Add seleniarm/standalone-chromium support for WebDriver

[DmitriyYukhanov]

Hey, I'm here with a feature request.

Now, as we have an ARM64 Docker Selenium images for standalone chromium, it would be great to add support for this in order to be able to use WebDriver on rPi devices, if possible ^^

@DmitriyYukhanov just change

changedetection.io/docker-compose.yml

Line 40 in c55bf41

# image: selenium/standalone-chrome-debug:3.141.59

to use image: seleniarm/standalone-chromium does it work? please tell me if you get it to work (I dont own a rPi so I cannot test)

if it does work, it just needs to go in as a comment I think

please tell me if you can get it to work.

Thanks @dgtlmoon it installed and started just fine on rPi 4:

pi@raspberrypi:~/ChangeDetection $ docker-compose up -d
Creating changedetection.io               ... done
Creating changedetection_browser-chrome_1 ... done

But it seems some further configuration is required, as I'm seeing "Content fetcher 'html_webdriver' did not respond." error at the web ui when trying to switch the Fetch Method. But I don't see anything which could help at the Fetching pages with WebDriver wiki page..

@DmitriyYukhanov try to help me out a bit here, assume that I'm not infront of your computer, and that I cant access your computer, and I cannot guess what's going on... I need more logs and other information

docker logs changedetection_browser-chrome_1 

or maybe

docker logs browser-chrome

attach it all here (as text, not a screenshot)

[DmitriyYukhanov]

Ah, seems CPU architecture mismatch =/
docker logs changedetection_browser-chrome_1 output:

pi@raspberrypi:~/ChangeDetection $ sudo docker logs changedetection_browser-chrome_1
standard_init_linux.go:228: exec user process caused: exec format error
(same multiple times)

And this container is keeping restarting with this error.
There are no other chromium containers or images installed, not sure what could go wrong with that image =(

[DmitriyYukhanov]

That's because I'm on non-64 bit armv7 =(

Linux raspberrypi 5.10.63-v7l+ #1459 SMP Wed Oct 6 16:41:57 BST 2021 armv7l GNU/Linux

[dgtlmoon]

So there's nothing I can do here...

[dgtlmoon]

The seleniarm doesnt support your platform

[DmitriyYukhanov]

Yeah, seems so =(
I could try with 64 bit Raspberry Pi OS beta version, but it's still in beta and I'm afraid it would take too much time to reconfigure everything I have on rPi after OS reinstall, so it seems I'll stick with current set up for some time.

Thanks for trying to help!

@dgtlmoon

Just to add up: I was able to compile armhf images locally, and it works just fine, yey!

To run with local image all I needed to change in docker-compose.yml is just replacing image: local-seleniarm/standalone-chromium:latest

is there any workaround here? seems compiling the repo gives me a lot of errors so stuck on this one.
