About

The LIP Computing Group has developed udocker.

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 has reached TRL8 and belongs to the catalog of services for EOSC-Hub. Development of new features is taking place in the framework of DEEP-Hybrid-Datacloud.

Download

Udocker may be downloaded from the indigo-datacloud Github repository at:
