    cfn-api-gateway-restapi

    Purpose

    AWS CloudFormation does not support AWS API Gateway. This is a Lambda-backed custom resource to add the AWS API Gateway's RestApi to CloudFormation.

    This package on NPM
    This package on GitHub

    Implementation

    This Lambda makes use of the Lambda-Backed CloudFormation Custom Resource flow module, cfn-lambda (GitHub / NPM).

    Usage

    See ./example.template.json for a sample CloudFormation template. The example uses Condition statements, Parameters, and dynamic ServiceToken generation fully.

    "ApiLogicalIdInResourcesObject": {
      "Type": "Type": "Custom::ApiGatewayRestApi",
      "Properties": {
        "ServiceToken": "arn:aws:lambda:<cfn-region-id>:<your-account-id>:function:<this-deployed-lambda-name>",
        "Name": "StringNameOfApi",
        "BaseApiId": "10 char alphanum ID for API (will clone API from this ID).",
        "Description": "Plain freetext description."
      }
    }
    

    Updating BaseApiId will require and trigger CloudFormation Resource Replacement

    Installation of the Resource Service Lambda

    Using the Provided Instant Install Script

    The way that takes 10 seconds...

    # Have aws CLI installed + permissions for IAM and Lamdba
    $ npm run cfn-lambda-deploy
    

    You will have this resource installed in every supported Region globally!

    Using the AWS Console

    ... And the way more difficult way.

    IMPORTANT: With this method, you must install this custom service Lambda in each AWS Region in which you want CloudFormation to be able to access the ApiGatewayRestApi custom resource!

    1. Go to the AWS Lambda Console Create Function view:
    1. Zip this repository into /tmp/ApiGatewayRestApi.zip

      $ cd $REPO_ROOT && zip -r /tmp/ApiGatewayRestApi.zip;

    2. Enter a name in the Name blank. I suggest: CfnLambdaResouce-ApiGatewayRestApi

    3. Enter a Description (optional).

    4. Toggle Code Entry Type to "Upload a .ZIP file"

    5. Click "Upload", navigate to and select /tmp/ApiGatewayRestApi.zip

    6. Set the Timeout under Advanced Settings to 10 sec

    7. Click the Role dropdown then click "Basic Execution Role". This will pop out a new window.

    8. Select IAM Role, then select option "Create a new IAM Role"

    9. Name the role lambda_cfn_api_gateway_restapi (or something descriptive)

    10. Click "View Policy Document", click "Edit" on the right, then hit "OK"

    11. Copy and paste the ./execution-policy.json document.

    12. Hit "Allow". The window will close. Go back to the first window if you are not already there.

    13. Click "Create Function". Finally, done! Now go to Usage or see the example template. Next time, stick to the instant deploy script.
