Hello, I am trying to add a

.env

file to a

python_awslambda

. We are already using a macro so because we have some docker lambdas and some just zips. I believe I have it set up right, but I'm wondering if I should be seeing the

.env

file inside the zip or is this just something that pex handles? If I run

pants package

and then unzip the

/dist/lambda.zip

I don't see the file in there.

Tony, can you post a link to a repo where the issue can be reproduced (ideal if you can make one), or paste relevant bits of your BUILD file(s) and/or pants.toml?

Private repo so I can't post that. Let me gather some examples of my BUILD files and folder structure though. If that won't work, I can create an example repo.

I might have been lead to my problem simply by running pants tailor... Here is what the folder structure looks like:

Copy code

├── service
│   ├── lambda_code
│   │   ├── infrastructure.py
│   │   └── runtime
│   │       ├── BUILD
│   │       └── lambda_function.py
├── config
│   ├── __init__.py
│   └── .dev.env

And in my macro, I was adding the file like this:

Copy code

file(
        name="env",
        source=f"config/.{env('STAGE')}.env",
    )

but that seems to point to

service/lambda_code/runtime/config/.dev.env

So I need to figure out how to get the file path correctly

Tony, the documentation in https://www.pantsbuild.org/docs/assets#files warns that an asset added with

file

would not be added to an archive like a python_awslambda. Could this be the issue?

Oh yes. That's certainly relevant too. I will switch to

resource

Is there a way to traverse up a directory from the BUILD file though?

If you look at my folder structure example, the config is not in the same directory as my BUILD

we should move the BUILD up 🙂

late-advantage-75311

to the parent

or probably have BUILDs in both.

I probably need both

You'll also need to read the file in a slightly different way in your consuming code once you mark it as a resource. but all of that is very nicely documented in the docs/assets page

because there is sometimes multiple services:

Copy code

├── service
│   ├── lambda_code
│   │   ├── infrastructure.py
│   │   └── runtime
│   │       ├── BUILD
│   │       └── lambda_function.py
├── service2
│   ├── lambda_code
│   │   ├── infrastructure.py
│   │   └── runtime
│   │       ├── BUILD
│   │       └── lambda_function.py
├── config
│   ├── __init__.py
│   └── .dev.env

and both services would need the config
