EXAMPLE

67                $ apptainer inspect ubuntu.sif
68
69                If you want to list the applications (apps) installed in a container (located at
70                /scif/apps) you should run inspect command with --list-apps <container-image> flag.
71                ( See https://sci-f.github.io for more information on SCIF apps)
72
73                The following environment variables are available to you when called
74                from the shell inside the container. The top variables are relevant
75                to the active app (--app <app>) and the bottom available for all
76                apps regardless of the active app. Both sets of variables are also available during development (at build time).
77
78                ACTIVE APP ENVIRONMENT:
79                    SCIF_APPNAME       the name for the active application
80                    SCIF_APPROOT       the installation folder for the application created at /scif/apps/<app>
81                    SCIF_APPMETA       the application metadata folder
82                    SCIF_APPDATA       the data folder created for the application at /scif/data/<app>
83                      SCIF_APPINPUT    expected input folder within data base folder
84                      SCIF_APPOUTPUT   the output data folder within data base folder
85
86                    SCIF_APPENV        points to the application's custom environment.sh file in its metadata folder
87                    SCIF_APPLABELS     is the application's labels.json in the metadata folder
88                    SCIF_APPBIN        is the bin folder for the app, which is automatically added to the $PATH when the app is active
89                    SCIF_APPLIB        is the application's library folder that is added to the LD_LIBRARY_PATH
90                    SCIF_APPRUN        is the runscript
91                    SCIF_APPHELP       is the help file for the runscript
92                    SCIF_APPTEST       is the testing script (test.sh) associated with the application
93                    SCIF_APPNAME       the name for the active application
94                    SCIF_APPFILES      the files section associated with the application that are added to
95
96
97                GLOBAL APP ENVIRONMENT:
98
99                    SCIF_DATA             scif defined data base for all apps (/scif/data)
100                    SCIF_APPS             scif defined install bases for all apps (/scif/apps)
101                    SCIF_APPROOT_<app>    root for application <app>
102                    SCIF_APPDATA_<app>    data root for application <app>
103
104                To list all your apps:
105
106                $ apptainer inspect --list-apps ubuntu.sif
107
108                To list only labels in the json format from an image:
109
110                $ apptainer inspect --json --labels ubuntu.sif
111
112                To verify you own a single application on your container image, use the --app <appname> flag:
113
114                $ apptainer inspect --app <appname> ubuntu.sif
