Synopsis

Calls the AWS Cloud Map DiscoverInstances API operation.

Syntax

Find-SDInstance
-ServiceName <String>
-HealthStatus <HealthStatusFilter>
-NamespaceName <String>
-OptionalParameter <Hashtable>
-OwnerAccount <String>
-QueryParameter <Hashtable>
-MaxResult <Int32>
-Select <String>
-ClientConfig <AmazonServiceDiscoveryConfig>

Description

Discovers registered instances for a specified namespace and service. You can use DiscoverInstances to discover instances for any type of namespace. DiscoverInstances returns a randomized list of instances allowing customers to distribute traffic evenly across instances. For public and private DNS namespaces, you can also use DNS queries to discover instances.

Parameters

-ClientConfig <AmazonServiceDiscoveryConfig>
Amazon.PowerShell.Cmdlets.SD.AmazonServiceDiscoveryClientCmdlet.ClientConfig
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-HealthStatus <HealthStatusFilter>
The health status of the instances that you want to discover. This parameter is ignored for services that don't have a health check configured, and all instances are returned.
HEALTHY
Returns healthy instances.
UNHEALTHY
Returns unhealthy instances.
ALL
Returns all instances.
HEALTHY_OR_ELSE_ALL
Returns healthy instances, unless none are reporting a healthy state. In that case, return all instances. This is also called failing open.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-MaxResult <Int32>
The maximum number of instances that you want Cloud Map to return in the response to a DiscoverInstances request. If you don't specify a value for MaxResults, Cloud Map returns up to 100 instances.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesMaxResults
-NamespaceName <String>
The HttpName name of the namespace. The HttpName is found in the HttpProperties member of the Properties member of the namespace. In most cases, Name and HttpName match. However, if you reuse Name for namespace creation, a generated hash is added to HttpName to distinguish the two.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-OptionalParameter <Hashtable>
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, all of these instances are returned. Otherwise, the filters are ignored, and only instances that match the filters that are specified in the QueryParameters parameter are returned. Starting with version 4 of the SDK this property will default to null. If no data for this property is returned from the service the property will also be null. This was changed to improve performance and allow the SDK and caller to distinguish between a property not set or a property being empty to clear out a value. To retain the previous SDK behavior set the AWSConfigs.InitializeCollections static property to true.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesOptionalParameters
-OwnerAccount <String>
The ID of the Amazon Web Services account that owns the namespace associated with the instance, as specified in the namespace ResourceOwner field. For instances associated with namespaces that are shared with your account, you must specify an OwnerAccount.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-QueryParameter <Hashtable>
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 are returned. Starting with version 4 of the SDK this property will default to null. If no data for this property is returned from the service the property will also be null. This was changed to improve performance and allow the SDK and caller to distinguish between a property not set or a property being empty to clear out a value. To retain the previous SDK behavior set the AWSConfigs.InitializeCollections static property to true.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesQueryParameters
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'Instances'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.ServiceDiscovery.Model.DiscoverInstancesResponse). Specifying the name of a property of type Amazon.ServiceDiscovery.Model.DiscoverInstancesResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-ServiceName <String>
The name of the service that you specified when you registered the instance.
Required?True
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAK
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-EndpointUrl <String>
The endpoint to make the call against.Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-ProfileLocation <String>
Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials.If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAWSProfilesLocation, ProfilesLocation
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesStoredCredentials, AWSProfileName
-Region <Object>
The system name of an AWS region or an AWSRegion instance. This governs the endpoint that will be used when calling service operations. Note that the AWS resources referenced in a call are usually region-specific.
Required?False

Outputs

Amazon.ServiceDiscovery.Model.HttpInstanceSummary or Amazon.ServiceDiscovery.Model.DiscoverInstancesResponse
This cmdlet returns a collection of Amazon.ServiceDiscovery.Model.HttpInstanceSummary objects. The service call response (type Amazon.ServiceDiscovery.Model.DiscoverInstancesResponse) can be returned by specifying '-Select *'.
