Discovers registered instances for a specified namespace and service

Description

Discovers registered instances for a specified namespace and service. You can use discover_instances to discover instances for any type of namespace. discover_instances 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.

See https://www.paws-r-sdk.com/docs/servicediscovery_discover_instances/ for full documentation.

Usage

servicediscovery_discover_instances(
  NamespaceName,
  ServiceName,
  MaxResults = NULL,
  QueryParameters = NULL,
  OptionalParameters = NULL,
  HealthStatus = NULL
)

Arguments

`NamespaceName`	[required] The `HttpName` name of the namespace. It's 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.
`ServiceName`	[required] The name of the service that you specified when you registered the instance.
`MaxResults`	The maximum number of instances that you want Cloud Map to return in the response to a `discover_instances` request. If you don't specify a value for `MaxResults`, Cloud Map returns up to 100 instances.
`QueryParameters`	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.
`OptionalParameters`	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.
`HealthStatus`	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.
