[3 Jun 2026] Apptainer Module No Longer Sets APPTAINER_BINDPATH

The apptainer module (module load apptainer) no longer automatically sets the APPTAINER_BINDPATH environment variable. If your Apptainer containers rely on this variable to bind host paths (e.g. /rhome, /bigdata), they may fail to find expected files.

To fix this, explicitly pass bind paths using the --bind flag when running your container:

apptainer exec --bind /rhome,/bigdata my_container.sif my_command

Alternatively, you can set APPTAINER_BINDPATH yourself before running Apptainer:

export APPTAINER_BINDPATH=/rhome,/bigdata
apptainer exec my_container.sif my_command

If you continue to experience issues, please contact us at support@hpcc.ucr.edu or via Slack.
