Run Container image Lamda with runtime args

Hi - Just to clarify, your main concern is don't want to rebuild the Lambda custom image that is part of a Cfn custom resource? If so, is it possible to have your Lambda function in a separate CloudFormation template and reference the ARN? Also where is the config file you are referring to stored right now?

Thanks for the answers. I have a follow-on question please. I am using a cloudformation custom resource to invoke this lambda whenever there is changes to my config file. In other words it is invoked whenever the custom resource is created, updated, or deleted, AWS Cloud formation calls this lambda. Each invocation of this lambda will use a different config. I have to make this config accessible to this lambda created in the cdk. It is a large config file, I cannot put contents of this config into env variables

const myHandler = new NodejsFunction(this, "myHandler", {
  runtime: Runtime.NODEJS_14_X,
  entry: "<entry>",
  handler: "handler",
  vpc: <vpc>,
  securityGroup: <sg>,
  functionName: "<funcName>",
  timeout: Duration.minutes(10),
  environment: {
    <env variables>
  },
  role: <role>
});

So, my current situation is I have a custom resource defined like this.

new CustomResource(this, "Resource1", {
  serviceToken: myProvider.serviceToken,
  properties: {
    configsList: <list of config items>
  }
});

Whenever the properties.configList changes the lambda function is invoked when I run cdk deploy. If there are no changes to the configsList then the lambda is not called. This is working well when my lambda is a nodejs function.

But now my lambda is a container that I need to run and supply this configsList to it as a file. I am unable to figure out a way to do this.
