            }
        },
    }
)

Creating a DNS configuration

The DNS POST endpoint creates a DNS configuration for the specified SVM.

Example

The following example shows a POST operation:

from netapp_ontap import HostConnection
from netapp_ontap.resources import Dns

with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
    resource = Dns()
    resource.svm.uuid = "179d3c85-7053-11e8-b9b8-005056b41bd1"
    resource.domains = ["domainA.example.com"]
    resource.servers = ["10.10.10.10"]
    resource.post(hydrate=True)
    print(resource)

Updating a DNS configuration

The DNS PATCH endpoint updates the DNS configuration for the specified SVM.

Examples

Updating both the DNS domains and servers

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.domains = ["domainA.example.com", "domainB.example.com"]
    resource.servers = ["10.10.10.10", "10.10.10.11"]
    resource.patch()

Updating the DNS servers only

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.servers = ["10.10.10.10"]
    resource.patch()

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

Static methods

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

Retrieves the DNS configurations of all data SVMs. DNS configuration for the cluster is retrieved and managed via /api/cluster.

  • vserver services name-service dns show
  • vserver services name-service dns check

Learn more


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.

  • vserver services name-service dns delete

Learn more


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 patched.

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 data SVMs. DNS configuration for the cluster is retrieved and managed via /api/cluster.

  • vserver services name-service dns show
  • vserver services name-service dns check

Learn more


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

A Resource object containing the details of the object or None if no matches were found.

Raises

NetAppRestError: If the API call returned more than 1 matching resource.

def get_collection(*args, connection: HostConnection = None, max_records: int = None, **kwargs) -> typing.Iterable

Retrieves the DNS configurations of all data SVMs. DNS configuration for the cluster is retrieved and managed via /api/cluster.

  • vserver services name-service dns show
  • vserver services name-service dns check

Learn more


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.

All records on the host which match the query will be patched with the provided body.

Args

body
A dictionary of name/value pairs to set on all matching members of the collection.
*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 patch 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.
**kwargs
Any key/value pairs passed will be sent as query parameters to the host. Only resources matching this query will be patched.

Returns

A NetAppResponse object containing the details of the HTTP response.
