Dalec is a project aimed at providing a declarative format for building system packages and containers from those packages.

Our goal is to provide a secure and reproducible way to build packages and containers, with a focus on supply chain security.

• 🐳 No additional tools are needed except for Docker!
• 🚀 Easy to use declarative configuration that provides reproducible builds
• 📦 Build packages and/or containers for Azure Linux 2 and 3 (formerly known as CBL-Mariner)
• 🔌 Pluggable support for other operating systems
• 🤏 Minimal image size, resulting in less vulnerabilities and smaller attack surface
• 🪟 Support for Windows containers
• ✍️ Support for signed packages
• 🔐 Ensure supply chain security with build time SBOMs, and Provenance attestations

👉 To get started, please see Dalec documentation!
