How to use PNPM with Google Cloud Build?

Question

I'd like to migrate to PNPM, however, I can't find a way to use its lockfile on Google Cloud. My current cloudbuild config is the following:

steps:
- name: "gcr.io/google.com/cloudsdktool/cloud-sdk:latest"
  entrypoint: 'gcloud'
  args: ["app", "deploy"]
timeout: "1600s"

Afaik these official images only support Yarn and NPM. Is there an easy way to replace Yarn with PNPM here?

I looked on the Cloud Builders GitHub repo, but there's no PNPM there either.

IIUC the App Engine standard Node runtime(s) require that you use npm or yarn. PNPM is thus not user-definable when using standard.

https://cloud.google.com/appengine/docs/standard/nodejs/specifying-dependencies

If you want to use App Engine with a different package manager you could use flex and define a custom runtime. This essentially allows you to define a container image to deploy to App Engine and this may be anything that exposes an httpd on :8080.

You might be able to use pnpm install followed by npm shrinkwrap. I think gcloud deploy will ignore what's in node_modules in favor of package-lock.json but you could delete it.

npm i -g pnpm && pnpm i && npm shrinkwrap

That's npm shrinkwrap. There is pnpm shrinkwrap but that generates a pnpm-style lockfile.

You can use bash:

- id: Install pnpm
  name: 'node:20'
  script: |
    #!/usr/bin/env bash
    npm install --global [email protected]
    pnpm install
    pnpm test

Another method using bash as entrypoint with args

  - name: 'node:latest'
    entrypoint: 'bash'
    args: 
      - '-c'
      - |
        npm install -g pnpm &&
        pnpm install &&
        pnpm run build
