Cypress in docker fails to run with read-only project dir

[varac]

Current behavior

Currently, when using the cypress/included docker image and mounting a project dir read-only, cypress fails to run.

Desired behavior

It should not fail and run the tests. It could issue a warning that it is not able to save screenshots or videos.

Test code to reproduce

❯ docker run --rm -it -v $PWD:/e2e:ro -w /e2e cypress/included:10.2.0
libva error: vaGetDriverNameByIndex() failed with unknown libva error, driver_name = (null)
[213:0624/072239.698161:ERROR:sandbox_linux.cc(377)] InitializeSandbox() called with multiple threads in process gpu-process.
[213:0624/072239.700359:ERROR:gpu_memory_buffer_support_x11.cc(44)] dri3 extension not supported.
EROFS: read-only file system, access '/e2e'
Error: EROFS: read-only file system, access '/e2e'

Cypress Version

10.2.0

Interestingly, this seems to only happen in docker. Running is locally (installed with npm) leads to the desired result:

❯ touch /tmp/cytest/de
touch: cannot touch '/tmp/cytest/de': Permission denied

❯ ./node_modules/.bin/cypress run -P /tmp/cytest 
This folder is not writable: /tmp/cytest

Writing to this directory is required by Cypress in order to store screenshots and videos.

Enable write permissions to this directory to ensure screenshots and videos are stored.

If you don't require screenshots or videos to be stored you can safely ignore this warning.
Warning: We failed to trash the existing run results.

This error will not alter the exit code.

The use-case is that I want to run cypress in kubernetes, and the project dir is mounted from a readonly configmap.

[hai-le-niteco]

I'm encountering this too. Desperately looking for a fix

[Tigatok]

Encountering this in a gitlab pipeline, also see the error is related here as well: https://github.com/cypress-io/cypress/issues/23326

Similar errors displayed here, with Kubernetes. Surprisingly, the tests are working fine. And I managed to remove the ALSA errors, but not yet the "libva error". But I wish Cypress would not display "This folder is not writable" in quiet mode...

I have this problem too, on Cypress version 12.17.4
