standalone-chrome: Unable to create session when run with `--network=host`

[olivergondza]

🐛 Bug Report

When run with --network=host, any attempt to create new session in for standalone-chrome(-debug) container fails with:

Unable to create new session.

SessionNotCreatedError: session not created
from disconnected: unable to connect to renderer
  (Session info: chrome=70.0.3538.77)
  (Driver info: chromedriver=2.43.600233 (523efee95e3d68b8719b3a1c83051aa63aa6b10d),platform=Linux 5.5.2-arch1-1 x86_64) (WARNING: The server did not provide any stacktrace information)
Command duration or timeout: 371 milliseconds
Build info: version: '3.14.0', revision: 'aacccce0', time: '2018-08-02T20:13:22.693Z'
System info: host: 'arch', ip: 'Unknown', os.name: 'Linux', os.arch: 'amd64', os.version: '5.5.2-arch1-1', java.version: '1.8.0_181'
Driver info: driver.version: unknown

To Reproduce

Steps to reproduce the behavior (including the command to start the containers):

• $ docker run -d --shm-size=2g --network=host selenium/standalone-chrome-debug:3.141.59-zinc
• Navigate to http://localhost:4444/wd/hub/ and create chrome session
• Fails as reported -^

Expected behavior

The expected behavior can be reproduced by:

$ docker run -d --shm-size=2g --network=host selenium/standalone-firefox-debug:3.141.59-zinc
docker run -d --shm-size=2g -p 4444:4444 selenium/standalone-chrome-debug:3.141.59-zinc

Creating session works as expected. Note there is no apparent difference between -debug images or version 3.14.0.

12/02/2020 11:20:57 X DAMAGE available on display, using it for polling hints.
12/02/2020 11:20:57   To disable this behavior use: '-noxdamage'

12/02/2020 11:20:57   Most compositing window managers like 'compiz' or 'beryl'
12/02/2020 11:20:57   cause X DAMAGE to fail, and so you may not see any screen
12/02/2020 11:20:57   updates via VNC.  Either disable 'compiz' (recommended) or
12/02/2020 11:20:57   supply the x11vnc '-noxdamage' command line option.

12/02/2020 11:20:57 Wireframing: -wireframe mode is in effect for window moves.
12/02/2020 11:20:57   If this yields undesired behavior (poor response, painting
12/02/2020 11:20:57   errors, etc) it may be disabled:
12/02/2020 11:20:57    - use '-nowf' to disable wireframing completely.
12/02/2020 11:20:57    - use '-nowcr' to disable the Copy Rectangle after the
12/02/2020 11:20:57      moved window is released in the new position.
12/02/2020 11:20:57   Also see the -help entry for tuning parameters.
12/02/2020 11:20:57   You can press 3 Alt_L's (Left "Alt" key) in a row to

12/02/2020 11:20:57   periodic repaints.

12/02/2020 11:20:57 XFIXES available on display, resetting cursor mode

12/02/2020 11:20:57   to disable this behavior use: '-cursor arrow'
12/02/2020 11:20:57   or '-noxfixes'.
12/02/2020 11:20:57 using XFIXES for cursor drawing.

12/02/2020 11:20:57   (induced by either user keystroke or mouse input).
12/02/2020 11:20:57   If this yields undesired behavior (poor response, painting

12/02/2020 11:20:57   Automatically switching to -xkb mode.
12/02/2020 11:20:57   If this makes the key mapping worse you can
12/02/2020 11:20:57   disable it with the "-noxkb" option.

******************************************************************************
Have you tried the x11vnc '-ncache' VNC client-side pixel caching feature yet?

The scheme stores pixel data offscreen on the VNC viewer side for faster
retrieval.  It should work with any VNC viewer.  Try it by running:

    x11vnc -ncache 10 ...

One can also add -ncache_cr for smooth 'copyrect' window motion.
More info: http://www.karlrunge.com/x11vnc/faq.html#faq-client-caching

The log shows:

Chrome 70 and ChromeDriver 2.43 are a bit old, and are not the contents of 3.141.59-zinc

[olivergondza]

@diemol, see the "Docker-Selenium image version" reported. I run into this with 3.14.0, tried 3.141.59-zinc in hope things would improve / provide more details, but the result is the same in both versions.

[diemol]

@olivergondza but the logs you provided (which I mentioned in my previous comment) show different versions of Chrome and ChromeDriver.
The zinc release
has:
Google Chrome: 79.0.3945.117
ChromeDriver: 79.0.3945.36

But your logs show chrome=70.0.3538.77 and chromedriver=2.43.600233, so it is not clear what you are using.

Are you sure you are not using a local Chrome/ChromeDriver? Can you please provide an automation script to reproduce the issue?

[olivergondza]

@diemol, right, those are the versions from the 3.14.0 container. They do differ there:

You are correct the versions do not differ in 3.141.59-zinc, but as I said, the problem manifests there just the same. Let me harvest the logs from 3.141.59-zinc.

17/02/2020 11:41:45 
17/02/2020 11:41:45   Most compositing window managers like 'compiz' or 'beryl'
17/02/2020 11:41:45   cause X DAMAGE to fail, and so you may not see any screen
17/02/2020 11:41:45   updates via VNC.  Either disable 'compiz' (recommended) or
17/02/2020 11:41:45   supply the x11vnc '-noxdamage' command line option.

17/02/2020 11:41:45 Wireframing: -wireframe mode is in effect for window moves.
17/02/2020 11:41:45   If this yields undesired behavior (poor response, painting
17/02/2020 11:41:45   errors, etc) it may be disabled:
17/02/2020 11:41:45    - use '-nowf' to disable wireframing completely.
17/02/2020 11:41:45    - use '-nowcr' to disable the Copy Rectangle after the
17/02/2020 11:41:45      moved window is released in the new position.
17/02/2020 11:41:45   Also see the -help entry for tuning parameters.

17/02/2020 11:41:45   to disable this behavior use: '-cursor arrow'
17/02/2020 11:41:45   or '-noxfixes'.
17/02/2020 11:41:45 using XFIXES for cursor drawing.

17/02/2020 11:41:45   If this makes the key mapping worse you can
17/02/2020 11:41:45   disable it with the "-noxkb" option.

******************************************************************************
Have you tried the x11vnc '-ncache' VNC client-side pixel caching feature yet?

The scheme stores pixel data offscreen on the VNC viewer side for faster
retrieval.  It should work with any VNC viewer.  Try it by running:

    x11vnc -ncache 10 ...

One can also add -ncache_cr for smooth 'copyrect' window motion.
More info: http://www.karlrunge.com/x11vnc/faq.html#faq-client-caching

How can I reproduce that? I don't see an automation script that I can run to get the same result.

[olivergondza]

I have not created one since it is just launching the container, Navigate to http://localhost:4444/wd/hub/, click "Create Session", select "chrome" and click "OK".

This is the minimal reproducer. It of course fails the same way when I try to connect from Java selenium.

[diemol]

I just read again the container logs you posted and actually they look fine, where is the error message coming from?

[olivergondza]

As strange as it is, I am not able to reproduce this after the month. In the mean time, I have

• kernel 5.5.13.arch1-1
• docker 19.03.8-ce, build afacb8b7f0

just in case it is relevant. Thanks for your assistance.

[diemol]

Thanks for replying, closing this for now.
