Deploys Puppeteer browser automation on Google Cloud Run with Docker. Use when running headless browser tasks on Cloud Run, or when the user mentions Cloud Run, Puppeteer, headless Chrome, or serverless browser automation.

Cloud Run + Puppeteer Deployment Guide
Hard-won lessons from deploying Puppeteer to Cloud Run. These are non-obvious gotchas that cost significant debug time.
MUST: Use gen2 Execution Environment
Cloud Run gen1 uses gVisor sandbox — blocks Linux syscalls Chrome needs to create processes. Puppeteer will hang/timeout silently.
gcloud run deploy my-service \
--execution-environment gen2 # <-- required for Chrome/Puppeteer
Never deploy a Puppeteer service on gen1.
MUST: Install Chrome System Dependencies
node:18 base image does not include libraries Chrome needs. Missing any one of these causes launch failure.
FROM node:18
RUN apt-get update && apt-get install -y \
ca-certificates fonts-liberation fonts-ipafont-gothic fonts-wqy-zenhei \
libasound2 libatk-bridge2.0-0 libatk1.0-0 libcairo2 libcups2 \

&& rm -rf /var/lib/apt/lists/*
MUST: Secret Manager mount path ngoài WORKDIR
Nếu mount secret vào cùng path với WORKDIR, volume mount sẽ che toàn bộ thư mục — chỉ còn file secret, code biến mất.
# SAI — mount trùng WORKDIR /app
--set-secrets "/app/service-account.json=my-secret:latest"
# ĐÚNG — mount ra path riêng
--set-secrets "/secrets/service-account.json=my-secret:latest"
ENV GOOGLE_CREDS_PATH=/secrets/service-account.json
Windows/Git Bash warning:
--set-env-varsvới path Unix sẽ bị Git Bash convert thành Windows path. SetENVtrực tiếp trong Dockerfile thay vì truyền qua CLI.
Puppeteer Launch Config cho Cloud Run
const browser = await puppeteer.launch({
headless: 'new',
timeout: 60000, // cold start cần thời gian — mặc định 30s không đủ
args: [
'--no-sandbox',
'--disable-setuid-sandbox',
'--disable-dev-shm-usage', // /dev/shm nhỏ trong container
'--single-process',
'--no-zygote',
'--disable-gpu',
],
});
waitUntil hợp lệ trong Puppeteer
Chỉ có 4 giá trị hợp lệ — 'commit' (từ Playwright) KHÔNG tồn tại:
| Giá trị | Ý nghĩa |
|---|---|
load | Chờ event load (chậm nhất) |
domcontentloaded | Chờ DOM parse xong (khuyên dùng) |
networkidle0 | Không còn request nào trong 500ms |
networkidle2 | ≤ 2 request đang chờ trong 500ms |
Với trang nặng từ server overseas, dùng domcontentloaded + timeout cao + waitForFunction chờ content cụ thể:
await page.goto(url, { waitUntil: 'domcontentloaded', timeout: 120000 });
await page.waitForFunction(
() => document.body && document.body.innerText.includes('target-text'),
{ timeout: 60000 }
);
Block Resource để Tăng Tốc
Chặn images, CSS, fonts giảm băng thông đáng kể — quan trọng khi crawl từ server overseas:
await page.setRequestInterception(true);
page.on('request', (req) => {
if (['image', 'stylesheet', 'font', 'media'].includes(req.resourceType())) {
req.abort();
} else {
req.continue();
}
});
Recommended Cloud Run Deploy Command
gcloud run deploy my-service \
--image gcr.io/PROJECT_ID/my-image \
--region asia-southeast1 \
--platform managed \
--execution-environment gen2 \
--memory 2Gi \
--cpu 2 \
--timeout 300 \
--set-secrets "/secrets/service-account.json=my-secret:latest" \
--allow-unauthenticated
Puppeteer cần ít nhất 2Gi RAM — Chrome dùng nhiều memory.
