Debian Docker K8s 上的 Puppeteer/Chromium：“无法打开 X11 连接”

Question

这让我发疯，没想到让一个使用 puppeteer 启动配置运行的无头 chromium 实例会这么难。

这是错误：

# launching puppeteer with config {"args":["--no-sandbox","--disable-setuid-sandbox","--disable-dev-shm-usage","--disable-accelerated-2d-canvas","--no-first-run","--no-zygote","--single-process","--disable-gpu","--headless"],"headless":true,"devtools":false,"timeout":90000,"executablePath":"/usr/bin/chromium","dumpio":true}

[0124/153812.592511:WARNING:audio_manager_linux.cc(69)] Falling back to ALSA for audio output. PulseAudio is not available or could not be initialized.

这是我的 Dockerfile：

COPY . /usr/src/app

RUN yarn install

RUN chmod -R 777 /usr/src/app

ENTRYPOINT [ "./entrypoint.sh" ]
EXPOSE 80

这是我的entrypoint.sh：

#!/bin/bash

# Startup Xvfb
Xvfb -ac :99 -screen 0 1280x1024x16 > /dev/null 2>&1 &

# Export some variables
export DISPLAY=:99.0

npm run-script deploy-force && npm start && sleep 6000

这是我的 Puppeteer 配置：

const puppeteerConfig = {
    args: [
        '--no-sandbox',
        '--disable-setuid-sandbox',
        '--disable-dev-shm-usage',
        '--disable-accelerated-2d-canvas',
        '--no-first-run',
        '--no-zygote',
        '--single-process', // <- this one doesn't works in Windows
        '--disable-gpu',
        '--headless'
    ],
    headless: true,
    devtools: false,
    timeout: 90000,
    executablePath: '/usr/bin/chromium',
    dumpio: true
};

我以为通过运行Xvfb我的 x11 连接就会发生？
