firefox cannot connect

[kullervo16]

When I use your templates in OSE 3.1 and selenium 2.53.1 encounter some problems with the node-firefox image. It needs to have access to /opt/selenium, if I relax that condition it starts up fine, registers itself in the grid but I get this error:

I have the same error when I use a standalone image from either selenium, some other people or when I package my working VM config... Is there anything special on openshift? Does this container need to be priviledged?

Any suggestions are more than welcome... been fighting this thing for a week now, starts working on my system :-)

hey @kullervo16 !

actually, i'm the maintainer of the selenium docker images and i can tell you, that we are way past 2.53.1. maybe give Selenium 3 a shot, and use the image version: 3 for node-firefox, and hub?

[kullervo16]

thanks for the quick reply.

Got it working, however some observations that might be useful for other people:

• templates worked fine out-of-the-box in my origin 3.3
• on OSE 3.1, I did get issues starting the node images... a permission issue prevented the start. Relaxing that via

FROM selenium/node-chrome:3.0.1
USER root
RUN chmod -R 777 /opt/selenium
RUN echo "2a54b938e3f511e6bf01fe55135034f3" > /etc/machine-id

does the trick. The /etc/machine-id fixes a dbus warning

• the grid comes up and the nodes register without any problem, however... I cannot get the firefox node to work... it always gives an InvocationTargetException without any further information (so registered ok at the hub, hub passes the data to the node... node goes through the protocol INFO messages and then nothing happens.
• using the chrome image works fine though, both with a 3.0.1 as with our legacy 2.53.1 setup.

Conclusion : moved to chrome iso firefox, and our tests are running again :-)

@ddavison ... Is there any option to run the selenium docker containers without root access? In my organization, the open-shift admin is not interested to give the root access to everyone. Pls advise.
