Step 5: (Optional) Cleanup

Follow these steps to remove all the resources created in this tutorial.

Remove the resources created in this tutorial

  1. Delete your deployment. You can use the following command to do so.

    kubectl delete deployment my-keyspaces-app -n my-eks-namespace

  2. Delete the Amazon EKS cluster and all Pods contained in it. This also deletes related resources like the service account and OIDC identity provider. You can use the following command to do so.

    eksctl delete cluster --name my-eks-cluster --region aws-region

  3. Delete the IAM role used for the Amazon EKS service account with access permissions to Amazon Keyspaces. First, you have to remove the managed policy that is attached to the role.

    aws iam detach-role-policy --role-name my-iam-role --policy-arn arn:aws:iam::aws:policy/AmazonKeyspacesFullAccess

    Then you can delete the role using the following command.

    aws iam delete-role --role-name my-iam-role

    For more information, see Deleting an IAM role (Amazon CLI) in the IAM User Guide.

  4. Delete the Amazon ECR repository including all the images stored in it. You can do so using the following command.

    aws ecr delete-repository \
      --repository-name my-ecr-repository \
      --force \
      --region aws-region

    Note that the force flag is required to delete a repository that contains images. To delete your image first, you can do so using the following command. 

    aws ecr batch-delete-image \
      --repository-name my-ecr-repository \
      --image-ids imageTag=latest \
      --region aws-region

    For more information, see Delete an image in the Amazon Elastic Container Registry User Guide.

  5. Delete the Amazon Keyspaces keyspace and table. Deleting the keyspace automatically deletes all tables in that keyspace. You can use one the following options to do so.

    Amazon CLI
    aws keyspaces delete-keyspace --keyspace-name 'aws'

    To confirm that the keyspace was deleted, you can use the following command.

    aws keyspaces list-keyspaces

    To delete the table first, you can use the following command.

    aws keyspaces delete-table --keyspace-name 'aws' --table-name 'user'

    To confirm that your table was deleted, you can use the following command.

    aws keyspaces list-tables --keyspace-name 'aws'

    For more information, see delete keyspace and delete table in the Amazon CLI Command Reference.

    cqlsh
    DROP KEYSPACE IF EXISTS "aws";

    To verify that your keyspaces was deleted, you can use the following statement.

    SELECT * FROM system_schema.keyspaces ;

    Your keyspace should not be listed in the output of this statement. Note that there can be a delay until the keyspaces is deleted. For more information, see DROP KEYSPACE.

    To delete the table first, you can use the following command.

    DROP TABLE "aws.user"

    To confirm that your table was deleted, you can use the following command.

    SELECT * FROM system_schema.tables WHERE keyspace_name = "aws";

    Your table should not be listed in the output of this statement. Note that there can be a delay until the table is deleted. For more information, see DROP TABLE.
