在docker-compose中运行webdriverIO

Question

我正在努力了解如何正确配置撰写文件以运行webdriverio。

我正在按照说明进行操作：

https://github.com/SeleniumHQ/docker-selenium/wiki/Getting-Started-with-Docker-Compose

在这里

https://github.com/blueimp/wdio/blob/master/docker-compose.yml

我主要是在努力了解我应该拥有哪些集线器以及什么取决于什么。欢迎任何输入

这是我的docker-compose文件

            SELENIUM_APP_ADMIN_URL: 'http://192.168.0.10:9000/admin/'

这是我的Dockerfile

我在控制台中遇到的最后一个错误是
