with the image determined by the flags you pass. By default, they will be shown in
plain text. If you would like to list them in json format, you should use the --json flag.

--app="" inspect a specific app

-d, --deffile[=false] show the Apptainer definition file that was used to generate the image

-e, --environment[=false] show the environment settings for the image

-h, --help[=false] help for inspect

-H, --helpfile[=false] inspect the runscript helpfile, if it exists

-j, --json[=false] print structured json instead of sections

-l, --labels[=false] show the labels for the image (default)

--list-apps[=false] list all apps in a container

-r, --runscript[=false] show the runscript for the image

-s, --startscript[=false] show the startscript for the image

-t, --test[=false] show the test script for the image


$ apptainer inspect ubuntu.sif

If you want to list the applications (apps) installed in a container (located at
/scif/apps) you should run inspect command with --list-apps <container-image> flag.
( See https://sci-f.github.io 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).
ACTIVE APP ENVIRONMENT:
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 environment.sh 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
SCIF_APPSTART is the startscript
SCIF_APPHELP is the help file for the runscript
SCIF_APPTEST is the testing script (test.sh) associated with the application
SCIF_APPNAME the name for the active application
SCIF_APPFILES the files section associated with the application that are added to
GLOBAL APP ENVIRONMENT:

SCIF_DATA scif defined data base for all apps (/scif/data)
SCIF_APPS scif defined install bases for all apps (/scif/apps)
SCIF_APPROOT_<app> root for application <app>
SCIF_APPDATA_<app> data root for application <app>
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
