vboxsf | VirtualBox guest additions for Android

I'm new to Docker so I might not have some of the terminology correct. Inside the container I'm getting a permission denied error on a directory shared with the host. They appear to have matching uid:gid and the permissions host side are 777. The container is not for running in the background.

I'm using the container to run a big series of untrusted programs one at a time each needing the same initial conditions. So I don't think it's feasible to copy stuff into the docker image at build time. I felt the optimal thing to do is copy the programs one at a time to a temp directory on the host and then share that directory with the fresh container for each run. I also need to collect the output from the container-run programs and keep them on the host so I can see how each program's output differs from the others.

I have looked at the following questions/answers:

• Docker: Copying files from Docker container to host
• How to fix docker: Got permission denied issue - successfully used to make docker run as someone other than root
• How do I add a user when I'm using Alpine as a base image? and Setting up a new user - used to create the user and group

I am:

• running docker as an ordinary user uid 1000, gid 1000, also belonging to the group docker
• setting permissions on the shared directory host side to be 777 with uid:gid as 1000:1000 which is the same as the user
• setting the uid and gid inside the container to match uid and gid from the host
• using the Dockerfile to create a uid and gid each of 1000

I read here that If the first argument begins with a / or ~/, you’re creating a bindmount. Remove that, and you’re naming the volume. So I tried both. The bindmount version seems to have the correct uid:gid but is permission denied, the volume version comes out as root:root.

As a newbie it's hard to know what information to share so here's everything I think might be useful:

I try to include_rule but i keep getting errors on the wrong syntax this is my file structure :

I am not sure what I'm doing wrong here. This is the uri task i have:

I'm having a problem concerning the shared clipboard between a Debian 10 Guest and a Windows 10 Host. So far, I have done the following:

sudo apt install build-essential dkms linux-headers-$(uname -r)

insert guest additions go into the folder containing the Guest Additions files and:

sudo sh ./VBoxLinuxAdditions.run

sudo usermod -a -G vboxsf 'raphael'

This seems to work correctly because the screen effectively gets larger and fits the size of the window, however even after enabling the bidirectionnal clipboard in the settings, it doesn't seem to apply these settings and the clipboard isn't shared in any direction.

Any advices on this?

Thanks and have a nice day!
