Chrome在使用Docker业务时未被捕获

我想在Docker容器中使用chrome运行一些业力testing。 我的Dockerfile看起来像：

FROM node:6-alpine RUN apk update \ && apk add --update alpine-sdk \ && apk add chromium \ && npm install -g @angular/cli@1.0.0 \ && ng set --global packageManager=yarn \ && apk del alpine-sdk \ && rm -rf /tmp/* /var/cache/apk/* *.tar.gz ~/.npm \ && npm cache clear \ && sed -i -e "s/bin\/ash/bin\/sh/" /etc/passwd ENV CHROME_BIN=/usr/local/bin/my-chrome-build 

当我在这个容器中运行ng test时（安装了一个我知道工程的项目），我得到：

 $ ng test -sr && yarn run test:server 04 04 2017 10:32:27.896:INFO [karma]: Karma v1.5.0 server started at http://0.0.0.0:9876/ 04 04 2017 10:32:27.915:INFO [launcher]: Launching browser Chrome with unlimited concurrency 04 04 2017 10:32:27.985:INFO [launcher]: Starting browser Chrome 04 04 2017 10:33:28.047:WARN [launcher]: Chrome have not captured in 60000 ms, killing. 04 04 2017 10:33:30.053:WARN [launcher]: Chrome was not killed in 2000 ms, sending SIGKILL. 04 04 2017 10:33:32.056:WARN [launcher]: Chrome was not killed by SIGKILL in 2000 ms, continuing. error Command failed with exit code 1. 

我真的不知道如何debugging，有什么想法可能是错误的，或者我怎么能找出更多？
