如何在Docker中運行無頭瀏覽器？

Question

我正在用無頭瀏覽器構建爬蟲但是現在我想要dockerize我的應用程序我已經在我的泊塢窗圖像中安裝了chrome但是它在運行腳本時會給我一個錯誤。

StartChrome.js

const chromeLauncher = require('chrome-launcher'); 

chromeLauncher.launch({ 
    port: 9222, 
    chromeFlags: ['--headless','--proxy-server=54.171.181.204:8888','--disable-web-security','--disable-gpu'] 
}).then(chrome => { 
    console.log(`Chrome debugging port running on ${chrome.port}`); 
}); 

ERR

(node:415) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: connect ECONNREFUSED 127.0.0.1:9222 
(node:415) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code. 

當我在命令行中運行它，它會引發我這樣

Failed to move to new namespace: PID namespaces supported, Network namespace supported, but failed: errno = Operation not permitted 
Trace/breakpoint trap

您可以用多克嘗試錯誤像yukinying/chrome-headless-browser或類似圖像：https://hub.docker.com/r/yukinying/chrome-headless-browser/

從描述：

此搬運工圖像包含Linux開發通道鉻 （https://www.chromium.org/getting-involved/dev-channel），與 需要的依賴和運行無頭 模式的命令行參數。
