Module netapp_ontap.resources.dns
Copyright © 2020 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 data 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="*")))

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"})

},
}
)
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.

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
-

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

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.

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
objectsRaises
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.

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.

Args
hydrate
- If set to True, after the response is received from the call, a a GET call will be made to refresh all fields of the object.
