Perform the following steps once you have created a security group and a VPC with at least one subnet:
- Navigate to https://console.aws.amazon.com/ecs and click on Create Cluster button.
- Choose the Networking Only (Powered by AWS Fargate) template and then click Next Step.
- Enter the name of the cluster, for example, pets-cluster, and leave the Create VPC checkbox unchecked.
- Click Create. The cluster will be created for you.
This might take a moment or so. Once done, you can click View Cluster button.
