4.1.2我在 Kubernetes 集群的最新版本中使用 SeleniumGrid 。
在許多情況下（我會說大約一半），當我通過網格執行測驗時，節點無法終止行程并且不會回到空閑狀態。然后容器一直使用一個完整的 CPU，直到我手動殺死它。
容器中的日志如下：
10:51:34.781 INFO [NodeServer$1.lambda$start$1] - Sending registration event...
10:51:35.680 INFO [NodeServer.lambda$createHandlers$2] - Node has been added

Only local connections are allowed.
Please see https://chromedriver.chromium.org/security-considerations for suggestions on keeping ChromeDriver safe.

我是否配置錯誤？有誰知道我該如何解決這個問題？
uj5u.com熱心網友回復：
如果您不需要使用 Xvfb，您可以將其從您的代碼中洗掉，您的問題將得到解決。
顯然，洗掉
START_XVFB引數后問題就解決了。對于只有時區配置的節點，我還沒有遇到問題。
對于解決方法，您可以嘗試將驅動程式更改為例如Chromedriver。您可以在此處閱讀它們之間的差異。
