## What it does

The skill hands your agent ready `gcloud functions deploy` commands for both Gen1 and Gen2, plus function examples in Python and Node.js and a comparison table of the two generations. Useful when you need a webhook, a bucket upload handler or a cron task without running a server.

It covers enabling the required APIs, IAM setup, deploying with triggers, reading logs and deleting functions. There are samples built on `functions-framework`, work with Pub/Sub, Firestore and Cloud Vision, and a Terraform config for `google_cloudfunctions2_function`. Local testing is covered too: `functions-framework --target=hello_http --port=8080`.

Before the first deploy you need an authenticated `gcloud`, the Cloud Functions, Cloud Build, Artifact Registry and Cloud Run APIs enabled, and the `roles/cloudfunctions.developer` role (or `roles/run.developer` for Gen2). Skip that and the deploy fails during the build step. Gen2 functions run on top of Cloud Run, so traffic billing lands there — worth checking your quotas first.

## Requirements
- Works with: Terraform

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add BagelHole/DevOps-Security-Agent-Skills --skill gcp-cloud-functions -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/gcp-cloud-functions/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/gcp-cloud-functions/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add BagelHole/DevOps-Security-Agent-Skills --skill gcp-cloud-functions -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/gcp-cloud-functions/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add BagelHole/DevOps-Security-Agent-Skills --skill gcp-cloud-functions -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/gcp-cloud-functions/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install BagelHole/DevOps-Security-Agent-Skills gcp-cloud-functions
```

2. **Manually: put the files in place**
- File: `.github/skills/gcp-cloud-functions/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add BagelHole/DevOps-Security-Agent-Skills --skill gcp-cloud-functions -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/BagelHole/DevOps-Security-Agent-Skills --path infrastructure/cloud-gcp/gcp-cloud-functions
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/gcp-cloud-functions/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add BagelHole/DevOps-Security-Agent-Skills --skill gcp-cloud-functions -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/BagelHole/DevOps-Security-Agent-Skills/tree/HEAD/infrastructure/cloud-gcp/gcp-cloud-functions/SKILL.md

## When to use it
- deploy an HTTP function to Google Cloud Functions
- wire a function to a Pub/Sub topic
- process file uploads landing in Cloud Storage
- run a scheduled job without keeping a server
- pick between Gen1 and Gen2 by memory and timeout limits

## Example prompts
- Deploy the hello-http HTTP function to us-central1 on python312
- Set up process-order with an order-events topic trigger and retries
- Show me how to read the last 50 log entries for hello-http

# GCP Cloud Functions

Build and deploy event-driven serverless applications with Google Cloud Functions (Gen1 and Gen2).

## When to Use

- Processing webhooks, API endpoints, or lightweight HTTP backends
- Reacting to events from Pub/Sub, Cloud Storage, Firestore, or Eventarc
- Running scheduled tasks (cron) without maintaining a server
- Building data-processing pipelines triggered by file uploads
- Prototyping microservices before committing to Cloud Run or GKE

## Prerequisites

- Google Cloud SDK (`gcloud`) installed and authenticated
- APIs enabled: Cloud Functions, Cloud Build, Artifact Registry, Cloud Run (Gen2)
- IAM role `roles/cloudfunctions.developer` (or `roles/run.developer` for Gen2)

```bash
gcloud services enable cloudfunctions.googleapis.com cloudbuild.googleapis.com \
  artifactregistry.googleapis.com run.googleapis.com eventarc.googleapis.com
```

## Gen1 vs Gen2 Comparison

| Feature | Gen1 | Gen2 (recommended) |
|---------|------|---------------------|
| Runtime | Cloud Functions infra | Built on Cloud Run |
| Max timeout | 9 minutes | 60 minutes |
| Max memory | 8 GB | 32 GB |
| Concurrency | 1 request/instance | Up to 1000/instance |
| Traffic splitting | No | Yes |
| Eventarc triggers | No | Yes |

## Deploy an HTTP Function (Gen2)

```bash
# Python HTTP function
gcloud functions deploy hello-http \
  --gen2 --region=us-central1 --runtime=python312 \
  --trigger-http --allow-unauthenticated \
  --entry-point=hello_http \
  --memory=256Mi --timeout=60s \
  --min-instances=0 --max-instances=100 \
  --set-env-vars=APP_ENV=production --source=.

# Node.js HTTP function
gcloud functions deploy hello-node \
  --gen2 --region=us-central1 --runtime=nodejs20 \
  --trigger-http --allow-unauthenticated \
  --entry-point=helloNode --memory=256Mi --source=.
```

## Deploy a Pub/Sub Triggered Function

```bash
gcloud pubsub topics create order-events

gcloud functions deploy process-order \
  --gen2 --region=us-central1 --runtime=python312 \
  --trigger-topic=order-events \
  --entry-point=process_order \
  --memory=512Mi --timeout=120s --retry \
  --service-account=order-processor@${PROJECT_ID}.iam.gserviceaccount.com \
  --source=.
```
