Create Service

  • Article

Creates the specified Service Fabric service.

This api allows creating a new Service Fabric stateless or stateful service under a specified Service Fabric application. The description for creating the service includes partitioning information and optional properties for placement and load balancing. Some of the properties can later be modified using UpdateService API.

POST /Applications/{applicationId}/$/GetServices/$/Create?api-version=6.0&timeout={timeout}

Parameters

Name Type Required Location
applicationId string Yes Path
api-version string Yes Query
timeout integer (int64) No Query
ServiceDescription ServiceDescription Yes Body

applicationId

Type: string
Required: Yes

The identity of the application. This is typically the full name of the application without the 'fabric:' URI scheme. Starting from version 6.0, hierarchical names are delimited with the "~" character. For example, if the application name is "fabric:/myapp/app1", the application identity would be "myapp~app1" in 6.0+ and "myapp/app1" in previous versions.

api-version

Type: string
Required: Yes
Default: 6.0

The version of the API. This parameter is required and its value must be '6.0'.

Service Fabric REST API version is based on the runtime version in which the API was introduced or was changed. Service Fabric runtime supports more than one version of the API. This is the latest supported version of the API. If a lower API version is passed, the returned response may be different from the one documented in this specification.

Additionally the runtime accept any version that is higher than the latest supported version up to the current version of the runtime. So if the latest API version is 6.0, but if the runtime is 6.1, in order to make it easier to write the clients, the runtime will accept version 6.1 for that API. However the behavior of the API will be as per the documented 6.0 version.

timeout

Type: integer (int64)
Required: No
Default: 60
InclusiveMaximum: 4294967295
InclusiveMinimum: 1

The server timeout for performing the operation in seconds. This timeout specifies the time duration that the client is willing to wait for the requested operation to complete. The default value for this parameter is 60 seconds.

ServiceDescription

Type: ServiceDescription
Required: Yes

The information necessary to create a service.
