docker工具中的angular色testing运行者不会在浏览器中打开

我可以运行testing，看看cli上的testing报告，但我想看浏览器上的testing报告。 如何在浏览器上查看业务testing报告？

这里是docker文件，从节点：8.2.1

# Install Google Chrome RUN wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add - RUN sh -c 'echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list' RUN apt-get update && apt-get install -y google-chrome-stable RUN mkdir -p /walaa.co WORKDIR /walaa.co COPY package.json /walaa.co/package.json RUN ["yarn", "install"] COPY . /walaa.co ENV CHROME_BIN /usr/bin/google-chrome EXPOSE 4200/tcp CMD ["yarn", "start", "--", "--host", "0.0.0.0"] 

这里是karma.conf.js文件

 // Karma configuration file, see link for more information // https://karma-runner.github.io/1.0/config/configuration-file.html module.exports = function (config) { config.set({ basePath: '', frameworks: ['jasmine', '@angular/cli'], plugins: [ require('karma-jasmine'), require('karma-chrome-launcher'), require('karma-jasmine-html-reporter'), require('karma-coverage-istanbul-reporter'), require('@angular/cli/plugins/karma') ], client:{ clearContext: false // leave Jasmine Spec Runner output visible in browser }, coverageIstanbulReporter: { reports: [ 'html', 'lcovonly' ], fixWebpackSourcePaths: true }, angularCli: { environment: 'dev' }, reporters: ['progress', 'kjhtml'], port: 9876, colors: true, logLevel: config.LOG_INFO, autoWatch: true, browsers: ['Chrome_without_sandbox'], customLaunchers: { Chrome_without_sandbox: { base: 'ChromeHeadless', flags: [ '--no-sandbox', '--headless', '--disable-gpu', '--remote-debugging-port=9876' ] } }, singleRun: false }); }; 

我的docker文件或karma.conf.js有问题吗？
