Request Parameters
For information about the parameters that are common to all actions, see Common Parameters.
The request accepts the following data in JSON format.
- cluster
-
The short name or full Amazon Resource Name (ARN) of the cluster to use when filtering the
ListServices
results. If you do not specify a cluster, the default cluster is assumed.Type: String
Required: No
- launchType
-
The launch type to use when filtering the
ListServices
results.Type: String
Valid Values:
EC2 | FARGATE | EXTERNAL
Required: No
- maxResults
-
The maximum number of service results that
ListServices
returned in paginated output. When this parameter is used,ListServices
only returnsmaxResults
results in a single page along with anextToken
response element. The remaining results of the initial request can be seen by sending anotherListServices
request with the returnednextToken
value. This value can be between 1 and 100. If this parameter isn't used, thenListServices
returns up to 10 results and anextToken
value if applicable.Type: Integer
Required: No
- nextToken
-
The
nextToken
value returned from aListServices
request indicating that more results are available to fulfill the request and further calls will be needed. IfmaxResults
was provided, it is possible the number of results to be fewer thanmaxResults
.Note
This token should be treated as an opaque identifier that is only used to retrieve the next items in a list and not for other programmatic purposes.
Type: String
Required: No
- schedulingStrategy
-
The scheduling strategy to use when filtering the
ListServices
results.Type: String
Valid Values:
REPLICA | DAEMON

"nextToken": "string",
"serviceArns": [ "string" ]
}
Response Elements
If the action is successful, the service sends back an HTTP 200 response.
The following data is returned in JSON format by the service.
- nextToken
-
The
nextToken
value to include in a futureListServices
request. When the results of aListServices
request exceedmaxResults
, this value can be used to retrieve the next page of results. This value isnull
when there are no more results to return.Type: String
- serviceArns
-
The list of full ARN entries for each service that's associated with the specified cluster.
Type: Array of strings
Errors
For information about the errors that are common to all actions, see Common Errors.
- ClientException
-
These errors are usually caused by a client action. This client action might be using an action or resource on behalf of a user that doesn't have permissions to use the action or resource. Or, it might be specifying an identifier that isn't valid.
The following list includes additional causes for the error:
-
The
RunTask
could not be processed because you use managed scaling and there is a capacity error because the quota of tasks in thePROVISIONING
per cluster has been reached. For information about the service quotas, see Amazon ECS service quotas.
