Creates an Amazon ECS cluster"

long_description "### Description

#### Amazon ECS

Amazon EC2 Container Service (ECS) is a highly scalable, high performance container management service that supports Docker containers and allows you to easily run applications on a managed cluster of Amazon EC2 instances.

#### This CloudApp

RightScale's Self-Service integration for Amazon ECS makes it easy to launch and scale a dynamically-sized ECS cluster, and exposes Docker runtime and monitoring data within RightScale's Container Manager.

---

### Parameters

#### Node Count

Enter the number of nodes for the cluster.

---

### Outputs

#### Launch Container Manager

Click this link to launch RightScale's Container Manager. Documentation for using this dashboard to view Docker runtime and monitoring data can be found at [http://docs.rightscale.com/cm/dashboard/manage/containers/index.html](http://docs.rightscale.com/cm/dashboard/manage/containers/index.html)

### Actions

#### Resize Cluster

This action will update the target number of cluster nodes. Although the action completes right away, please wait a few minutes for the requested changes to happen in the background.
