Deploying a Connector Proxy as an AWS Lambda Function
This guide shows you how to deploy the demo Connector Proxy as an AWS Lambda Function as well as how to integrate it with SpiffArena. The Getting Started Guide will be used as the basis for integration but the steps should easily map to any custom installation.
There is an assumption that you have access to login to the AWS Console and can create/deploy Lambda functions.
Building the zip
One option when deploying a Lambda function is to upload a zip file containing the source code or executable. In the root of this repository run:
make zip
This will create a zip file containing the lambda entry point function as well as all the dependencies needed to execute the connectors. For this example the libraries spiffworkflow-proxy is used for discovering connectors and connector-http is an example connector that provides http get and post requests.
Once make zip completes connector_proxy_lambda_demo.zip will be available in the repository root.
Creating the Lambda Function
Log in to the AWS Console and navigate to the Lambda section.
From there choose Create function.
Choose to Author from scratch and select the most recent Python runtime.
Under Advanced Settings check Enable function URL. For this demo we will use the NONE auth type to keep things simple.
After hitting the Create function button you will be taken to your new Lambda function:
In the bottom right of the first section is a link to your Lamba's function URL. Click it for a hello world response.
Deploying the Lambda Function
If you scroll down you will see a section with the example code created with your Lambda function. We are going to replace this with the contents of our zip file. Choose Upload from and select .zip file.
After a confirmation dialog you will see your lambda has been updated:
Click your function URL again to see a hello from our deployed Connector Proxy.
Integrating With SpiffArena
Congrats, your Connector Proxy has been deployed as a Lambda function. For information on configuring SpiffArena to use the new Connector Proxy url please see Configure a Connector Proxy.
