GoSu
A simple Go-based tool to step down from root and execute a process as another user, designed for Docker containers.
What is GoSu?
gosu is a simple Go-based command-line tool that allows a process to step down from root to a non-privileged user and execute another program. It solves the TTY and signal-forwarding issues common with `su` and `sudo`, making it ideal for Docker container entrypoints where clean user switching is required.
Docker container developers and system administrators who need to run processes as non-root users inside containers while avoiding the complexities of `su` or `sudo`.
Developers choose gosu for its simplicity, reliability, and direct integration with Docker's user management. It provides a lightweight, secure alternative for user switching in containerized environments without unnecessary overhead.
