AWS Lambda: Dedicated Cloud Gateway configuration - Plugin

Dedicated Cloud Gateway configuration

Set up the plugin to invoke a Lambda function with Dedicated Cloud Gateways.

Prerequisites

An AWS account with access to Lambda.
A Lambda function.
Configure the AWS IAM trust policy for the IAM role that is used to invoke the Lambda function. For example:
```
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "AWS": "arn:aws:iam::$DCGW_ACCOUNT_ID:role/$NETWORK_ID-dataplane"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}
```
You can find your account ID and network ID in Konnect by navigating to your Data Plane and Networks in Gateway Manager.

Environment variables

AWS_KEY: Your AWS access key ID.
AWS_SECRET: Your AWS secret access key.
AWS_REGION: Your AWS region.
LAMBDA_FUNCTION: The name or ARN of the Lambda function to invoke.
AWS_ASSUME_ROLE_ARN: The ARN of the IAM role used to invoke Lambda function. For example, arn:aws:iam::YOUR_ACCOUNT_ID:role/YOUR_ROLE

Set up the plugin

Add this section to your declarative configuration file:
