Let us take an example of release AthAnalysis,2.2.115 under /cvmfs/unpacked.cern.ch/registry.hub.docker.com/atlas/

lxplus$ apptainer exec -c /cvmfs/unpacked.cern.ch/registry.hub.docker.com/atlas/athanalysis:21.2.115 bash
Apptainer> ls /home/atlas
release_setup.sh
Apptainer> source /home/atlas/release_setup.sh
Configured GCC from: /opt/lcg/gcc/8.3.0-cebb0/x86_64-centos7/bin/gcc
Taking LCG releases from: /opt/lcg
Taking Gaudi from: /usr/GAUDI/21.2.115/InstallArea/x86_64-centos7-gcc8-opt
Configured AthAnalysis from: /usr/AthAnalysis/21.2.115/InstallArea/x86_64-centos7-gcc8-opt
[bash][yesw AthAnalysis-21.2.115]:~ >

That is, start the wanted container, then source /home/atlas/release_setup.sh.

Containers on Docker Hub

The Docker hub hosts the largest container images. You can input keyword to search on the hub. For example, you can put a keyword atlas/ under the search field as shown below:

• A screenshot of searching for Atlas/ on the Docker Hub:

Click on the found container, it will provides the pull command instruction and sometimes also a brief description.

Containers on Other Registries

Apptainer can pull images from any OCI-compliant registry, such as the GitHub Container Registry (ghcr.io) or the CERN GitLab registry (gitlab-registry.cern.ch), using the docker:// or oras:// prefix. See Support for Docker and OCI Containers for more details.
