ChromeHeadless (Puppeteer) not captured when running in docker

Trying to convert my karma config from phantomjs to puppeteer but I’m facing issues when running my test suite. Here’s the log:

[18:25:41] Starting 'karma'...
29 01 2018 18:26:37.287:INFO [karma]: Karma v2.0.0 server started at http://0.0.0.0:9876/

29 01 2018 18:27:41.532:WARN [launcher]: ChromeHeadless was not killed by SIGKILL in 2000 ms, continuing.

After debugging, the CHROME_BIN is available here: /tmp/webcore/node_modules/puppeteer/.local-chromium/linux-526987/chrome-linux/chrome

And the karma config are these:

{ action: 'run',
  singleRun: true,
  browsers: [ 'ChromeHeadless' ],
  reporters: [ 'junit', 'dots' ],
  configFile: '/tmp/webcore/test/unit/config/karma.conf' }

Also tried using a custom launcher with the --no-sandbox option, but same issue… 😕

Any help is definitely welcome.

Same issue for me using Angular 7. Running docker inside Jenkins.

karma.conf.js:

};

Had same problem, when I ran tests using Gitlab CI. I just added

before_script:
    - export CHROME_BIN=/usr/bin/google-chrome
