karma phantomjs没有在docker容器中捕获

我无法让phantomjs在高山码头集装箱中捕获业力.我正在使用节点6.10.2.我从here安装了phantomjs alpine.我使用的是以下版本：

"karma": "^1.6.0","karma-coverage": "^1.1.1","karma-mocha": "^1.0.1","karma-mocha-reporter": "^2.0.0","karma-phantomjs-launcher": "^1.0.4","karma-webpack": "^2.0.3",

当我运行测试时,在我的容器内部,我看到以下输出. (删除时间戳)

INFO [karma]: Karma v1.6.0 server started at http://0.0.0.0:9876/
INFO [launcher]: Launching browser PhantomJS with unlimited concurrency
INFO [launcher]: Starting browser PhantomJS
DEBUG [temp-dir]: Creating temp dir at /workspace/karma-1981971
DEBUG [launcher]: /usr/bin/phantomjs /workspace/karma-1981971/capture.js
WARN [launcher]: PhantomJS have not captured in 60000 ms,killing.

然后在退出之前失败2次.

当我查看tmp文件capture.js的内容时,它显示它正在尝试打开localhost：9876 /？id = 18274999并在我的容器内我尝试wget http：//0.0.0.0：9876 /确实成功了.

所以我很困惑为什么PhantomJs无法捕捉到我确实可以从我的容器内连接.

我该如何调试呢？任何建议都非常感谢
