New to Singularity 2.4 is the ability to run container “checks” on demand. Checks can be anything from a filter for sensitive information, to an analysis of installed binaries. A few default checks are installed with Singularity and others can be added by the administrator. Users can perform checks at build time or on demand: Perform all default checks, these are the same
$ singularity check ubuntu.img $ singularity check --tag default ubuntu.img
Perform checks with tag “clean”
$ singularity check --tag clean ubuntu.img
What checks are available?¶
Currently, you can view all installable checks here, and we anticipate adding an ability to view tags that are available, along with your own custom checks. You should also ask your administration if new checks have been added not supported by Singularity. If you want to request adding a new check, please tell us!.
