delete sandbox

[jammywwh]

Hi,
As a user, the administrator has granted me the build permission of singularity.
After I used the following command to build the sandbox,
I wanted to delete the folder where this sandbox is located, but I found that this folder belongs to root and I don't have the permission to delete it. What should I do?

sudo singularity build --sandbox ./tempDir annotsv.def
sudo rm -rf ./tempDir

It is expected that this folder (./tempDir) can be deleted.
Actual behavior: Permission denied

Hello. This issue has been converted to a discussion as it is a question around usage, rather than a bug in SIngularity.

I'm not clear exactly what permission you have been granted? Has the administrator only allowed you to run singularity build with sudo - or have you been permitted to run all commands?

If you are not allowed to run rm with sudo then its expected you cannot remove the directory. By running the build with sudo it will always be owned by root.

You may be able to partly get around this by:

1. Running the build with sudo, to create a .sif file
2. Converting the .sif file into a sandbox as your own user, without sudo.

sudo singularity build temp.sif annotsv.def
singularity build -s ./tempDir annotsv.def

The .sif file would still be owned by root, but the sandbox would then be owned by your user account.

For the best advice it's better to give full information about what you are trying to acheive. What is the workflow that you are trying to follow? Why do you need a sandbox?
