Glossary of Terms

  • Command Library: Tern references a database of shell commands to determine what packages got installed. This is called the "Command Library".
  • Report: the artifact produced after running Tern. This is either a text document or a machine readable format.
  • Image: A container image, typically following the OCI image specification
  • Layer: A root filesystem or the difference between a previous filesystem and a new filesystem as created by storage drivers like AUFS or OverlayFS. See the OCI Image Layer specification for a general overview of how layer filesystems are created.
  • Package: A software package or library
  • Notice: A record of an incident that Tern came across during execution
  • Notice Origin: The location from which the Notice came. This can be the container or Dockerfile or Command Library or something in the development environment.
  • Cache: A database that associates container layer filesystems with the packages that were installed on them. Currently this is only represented by a yaml file and some CRUD operations against it.
  • Dockerfile: A file containing instructions to the Docker daemon on how to build a container.
