Deploying the infrastructure

The CloudFormation template that accompanies this lab requires the ability to create IAM Roles and AWS Lambda functions. If the account you are using does not have these capabilities, you will not be able to complete this lab.

Deploy CloudFormation Template

  1. Download the DeployWACustomLambda.yaml CloudFormation template to your machine.

  2. For this lab, you will need to use us-east-2

  3. Go to the AWS CloudFormation console at https://console.aws.amazon.com/cloudformation and click Create Stack > With new resources Images/CFNCreateStackButton

  4. Leave Prepare template setting as-is

    • For Template source select Upload a template file
    • Click Choose file and supply the CloudFormation template you downloaded: DeployWACustomLambda.yaml CFNUploadTemplateFile

  5. Click Next

  6. For Stack name use WALambdaHelpers

  7. Parameters

    • Look over the Parameters and their default values.

    • None of these parameters need to be changed, but are available if you wish to try different settings

    • CreateWALambdaFunctionName - The name for the new CreateWA lambda function.

    • UpdateWAQLambdaFunctionName - The name for the new UpdateWA lambda function.

    • LambdaFunctionsBucket – S3 Bucket name that holds the WAToolCFNAPILambda.zip file

    • WAToolCFNAPIKey - The filename for the Lambda file, WAToolCFNAPILambda.zip

    • Click Next

  8. For Configure stack options we recommend configuring tags, which are key-value pairs, that can help you identify your stacks and the resources they create. For example, enter Owner in the left column which is the key, and your email address in the right column which is the value. We will not use additional permissions or advanced options so click Next. For more information, see Setting AWS CloudFormation Stack Options .

  9. For Review

    • Review the contents of the page
    • At the bottom of the page, select
      • I acknowledge that AWS CloudFormation might create IAM resources.
      • I acknowledge that AWS CloudFormation might create IAM resources with custom names.
      • I acknowledge that AWS CloudFormation might require the following capability: CAPABILITY_AUTO_EXPAND CFNIamCapabilities
    • Click Create stack

  10. This will take you to the CloudFormation stack status page, showing the stack creation in progress.

    • Click on the Events tab
    • Scroll through the listing. It shows the activities performed by CloudFormation (newest events at top), such as starting to create a resource and then completing the resource creation.
    • Any errors encountered during the creation of the stack will be listed in this tab. StackCreationStarted

  11. When it shows status CREATE_COMPLETE, then you are finished with this step.

This template will take between 1-5 minutes to fully deploy.
