basic

Basic example

Minimal VPC (modules/vpc) + security group + two modules:

• lambda_managed_instance — capacity provider, operator role, and service-linked role wiring
• lambda_managed_function — execution role, CloudWatch log group, and python3.14 sample function (via capacity_provider_arn from the first module)

Same shape as the repository root stack, but with its own working directory and state file.

Defaults use lmi-basic and 10.0.0.0/16 (two AZs). Use a different vpc_cidr / name_prefix in terraform.tfvars if you deploy multiple examples in one account and region.

Apply

cd examples/basic
terraform init
terraform plan
terraform apply

Optional: add a terraform.tfvars file to override aws_region, vpc_cidr, name_prefix, or other variables from variables.tf.

Invoke after apply

aws lambda invoke \
  --function-name "$(terraform output -raw lambda_function_name):$(terraform output -raw lambda_version)" \
  --payload '{"test":true}' \
  --cli-binary-format raw-in-base64-out /tmp/out.json && cat /tmp/out.json

First apply can take several minutes while capacity and the published version become active.
