我们可以为Zalenium Hub创建复制品集吗?

Question

我正在尝试使用kubernetes复制Zalenium Hub，但我面临问题。单Zalenium Hub工作正常。如果我添加了副本的数量超过1个，那么它显示403禁止，502 Badgateway，Zalanium Live Preview页面中没有VNC..ETC(http：//Zalenium：port/admin/admin/grid/live(

它有时在实时预览页中显示502个badgateway，而403禁止使用，在Zalenium容器中没有VNC。

请告诉我如何解决此问题。

这是我的Kubernetes部署文件。

Expecting it should be run like a single zalenium hub.

Answer 1

是不可能的，Zalenium仅与一个枢纽一起工作，因此只允许一个副本。
