Mill AWS Lambda

Mill plugin to deploy code to AWS Lambda.

Usage

Import the module in build.sc using mill's $ivy import syntax, and extend AwsLambdaModule in your build definition:

import $ivy.`io.github.bbstilson::mill-aws-lambda:0.2.1`

import io.github.bbstilson.AwsLambdaModule

object project extends AwsLambdaModule {
  def scalaVersion = "2.13.6"

  def s3Bucket = "bucket"
  def s3KeyPrefix = "prefix"
  def lambdaName = "my-lambda-name"
  def lambdaHandler = "org.company.Handler::handle"

  // These two are only required if you want to create a lambda.
  def lambdaMemory = Some(512)
  def lambdaRoleArn = Some("arn:aws:iam::1234567890:role/service-role/lambda-role")
}

Then, to deploy:

mill project.deployLambda
