EXAMPLE¶

  $ 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
