Playwright Support

[cry0genic]

Hey @vital987, thanks for helping with the Selenium Grid Support.

I now want to experiment running this with Playwright.

I tried changing the 5-chromium.conf with:

command=bash -c 'chromium --remote-debugging-port=9225 --no-sandbox --test-type --disable-dev-shm-usage --disable-gpu --start-maximized'

And for Playwright:

async with async_playwright() as p:
                browser = await p.chromium.connect_over_cdp("http://<container-ip>:9225")

However, this configuration is not working and I'm unable to debug the exact problem.

If you can help me with this in anyway, would really appreciate it.

Thanks!

Hey @vital987, following up, do let me know if you can help me out here.

Thanks!

Hey @vital987, just to give more context:

Things I've tried:

1. Bound in docker-compose.yml ("9225:9225") + exposed it in Dockerfile (EXPOSE 9225)
2. Chromium.conf: chromium --remote-debugging-address=0.0.0.0 --remote-debugging-port=9225
3. Checking the stderr_logfile and it says DevTools listening on ws://127.0.0.1:9225/devtools/browser/<some-id>. Once I try connecting via either p.chromium.connect_over_cdp("ws://<container-ip>:9225/devtools/browser/<some-id>") or p.chromium.connect_over_cdp("http://<container-ip>:9225) - I get ECONNRESET or Timeout

Hey @cry0genic , though I dont think you need this now, but Since I had to do something similar I found an answer for you, the problem is chromium --remote-debugging-address=0.0.0.0 --remote-debugging-port=9225 this will not start the port on 0.0.0.0 though you have done everything right, still.
You can verify this by using netstat -tuln inside the docker container using docker exec -it <container name or id> /bin/bash .

So now we have to install socat or something similar like ncat or netcat on our docker to proxy the connection.
A working command with socat will be chromium --no-sandbox --disable-sync --disable-popup-blocking --disable-dev-shm-usage --disable-gpu --start-maximized --force-device-scale-factor=1 --remote-debugging-port=9223 --remote-debugging-address=127.0.0.1 $START_URL & \ socat TCP-LISTEN:9225,FORK TCP:127.0.0.1:9223

@suyash5053, Hi, when you don't use --headless flag , this flag will be ignored --remote-debugging-address=0.0.0.0 , AI said this is for safe. Your code has provided an excellent approach to enabling remote debugging for this project.

@YanchuangJin Thank you for the kind words! I’m glad to hear my solution helped.
