aws servicediscovery discover-instances
Discovers registered instances for a specified namespace and service. You can use DiscoverInstances to discover instances for any type of namespace. For public and private DNS namespaces, you can also use DNS queries to discover instances
Options
| Name | Description |
|---|---|
--namespace-name <string> | The name of the namespace that you specified when you registered the instance |
--service-name <string> | The name of the service that you specified when you registered the instance |
--max-results <integer> | The maximum number of instances that you want AWS Cloud Map to return in the response to a DiscoverInstances request. If you don't specify a value for MaxResults, AWS Cloud Map returns up to 100 instances |
--query-parameters <map> | Filters to scope the results based on custom attributes for the instance. For example, {version=v1, az=1a}. Only instances that match all the specified key-value pairs will be returned |
--optional-parameters <map> | Opportunistic filters to scope the results based on custom attributes. If there are instances that match both the filters specified in both the QueryParameters parameter and this parameter, they are returned. Otherwise, these filters are ignored and only instances that match the filters specified in the QueryParameters parameter are returned |
--health-status <string> | The health status of the instances that you want to discover |
--cli-input-json <string> | Performs service operation based on the JSON string provided. The JSON string follows the format provided by ``--generate-cli-skeleton``. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally |
--generate-cli-skeleton <string> | Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value ``input``, prints a sample input JSON that can be used as an argument for ``--cli-input-json``. If provided with the value ``output``, it validates the command inputs and returns a sample output JSON for that command |
