udocker is a basic user tool to execute simple docker containers in user space without requiring root privileges. Enables download and execution of docker containers by non-privileged users in Linux systems where docker is not available. It can be used to pull and execute docker containers in Linux batch systems and interactive clusters that are managed by other entities such as grid infrastructures or externally managed batch or interactive systems.
udocker does not require any type of privileges nor the deployment of services by system administrators. It can be downloaded and executed entirely by the end user.
udocker is a wrapper around several tools to mimic a subset of the docker capabilities including pulling images and running containers with minimal functionality.
