describe_nat_gateways(**kwargs)¶

Describes one or more of your NAT gateways.

Request Syntax

response = client.describe_nat_gateways(
    DryRun=True|False,
    Filters=[
        {
            'Name': 'string',
            'Values': [
                'string',
            ]
        },
    ],
    MaxResults=123,
    NatGatewayIds=[
        'string',
    ],
    NextToken='string'
)

Parameters

DryRun (boolean) -- Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation . Otherwise, it is UnauthorizedOperation .
Filters (list) --
One or more filters.
- nat-gateway-id - The ID of the NAT gateway.
- state - The state of the NAT gateway ( pending | failed | available | deleting | deleted ).
- subnet-id - The ID of the subnet in which the NAT gateway resides.
- tag :<key> - The key/value combination of a tag assigned to the resource. Use the tag key in the filter name and the tag value as the filter value. For example, to find all resources that have a tag with the key Owner and the value TeamA , specify tag:Owner for the filter name and TeamA for the filter value.
- tag-key - The key of a tag assigned to the resource. Use this filter to find all resources assigned a tag with a specific key, regardless of the tag value.
- vpc-id - The ID of the VPC in which the NAT gateway resides.
- (dict) --
  A filter name and value pair that is used to return a more specific list of results from a describe operation. Filters can be used to match a set of resources by specific criteria, such as tags, attributes, or IDs.
  
  If you specify multiple filters, the filters are joined with an AND , and the request returns only results that match all of the specified filters.
  - Name (string) --
    The name of the filter. Filter names are case-sensitive.
  - Values (list) --
    The filter values. Filter values are case-sensitive. If you specify multiple values for a filter, the values are joined with an OR , and the request returns all results that match any of the specified values.
    - (string) --
MaxResults (integer) -- The maximum number of items to return for this request. To get the next page of items, make another request with the token returned in the output. For more information, see Pagination.
NatGatewayIds (list) --
One or more NAT gateway IDs.
- (string) --
NextToken (string) -- The token returned from a previous paginated request. Pagination continues from the end of the items returned by the previous request.
