Hello,
unfortunatelly I've never tested this particular scenario and I'm not sure if this particular image is ready for it.
I did some quick experiments and I see pretty many error messages. I can provide only a few first thoughts at the moment, but maybe you get some ideas out of it.
-
I hope you test it on Linux and not on Windows.
-
You don't need to expose the ports 5901 and 6901 again, because they are already exposed by the base image.
-
I would add the following options to the command line:
--disable-gpu --headless
. -
However, even then there are still messages about not been able to create some directories, so I would try to run the container as a root. For example by adding
USER 0
to the Dockerfile. You'll also need to add the option--no-sandbox
to the command line in this case.
After using a Dockerfile like this
FROM accetto/ubuntu-vnc-xfce-chromium-g3:latest
USER 0
EXPOSE 9222
CMD ["/usr/bin/chromium-browser", "--remote-debugging-port=9222 --remote-debugging-address=0.0.0.0 --disable-gpu --headless --no-sandbox"]
you should already get only the error messages like this
[0125/175551.930325:ERROR:bus.cc(397)] Failed to connect to the bus: Failed to connect to socket /var/run/dbus/system_bus_socket: No such file or directory
DevTools listening on ws://0.0.0.0:9222/devtools/browser/a388e2a6-5cb3-4aca-bd84-22234cfa3296
[0125/175551.949498:ERROR:sandbox_linux.cc(378)] InitializeSandbox() called with multiple threads in process gpu-process.
Maybe it could already work? Please try it and let me know.
However, it could also mean that the dbus configuration in this image is not ready for this.

Thank you, man! It worked!

It works fine on my local Mac, but I still have some errors after creating container on Linode (Ubuntu 20.04)
Looks like it's somehow related to this bug
[0126/151551.316875:ERROR:file_io_posix.cc(144)] open /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq: No such file or directory (2)

[23:115:0126/151553.941299:ERROR:chrome_browser_main_extra_parts_metrics.cc(230)] END: ReportBluetoothAvailability()

I'm glad it's working.
I'm not familiar with the other errors, but they could be related to the bug you've mentioned, I suppose.
However, it's also true, that the Chromium Browser inside Docker containers always has some limitations and issues. Sometimes you can simply ignore some error messages if they do not do much harm.
It can also be, than some libraries are missing. I try to keep the images as small as possible, so most of stuff is "minimized". You can always add more libraries the standard way. Or you could build a "fat" image by setting the environment variable FEATURES_BUILD_SLIM=0
.
Also make sure that you have enough shared memory in the container. Use at least 256MB, it can help. I've described it by the issue #20.

I've found that removing --headless
causes this bug. Guys in this thread saying that this bug is fixed in Chromium 98.0.4758.9, so, I guess, we must just wait until it's released in public.
I tried different configuration, don't think that something is wrong with you image, I had same result everywhere I tried
from ubuntu-vnc-xfce-g3.
That's actually a good news, thanks. :) I always publish new images on Docker Hub as soon as newer Chromium versions are available, so it'll be solved soon, hopefully.

@accetto looks like it's Chromium 98 released. Could you please update your image, so we can check if headless
bug is resolved?
from ubuntu-vnc-xfce-g3.
@IvanMMM Sorry, I've missed your entry. :(
The version 98 is not yet available in the Ubuntu repositories.
The latest version there is still 97.0.4692.71-0ubuntu0.18.04.1
.
I'll update the image when the newer will be available.
