Description

This utility lets you create an executable file, with the suid flag set. The suid flag makes it possible for an user to execute an executable as if they are the owner of the file. For example:

suid-wrapper -o run_docker_sh $(which docker) -- run -it --rm alpine sh --

With the command above, a run_docker_sh will be created. Consider this file is owned by a user named 'docker'. If a user named 'user' tries to run it, because of the suid flag, the process that will be started will have the uid set to that of 'docker', with the same permissions 'docker' has.
