Network.AWS.ECS.UpdateService
Description
Modify the desired count or task definition used in a service.
You can add to or subtract from the number of instantiations of a task
definition in a service by specifying the cluster that the service is running
in and a new desiredCount parameter.
You can use UpdateService to modify your task definition and deploy a new
version of your service, one task at a time. If you modify the task
definition with UpdateService, Amazon ECS spawns a task with the new version
of the task definition and then stops an old task after the new version is
running. Because UpdateService starts a new version of the task before
stopping an old version, your cluster must have capacity to support one more
instantiation of the task when UpdateService is run. If your cluster cannot
support another instantiation of the task used in your service, you can
reduce the desired count of your service by one before modifying the task
definition.

Arguments
| :: Text | |
| -> UpdateService |
UpdateService constructor.
The fields accessible through corresponding lenses are:
Request lenses
usCluster :: Lens' UpdateService (Maybe Text) Source
The short name or full Amazon Resource Name (ARN) of the cluster that your service is running on. If you do not specify a cluster, the default cluster is assumed.
usDesiredCount :: Lens' UpdateService (Maybe Int) Source
The number of instantiations of the task that you would like to place and keep running in your service.
usService :: Lens' UpdateService Text Source
The name of the service that you want to update.
usTaskDefinition :: Lens' UpdateService (Maybe Text) Source
The family and revision ('family:revision') or full Amazon Resource Name (ARN)
of the task definition that you want to run in your service. If you modify
the task definition with UpdateService, Amazon ECS spawns a task with the new
version of the task definition and then stops an old task after the new
version is running.
Response
Response constructor
updateServiceResponse :: UpdateServiceResponse Source
UpdateServiceResponse constructor.
The fields accessible through corresponding lenses are:
Response lenses
usrService :: Lens' UpdateServiceResponse (Maybe ContainerService) Source
The full description of your service following the update call.
