Trouble Using in Alpine Linux (Docker)

[jdholtz]

Hey. I am getting the following error when attempting to run SeleniumBase in Alpine Linux through Docker: FileNotFoundError: [Errno 2] No such file or directory: '/root/.cache/selenium/chromedriver/linux64/117.0.5938.62/chromedriver'.

This file does exist, but when I try to execute it manually, it gives the same error (not found). This appears to be that SB is downloading the file wrong (or for the wrong architecture? - the file command says it is x86_64 though). Is Alpine supported or am I getting this error because Alpine is specifically not supported for this project? I think it would be helpful to people trying to build a minimal Docker image with SB as Alpine Linux saves a lot of space in the final image.

Here is a minimal Dockerfile that reproduces the issue:

FROM python:3.11-alpine

WORKDIR /app

RUN apk update && apk add --no-cache chromium

RUN pip3 install --upgrade pip && pip3 install --no-cache-dir seleniumbase

ENTRYPOINT ["python", "-c", "from seleniumbase import Driver; Driver()"]

SeleniumBase doesn't touch the .cache/ folder... That folder is specific to raw selenium driver & browser downloads. SeleniumBase may try to use existing drivers found on the PATH (which may include .cache/), but if something from there generates errors, then make sure you have the drivers you need already in the seleniumbase/drivers folder.

You can get drivers in there via:

sbase get chromedriver

sbase get uc_driver

As for supported architecture, UC Mode requires non-ARM drivers. ARM is fine for regular Chrome, but UC Mode will need the non-ARM version in order to properly patch the driver.

Also, if you get errors, I'll need to see a more specific stack trace in order to know the exact way an error happened. And I'll need to know the seleniumbase version used.

It actually started working once I downloaded the chromium-chromedriver package on SB 4.18.6. Thank you for the quick response!

As a side note, I am able to use UC with ARM (uname -r: 6.2.10-1-aarch64-ARCH) if I install the above package on Alpine Linux.

hi there @jdholtz or @mdmintz , could you help to share the working dockerfile with the steps required to "download the chromium-chromedriver package'? i recently started working on this (using alpine linux docker image) and found the same issue, previously i tried to run another project which uses ubuntu and had no trouble with it. Thank you so much in advance.

[jdholtz]

In the Docker file, you can change RUN apk update && apk add --no-cache chromium to RUN apk update && apk add --no-cache chromium chromium-chromedriver which fixed it for me.

Here is the Dockerfile of the project I use SeleniumBase for.
