation fails in the following scenarios:
    - The server is not a DNS server.
    - The server does not exist.
    - The server is unreachable.
    - The DNS server validation can be skipped by setting the property "skip_config_validation" to "true".
    - Dynamic DNS configuration can be modified.
    - If both DNS and Dynamic DNS parameters are modified, DNS parameters are updated first followed by Dynamic DNS parameters. If updating Dynamic DNS fails, then the updated DNS configuration is not reverted.

    #### The following parameters are optional:

    - timeout
    - attempts
    - source_address_match
    - packet_query_match
