Scanning Information
The scanner saves your required images and scans all the file system and installed packages.
It scans all the image layers and handles archive files in the layers based on the value in the property 'archiveExtractionDepth'.

The Docker image is saved to the temporary directory defined in your environment and is deleted immediately after the scan.
The scanning results are presented in a new WhiteSource project identified by the name of the image in the following format:  <image id> <repository> <tag>.
The project is created in the WhiteSource product specified in the configuration file or command line.
