Container support in Vac

Published online: 17 September 2019
During 2017 support for Docker and Singularity containers was added to the Vac system, in addition to its long standing support for virtual machines. All three types of "logical machine" can now be run in parallel on the same pool of hypervisors, using container or virtual machine definitions published by experiments. We explain how CernVM-FS is provided to containers by the hypervisors, to avoid any need to operate the containers in privileged modes. Finally we describe how LHCb Docker containers use this model and have been used to validate the Vac implementation.
