# Use CloudFormation to create a sample AWS PCS cluster
<a name="get-started-cfn-create"></a>

The following procedure uses a CloudFormation template in the AWS Management Console to create a sample AWS PCS cluster. For more information about CloudFormation, see [What is CloudFormation?](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/Welcome.html) in the *AWS CloudFormation User Guide*. For more information about AWS PCS resource types in CloudFormation, see [AWS PCS resource type reference](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/AWS_PCS.html) in the *AWS CloudFormation User Guide*.

1. Under **Provide a stack name**, enter a descriptive name. This is the name for your CloudFormation stack. The template uses this value as the name for your AWS PCS cluster.

1. Under **Parameters**:

   1. Under **SlurmVersion**, choose the version of Slurm you want your cluster to use.

   1. Under **NodeArchitecture**, choose **x86** to deploy a cluster that uses x86\$164-compatible instances, or choose **Graviton** to use Arm64 instances.

   1. For **KeyName**, choose an SSH key pair to access the cluster login nodes. Make sure that you have the PEM file for the key pair that you choose.

   1. For **ClientIpCidr**, enter an IP range in CIDR format to control access to the login nodes.
**Warning**  
 The default value of `0.0.0.0/0` allows access from all IP addresses.

   1. Leave the values for **HpcRecipesS3Bucket** and **HpcRecipesBranch** as their default values.

1. Under **Capabilities and transforms**:

   1. Select the checkbox to acknowledge that CloudFormation will create IAM resources.

   1. Select the checkbox to acknowledge that CloudFormation will create IAM resources with custom names.

   1. Select the checkbox to acknowledge `CAPABILITY_AUTO_EXPAND` for the new stack. For more information, see [CreateStack](https://docs.aws.amazon.com/AWSCloudFormation/latest/APIReference/API_CreateStack.html#API_CreateStack_RequestParameters) in the *AWS CloudFormation API Reference*.

1. Choose **Create stack**.

1. Monitor the status of your stack. You can connect to the cluster after the status of the stack is `CREATE_COMPLETE`.
