Show metadata for an image
Inspect will show you labels, environment variables, apps and scripts associated 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.
singularity inspect [inspect options...] <image path>
$ singularity 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: $ singularity inspect --list-apps ubuntu.sif To list only labels in the json format from an image: $ singularity inspect --json --labels ubuntu.sif To verify you own a single application on your container image, use the --app <appname> flag: $ singularity inspect --app <appname> ubuntu.sif
--all show all available data (imply --json option) --app string inspect a specific app -d, --deffile show the Singularity recipe file that was used to generate the image -e, --environment show the environment settings for the image -h, --help help for inspect -H, --helpfile inspect the runscript helpfile, if it exists -j, --json print structured json instead of sections -l, --labels show the labels for the image (default) --list-apps list all apps in a container -r, --runscript show the runscript for the image -s, --startscript show the startscript for the image -t, --test show the test script for the image
