DocF-Sec-Check is a tool designed to enhance the security of Dockerfile commands. It aims to provide security notifications at different levels, including within the Dockerfile itself and in Docker images. Installation is possible via virtualenv, PyPI using pip, building from a Dockerfile, or directly from DockerHub. To use it from a Dockerfile or DockerHub, a local Dockerfile path needs to be specified for scanning. The tool can also be integrated into Python code by importing the DocFChecker class. Contributions and development details are available in the CONTRIBUTING.md file. The project is licensed under GPL-3.0, and support for the developer is welcomed through donations or GitHub Sponsors. The tool helps in identifying and addressing potential security vulnerabilities in Dockerfiles. It is developed and maintained by Osman Kandemir.
