Fails to spawn browser inside my Docker container app

[MutarIO]

Hello guys,

I have a Docker container app in which I am trying to utilize nodriver in a python script.
However, for some reason it will never start properly.

When I try to spawn a browser (using the no_sandbox=True parameter inside my start function) I get the following error:

`(venv) root@cdee75c0f2bd:/var/www/python# python scraper/nodriver_scraper.py "https://example.com" "body"
Error:
---------------------
Failed to connect to browser
---------------------
One of the causes could be when you are running as root.
In that case you need to pass no_sandbox=True

Traceback: Traceback (most recent call last):

I am already running with no_sandbox=True but this does not help.

If anyone knows a fix, please let me know!

I got everything working with Symfony Panther which also uses the same binary so the installation of Chromium inside my container is not the issue here. I am using the PHP-FPM base image.

Same issue here ..
I even tried to run the docker container with a non-root user

Since when are Docker containers designed to run Gui apps?

Without hacks you can't easily just start a browser

Headless browser for dynamic webscraping is widely used. You need to install some dependencies but you can do it perfectly fine, headless or not.

Any update about this issue please ? It was working fine before but starting from last week the start() method started throwing this error :

I've tried setting sanbox to false, changing user to non-root user, using new user_data_dir, --disable-dev-shm-usage and plenty of other workarounds, but none of them is working.

IS this related to Nodriver or the browser itself ??
