name: Build Lambda Layer
|
|
|
|
# Build verification only. Terraform owns Lambda packaging: terraform/artifacts.tf
|
|
# runs terraform/build_packages.sh during plan and carries the resulting zips into
|
|
# the plan as content_base64, so there is no artifact for this workflow to upload
|
|
# and no job here holds AWS credentials.
|
|
#
|
|
# What it does check is that the layer still builds for the Lambda target
|
|
# (python3.12 / arm64) and stays small enough to travel inside a plan. boto3 and
|
|
# friends are stripped by build_packages.sh because the runtime provides them; if
|
|
# that strip ever stops working, the size guard below fails the PR rather than
|
|
# letting a multi-hundred-megabyte plan payload reach HCP Terraform.
