If the number of tasks running in * a service drops below <code>desiredCount</code>, Amazon ECS spawns another copy of the task in the specified * cluster. To update an existing service, see <a>UpdateService</a>. * </p> * <p> * In addition to maintaining the desired count of tasks in your service, you can optionally run your service behind * a load balancer. The load balancer distributes traffic across the tasks that are associated with the service. For * more information, see <a * href="http://docs.aws.amazon.com/AmazonECS/latest/developerguide/service-load-balancing.html">Service Load * Balancing</a> in the <i>Amazon EC2 Container Service Developer Guide</i>. * </p> * <p> * You can optionally specify a deployment configuration for your service. During a deployment (which is triggered * by changing the task definition or the desired count of a service with an <a>UpdateService</a> operation), the * service scheduler uses the <code>minimumHealthyPercent</code> and <code>maximumPercent</code> parameters to * determine the deployment strategy. * </p> * <p> * The <code>minimumHealthyPercent</code> represents a lower limit on the number of your service's tasks that must * remain in the <code>RUNNING</code> state during a deployment, as a percentage of the <code>desiredCount</code> * (rounded up to the nearest integer). This parameter enables you to deploy without using additional cluster * capacity. For example, if your service has a <code>desiredCount</code> of four tasks and a * <code>minimumHealthyPercent</code> of 50%, the scheduler can stop two existing tasks to free up cluster capacity * before starting two new tasks. Tasks for services that <i>do not</i> use a load balancer are considered healthy * if they are in the <code>RUNNING</code> state. Tasks for services that <i>do</i> use a load balancer are * considered healthy if they are in the <code>RUNNING</code> state and the container instance they are hosted on is * reported as healthy by the load balancer. The default value for <code>minimumHealthyPercent</code> is 50% in the * console and 100% for the AWS CLI, the AWS SDKs, and the APIs. * </p> * <p> * The <code>maximumPercent</code> parameter represents an upper limit on the number of your service's tasks that * are allowed in the <code>RUNNING</code> or <code>PENDING</code> state during a deployment, as a percentage of the * <code>desiredCount</code> (rounded down to the nearest integer). This parameter enables you to define the * deployment batch size. For example, if your service has a <code>desiredCount</code> of four tasks and a * <code>maximumPercent</code> value of 200%, the scheduler can start four new tasks before stopping the four older * tasks (provided that the cluster resources required to do this are available). The default value for * <code>maximumPercent</code> is 200%. * </p> * <p> * When the service scheduler launches new tasks, it determines task placement in your cluster using the following * logic: * </p> * <ul> * <li> * <p> * Determine which of the container instances in your cluster can support your service's task definition (for * example, they have the required CPU, memory, ports, and container instance attributes). * </p> * </li> * <li> * <p> * By default, the service scheduler attempts to balance tasks across Availability Zones in this manner (although * you can choose a different placement strategy) with the <code>placementStrategy</code> parameter): * </p> * <ul> * <li> * <p> * Sort the valid container instances by the fewest number of running tasks for this service in the same * Availability Zone as the instance. For example, if zone A has one running service task and zones B and C each * have zero, valid container instances in either zone B or C are considered optimal for placement. * </p> * </li> * <li> * <p> * Place the new service task on a valid container instance in an optimal Availability Zone (based on the previous * steps), favoring container instances with the fewest number of running tasks for this service. * </p> * </li> * </ul> * </li> * </ul> * * @param createServiceRequest * @return Result of the CreateService operation returned by the service. * @throws ServerException * These errors are usually caused by a server issue. * @throws ClientException * These errors are usually caused by a client action, such as using an action or resource on behalf of a * user that doesn't have permission to use the action or resource, or specifying an identifier that is not * valid. * @throws InvalidParameterException * The specified parameter is invalid.
