We use pulumi to do IaC and we use a monorepo with Bazel as the build tool. We have out modules set out as following

One of the requirements we have is to build a lambda module and then deploy it. The lambda module is a target being built by Bazel (golang, but shouldn’t matter):

go_binary(
    name = "lambda_module",
    visibility = ["//visibility:public"],
)

We then have the iac module, which should get the built version of the above module, so that it can then upload it into lambda

go_binary(
    name = "iac",
    args = [
        "-lambda_module",
        "$(location //products/productA/module/lambda_module)",
    ],
    data = ["//products/productA/module/lambda_module"],
    visibility = ["//visibility:public"],
)
