我们可以为Zalenium集线器创建副本集吗

Question

我正在尝试使用kubernetes复制zalenium集线器，但我遇到了问题。单个zalenium集线器工作正常。如果我添加的副本数超过1，则在zalanium预览页(http://zalenium:port/admin/grid/live)中显示403禁止，502坏网关，无VNC..etc

它有时在实时预览页面中显示502坏网关，在zalenium容器中显示403禁止，没有VNC。

请告诉我如何解决这个问题。

这是我运行时的kubernetes部署文件。

Expecting it should be run like a single zalenium hub.

Answer 1

这是不可能的，Zalenium只与一个集线器一起工作，所以只允许一个副本。
