当 Chromium 成功启动时,它的 Debugging WebSocket URL 应该类似于ws://127.0.0.1:9222/devtools/browser/ec261e61-0e52-4016-a5d7-d541e82ecb0a.
127.0.0.1:9222应该能够通过 Chrome 浏览以检查无头 Chromium。但是,在对我的应用程序进行 dockerize 后,我无法通过 Chrome 访问远程调试器 URL。
由 Puppeteer 启动铬的launchOption:

"--disable-setuid-sandbox"
],
"defaultViewport": {
