Creating a cluster - Amazon ECS
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China.

Creating a cluster

You can create an Amazon ECS cluster using the Amazon Web Services Management Console, as described in this topic. Before you begin, be sure that you've completed the steps in Setting up with Amazon ECS.

The console cluster creation wizard provides a simple way to create the resources that are needed by an Amazon ECS cluster by creating a Amazon CloudFormation stack. It also lets you customize several common cluster configuration options. However, the wizard does not allow you to customize every resource option. If your requirements extend beyond what is supported in this wizard, consider using our reference architecture at https://github.com/awslabs/ecs-refarch-cloudformation.

If you add or modify the underlying cluster resources directly after they are created by the wizard you may receive an error when attempting to delete the cluster. Amazon CloudFormation refers to this as stack drift. For more information on detecting drift on an existing Amazon CloudFormation stack, see Detect Drift on an Entire CloudFormation Stack in the Amazon CloudFormation User Guide.
