GlueX and Containers
From GlueXWiki
Contents
Categories of Containers
The container world is not monolithic, so we have to define some terms.
Container Types
There are three types: Docker, Singularity, and Shifter
For Singularity there are two sub-types: Sandbox and Singularity Image Format (SIF)
Installed Software Levels
There are three levels: raw, gluex-prereqs, and gluex-software
Group Binding Styles
There are two styles for binding /group/halld: system-binds-group (SBG) and user-binds-group (UBG)
Distribution Systems
There are three methods we use for distributing containers: DockerHub, Web, CVMFS.
Container Use at Various Sites
| Site | Category | Distribution System |
|---|---|---|
| NERSC | Shifter/gluex-prereqs/SBG | DockerHub |
| OSG | Singularity(Sandbox)/gluex-prereqs/SBG | CVMFS |
| PSG | Singularity(Sandbox)/gluex-prereqs/SBG | CVMFS |
| Big Red | Singularity(Sandbox)/gluex-prereqs/SBG | CVMFS[?] |
At this writing there is no standard container-use practice at JLab.
