/scif/apps) you should run inspect command with --list-apps <container-image> flag.
( See for more information on SCIF apps)

The following environment variables are available to you when called
from the shell inside the container. The top variables are relevant
to the active app (--app <app>) and the bottom available for all
apps regardless of the active app. Both sets of variables are also available during development (at build time).

SCIF_APPNAME the name for the active application
SCIF_APPROOT the installation folder for the application created at /scif/apps/<app>
SCIF_APPMETA the application metadata folder
SCIF_APPDATA the data folder created for the application at /scif/data/<app>
SCIF_APPINPUT expected input folder within data base folder
SCIF_APPOUTPUT the output data folder within data base folder

SCIF_APPENV points to the application’s custom file in its metadata folder
SCIF_APPLABELS is the application’s labels.json in the metadata folder
SCIF_APPBIN is the bin folder for the app, which is automatically added to the $PATH when the app is active
SCIF_APPLIB is the application’s library folder that is added to the LD_LIBRARY_PATH
SCIF_APPRUN is the runscript

To list all your apps:

$ apptainer inspect --list-apps ubuntu.sif

To list only labels in the json format from an image:

$ apptainer inspect --json --labels ubuntu.sif

To verify you own a single application on your container image, use the --app <appname> flag:

$ apptainer inspect --app <appname> ubuntu.sif
