So what I've done previously is to have a folder with the handler code in it and then in the root have a bash script that does the

pip install

and then pulumi up. Then in the pulumi code for the function have something like

code=pulumi.AssetArchive({".": pulumi.FileArchive("app")})

Pulumi will then zip everything up for you and push it up

so something like:

Copy code

myfunction = aws.lambda_.Function(
    "myfunction",
    memory_size=256,
    runtime="python3.8",
    handler="app.handler",
    code=pulumi.AssetArchive({".": pulumi.FileArchive("app")}),
    role=function_role.arn,
    timeout=60,
)

And then the bash script is something like:

Copy code

#!/bin/bash

pushd ./app

pip3 install -r requirements.txt -t .

popd

pulumi up

so I just need to run the bash script to install the requirements and run pulumi up

A lot of text, but hopefully that helps

So, thanks to your help I now have something I'm not to unhappy with - I wrapped the pip installing of dependencies into a custom (dynamic) pulumi resource/provider, that gets called before the lambda. It's still a bit shaky (in particular, Asset/File archives can't take an Output in apparently, which is a bit messy), but I'll probably share my code once it's a bit cleaner
