Google Cloud Functions v2 - is it possible to define function resources (such as memory) progammatically?

Question

I haven't been able to find anything on this, but it seems like it must exist as having to configure this via console isn't great.

I want to configure the appropriate memory allocation per function that is provisioned to Google Cloud Functions. I know it can be changed from defaults via two methods:

1. On the Cloud Function webpage for the given function, after the function has been deployed.

2. During command-line deployment if you use gcloud functions deploy but seemingly not if you use firebase deploy, such as...

gcloud functions deploy myFunc --memory=128MB

But it seems like there should be a way to provision this via a JSON configuration along side the code itself, or something similar. Does anyone know if this is possible?

Answer 1

The closest that exists is what the commenter mentions above, which would look something like this...

exports.myFunction = onTrigger(
  {
    minInstances: 5,
    maxInstances: 10,
    timeoutSeconds: 180,
    memory: "512MB",
    cpu: 2
  },
  (event) => {
    // cloud function body
  }
);
