About The Project

• Run docker-runcheck to validate your Dockerfile before attempting time-intensive docker builds.

• docker-runcheck works as follows:

  • contructs one or more containers based on the mentioned image
  • docker image is downloaded if not present but it is not built.
  • export image as tar file and compile a list of the available binaries in the image
  • compile a list of any binaries mentioned in a RUN command that are missing from the image or are used before being installed by a package manager.
