Step 3: Add resource collections

This section discusses the following options that you can use to form the basis of your application structure:

Add resource collections

This section discusses the following methods that you use to form the basis of your application structure:

Using AWS CloudFormation stacks

Choose the AWS CloudFormation stacks that contain the resources you want to use in the application you're describing. The stacks can be from the AWS account that you are using to describe the application, or they can be from different accounts or different Regions.

To discover the resources that form the basis of your application structure

  1. Select CloudFormation stack to discover your stack-based resources.

  2. Choose stacks from the Choose stacks dropdown list that are associated with your AWS account and Region.

    To use stacks that are in a different AWS account, different Region, or both, choose the right arrow adjacent to Add stack outside of AWS Region and enter the Amazon Resource Name (ARN) of the stack in the Enter a stack ARN box, and then choose Add stack ARN. For more information about ARNs, see Amazon Resource Names (ARNs) in the AWS General Reference.

Using AWS Resource Groups

Choose the AWS Resource Groups that contain the resources that you want to use in the application that you're describing.

To discover the resources that form the basis of your application structure

  1. Select Resource groups to discover the AWS Resource Groups that contain the resources.

  2. Choose resources from Choose a resource group dropdown list.

    To use AWS Resource Groups that are in a different AWS account, different Region, or both, choose the right arrow adjacent to Resource Group ARN: and enter the Amazon Resource Name (ARN) of the AWS Resource Groups in the Enter a resource group ARN box, and then choose Add resource Group ARN. For more information about ARNs, see Amazon Resource Names (ARNs) in the AWS General Reference.

Using myApplications applications

Choose the myApplications application you want to include in AWS Resilience Hub

To include myApplications application in AWS Resilience Hub

  1. Select myApplications.

  2. Choose an application from the Select application dropdown list.

Using Terraform state files

Choose the Terraform state file that contains your Amazon S3 bucket resources that you want to use in the application you're describing. You can navigate to the location of your Terraform state file or provide a link to a Terraform state file you have access to that’s located in a different Region.

Note

AWS Resilience Hub supports Terraform state file version 0.12 and later.

To discover the resources that form the basis of your application structure

  1. Select Terraform state files to discover your S3 bucket resources.

  2. From the Select state files:: section, choose Browse S3 to navigate to the location of your Terraform state file.

    To use Terraform state files located in a different Region, provide the link to the location of Terraform state file in the S3 URI field, and choose Add S3 URL.

    The limit for Terraform state files is 4 megabytes (MB).

  3. From Choose an archive in S3 dialog box, select your Amazon Simple Storage Service bucket from the Buckets section.

  4. From the Objects section, select a key, and choose Choose.

Add EKS clusters

This section discusses about using Amazon EKS clusters to form the basis of your application structure.

Note

You must have Amazon EKS permissions and additional IAM roles to connect to the Amazon EKS cluster. For more information about adding single account and cross-account Amazon EKS permissions and additional IAM roles to connect to the cluster, see the following topics:

Choose the Amazon EKS clusters and namespaces that contain the resources you want to use in the application you're describing. The Amazon EKS clusters can be from the AWS account that you are using to describe the application, or they can be from different accounts or different Regions.

Note

For AWS Resilience Hub to assess your Amazon EKS clusters, you must manually add the relevant namespaces to each of the Amazon EKS clusters in EKS clusters and namespaces section. The namespace name must match exactly with the namespace name on your Amazon EKS clusters.

To add Amazon EKS clusters

  1. In 1. Select EKS clusters section, choose the Amazon EKS clusters from the Choose EKS clusters dropdown list that are associated with your AWS account and Region.

  2. To use Amazon EKS clusters that are in a different AWS account, different Region, or both, choose the right arrow adjacent to Add an EKS cluster within a different account or Region and enter the Amazon Resource Name (ARN) of the Amazon EKS cluster in the Enter an EKS ARN box, and then choose Add EKS ARN. For more information about ARNs, see Amazon Resource Names (ARNs) in the AWS General Reference.

    For more information about adding permissions to access cross-Region Amazon Elastic Kubernetes Service clusters, see Enabling AWS Resilience Hub access to your Amazon Elastic Kubernetes Service cluster.

To add namespaces from the selected Amazon EKS clusters

  1. In the Add namespaces section, from the EKS clusters and namespaces table, select the radio button located at the left of Amazon EKS cluster name, and then choose Update namespaces.

    You can identify Amazon EKS clusters by the following:

    • EKS cluster name – Indicates the name of the selected Amazon EKS clusters.

    • # of Namespaces – Indicates the number of namespaces selected in the Amazon EKS clusters.

    • Status – Indicates whether AWS Resilience Hub has included the namespaces from the selected Amazon EKS clusters in your application. You can identify the status using the following options:

      • Namespace required – Indicates that you have not included any namespaces from the Amazon EKS cluster.

      • Namespaces added – Indicates that you have included one or more namespaces from the Amazon EKS cluster.

  2. To add a namespace, in the Update namespaces dialog box, choose Add a new namespace.

    The Update namespaces dialog box displays all the namespaces that you have selected from your Amazon EKS cluster, as an editable option.

  3. In the Update namespaces dialog box, you have the following edit options:

    • To add a new namespace, choose Add a new namespace, and then enter the namespace name in namespace box.

      The namespace name must exactly match with the namespace name on your Amazon EKS cluster.

    • To remove a namespace, choose Remove located next to the namespace.

    • To apply the selected namespaces to all the Amazon EKS clusters, choose Apply namespaces to all EKS clusters.

      If you choose this option, your previous namespace selection in the other Amazon EKS clusters will be overridden with the current namespace selection.

  4. To include the updated namespaces in your application, choose Update.
