Udocker is a container tool that enables executing Docker containers in user space using chroot, proot, and other user-space mechanisms. This is useful on systems where a full Docker installation is unavailable or where root access is restricted.
Key Features:
- No Root Required: Runs entirely in user space.
- Docker Hub Support: Supports pulling images directly from Docker Hub.
- CLI Command: Once installed, use the
udocker command to interact with it.
Limitations:
- It provides a container-like environment but is limited compared to a full Docker installation.
