Deploy Lambdas with Terraform

first you shoul have valid AWS credentials exported in your environment

there are few ways to do it, for example by activating one of your AWS profiles:

export AWS_PROFILE=profile-name

or just exporting your keys

export AWS_ACCESS_KEY_ID=************
export AWS_SECRET_ACCESS_KEY=***********

you must have terraform installed

https://learn.hashicorp.com/terraform/getting-started/install.html

play

now you can create a main.tf file under the root of your node lambda project

module "lambda-deploy" {
    source  = "app.terraform.io/roby/lambda-deploy/xxxxxx"
    version = "0.0.1"
    name = "audit_logger"
    region     = "ap-southeast-1"
    src = "./"
    lambdavars = {
        hello1 = "ciao"
        hello2 = 1284698.55
        hello3 = "ciao2"
        hello4 = "ciao3"
    }
}

lambdavars will be injected in the lambda variables configuration and will be available via process.env

name will be the name of your lambda function

src is the source of the lambda (same level of package.json)

now you can run

this will download the dependencies of the module and initialize .terraform state

terraform init

this will create and deploy the lambda in aws

terraform apply -auto-approve

this will destroy

terraform destroy -auto-approve

to add another policy:
