Chalk™ captures metadata at build time, and can add a small 'chalk mark' (metadata) to any artifacts, so they can be identified in production. Chalk can also extract chalk marks and collect additional metadata about the operating environment when it does this.
Using Chalk, you can build a graph connecting people, development, builds and production, so that devops engineers understand what is happening in the development process, and so that developers can understand what is happening in the infrastructure.
You can use Chalk to solve a variety of specific use cases such as:
Many companies and the US Government are now mandating suppliers to provide supply chain statements when delivering software. This how to is an easy button to deliver the software bill of materials (SBOM), code and builds provenance and supports SLSA, Supply-chain Levels for Software Artifacts, level 2 compliance (an emerging supply chain standard) before SLSA level 1 has been mandated. Follow this guidance on our docs site here.
Chalk’s exec command is a powerful feature that allows you to gather runtime information about your applications as they execute. This capability creates a bridge between the build-time metadata collected during insertion operations and the actual runtime behavior of your software. Follow the guidance on our docs site here.
You can deploy Chalk by setting a global alias for Docker and having it call Chalk, so that every build that runs through your build server using Docker, will automatically be 'chalked'. It's a technique that can be combined with chalks ability to deploy tools and configure monitoring, to automatically add security controls and collect information for every application.

All documentation for Chalk is available at https://chalkproject.io/docs/ and is also fully accessible though the command line interface.
We recommend following the getting started guide on our documentation web site. Full documentation is also available directly inside the CLI.
We provide free binary downloads on our release page.
