The post-installation script from these packages downloads the image so that the application it contains can be used immediately afterward. All the details for the integration, as well as the instructions for creating or retrieving the Docker image, are in a single YAML file, which, in turn, is packaged in one of the DEB files provided by the Kali project. To weave its magic, Kaboxer uses existing Docker features such as mountpoints and port redirects.
The only reason Docker was chosen first was because its containers come with a large number of parameters for configuration, so images can be integrated easily, both with the host system and across multiple containers. The decision in favor of Docker does not rule out other container formats in the future. You install the packages in the usual way with the sudo apt install command, and the applications are then available in the main menu. To create the DEBs, the Kaboxer team has extended Debian's debhelper packaging tool with the debhelper_kaboxer option and adapted the build system accordingly. During the installation, these packages then download the images. They create Docker images of the applications, which they link with classic Debian packages. The developers emphasize the compatibility of this approach with other Debian variants in the documentation. The Kaboxer framework extends the Debian package system to include containers but integrates them into the existing system and controls them transparently. Kali Linux is based on Debian and uses its package manager. Kaboxer is short for Kali applications boxer. To address these problems, Kaboxer, a Docker and DEB package-based application developed for Kali Linux, which specializes in penetration tests and digital forensics, transparently deploys difficult-to-package applications in Docker containers within the Debian packaging system.
Many of these applications are not available in the Debian repository, and others are difficult to package (e.g., because they expect outdated libraries that virtually no distribution now includes). Sandboxing as a security feature can play a role, or isolating apps so that they do not interfere with other programs.Īdditionally, not all software can be easily packaged and kept up to date with the use of traditional package formats, especially for distributions like Kali Linux that ship hundreds of highly specialized applications. Some approaches allow you to install multiple versions of a program simultaneously. The new package formats (e.g., Flatpak and Snap) are becoming more and more widespread, and for many reasons, containers are becoming increasingly important, even in the everyday lives of average desktop users.ĭevelopers want to see their software reach users more quickly without having to create packages in different formats. The way distributions deliver software is changing.
