Video recorder stores output as root by default

[borbudak-jadbio]

Docker images run as user/group root by default, and so all files created are owned by root. This can lead to problems when non-root users run the image, as they won't have full ownership of the output. For example, they won't be able to delete the output without sudo privileges.

For logs this can be handled by passing the --user flag when starting selenoid. There is no way to do that for the video recorder (at least I haven't found a way).

I propose either:

• passing the user/group used by selenoid to the video recorder container, or
• adding an additional flag with arguments which are then forwarded to the video recorder container.
