Struggling to run radiosonde_auto_rx in docker as non root user.

[wuftymerguftyguff]

Hi,

Iam trying to run using a non root user.

The container seems to run the auto_rx.py as user root,

So all files in the log dir get mounted as a volumes created as root.

Trying to pass in UID:GID in the docker run command is not working.

is it possible to modify the Dockerfile to allow the UID:GID to pass through?

Can you explain more about the issue you are encountering when running as per the instructions here: https://github.com/projecthorus/radiosonde_auto_rx/wiki/Docker

You do not need to use sudo or be a root user to start the docker image, and while the log files may be owned by root, you should still be able to read them.

The docker container runs fine and works well if used as documented, but just as it is advised that auto_rx should not run as root if it run outside a container it should also ideally not run as root inside a container.

Docker will run apps in a container as root by default, but it is far from ideal and is not accepted a best practice for production containers.

I should be able to choose to run the app in a container by specifying --user UID in the docker run command, if I do that the contaier breaks because python is not available to non root user inside the container.

I suppose this is really a feature request rather bug.

I'm not really sure how this works without modifying the Dockerfile, and how it would work with us providing pre-built images. @snh might be able to provide some advice.

Running as root lets us bypass a lot of the challenges we'd face with permissions to the USB bus if we run as a non root user.

That said we should be able to update the Dockerfile to accommodate using a specified UID and GID for advanced users who can take care of sorting out any USB bus permissions issues.
