【问题描述】:
我想用这样的 3D 画布截取网页截图:
import {createServer} from 'http'
import puppeteer from 'puppeteer'
const url = "https://webglfundamentals.org/webgl/webgl-load-obj-w-extents.html";
async function main() {
const browser = await puppeteer.launch({
args: [
"--no-sandbox",
"--use-gl=swiftshader",
"--enable-webgl",
],
headless: true,
dumpio: true,
defaultViewport: { width: 400, height: 300 },
});
const page = await browser.newPage();
await page.goto(url);
await page.waitForNetworkIdle();
await page.waitForSelector("#canvas");
const screenshot = await page.screenshot();
console.log(screenshot);
在我的 Ubuntu 机器上本地运行代码可以正常工作,生成此图像:
在 Docker 容器 (Ubuntu + Node.js + Chrome) 中运行代码不起作用。 它会截取屏幕截图,但 3D 画布不会渲染。

我的目标是在 Kubernetes 集群上运行代码。如何配置我的 Dockerfile 以支持 WebGL?
