Chromium headless hanging/ crashing in docker

[anon18728271]

Hi, i have read almost all the trades about browser crashing in docker yet non of the solution is helping me and i'm still stuck with the crashing browser error.

each time i run the test it hangs or crashes on different part of the test (the SUT is internal therefore can't share the page).

docker file:

FROM testcafe/testcafe
RUN whoami
COPY --chown=user:user . /opt/testcafe/e2e-tests
RUN cd /opt/testcafe/e2e-tests/ && npm cache clean --force && npm install && rm -rf /tmp/*
WORKDIR /opt/testcafe/e2e-tests
ENTRYPOINT ["/opt/testcafe//e2e-tests/testcafe-docker.sh"]

testcafe-docker.sh:
#!/bin/sh
XVFB_SCREEN_WIDTH=${SCREEN_WIDTH-1280}
XVFB_SCREEN_HEIGHT=${SCREEN_HEIGHT-720}

dbus-daemon --session --fork
Xvfb :1 -screen 0 "${XVFB_SCREEN_WIDTH}x${XVFB_SCREEN_HEIGHT}x24" >/dev/null 2>&1 &
export DISPLAY=:1.0
fluxbox >/dev/null 2>&1 &
node ./node_modules/.bin/testcafe -s '/tmp' 'chromium:headless --no-sandbox --disable-gpu-sandbox --disable-gpu' './tests/onboard-merchant/onboard-with-online-payment.js'

first i build the docker with "docker build . -t e2e"
then run the test with "docker run -v $HOME/tmp:/tmp -it e2e"

test fails with:
ERROR The HeadlessChrome 63.0.3239 / Linux 0.0.0 browser disconnected. This problem may appear when a browser hangs or is closed, or due to network issues.

Alternatively can i install nightmare in docker and user it instead of chromium?

It is difficult to determine the cause of the issue without reproducing it locally. Would you please provide us with a link to your web site or emulate this problem with a brand new project?

Yes, you can.

how do i install nightmare on testcafe docker?

[anon18728271]

this page can't be shared it's internal financial web application, i would've liked to give a link but it's not possible and i understand you.

the only information i can give now is that the application frontend is written in angular (although i used a testcafe Selector and not testcafe angular selector) which run fine locally on my MacOS

how do i install nightmare on testcafe docker?

I've discussed your scenario with the R&D team and we found that our docker image does not suit you. I suggest you use one of circleci node.js images (e.g.circleci/node:10-browsers) as a base image and install TestCafe and testcafe-browser-provider-nightmare there.

[anon18728271]

i asked of nightmare (which i don't personally think is a better option compared to chromium/chrome) just because i can't get the chromium to stop crashing in testcafe docker.

I will so much apprecciate any pointer to how i can make the chromium headless to stop crashing or install chrome on testcafe docker

I have no idea why the issue occurs, because we've never been informed about it before. Would you please replicate the issue with a stand-alone project?

[anon18728271]

yes i can however:
a) i can't use my company url as you can't access it outside without appropriate privileges
b) i have tried couple of sample angular web pages and they all pass

can i run chromium in normal mode (do i need to install it or normal chrome)? if yes, what are the parameters do i need to use or leave out ? e.g. screensize,etc...
