Chainguard isn't your average security platform—it's the first developer platform specifically designed to fortify your software supply chain, ensuring that every line of code you ship is as secure as can be.
Recently, I had the privilege of embarking on a collaborative journey with Chainguard. They approached me with an invitation to test and explore their platform, leading to the creation of a sponsored video. This collaboration provided an invaluable opportunity to delve deep into Chainguard's offerings and witness firsthand the transformative impact it can have on development workflows.
In this video, we'll explore why Chainguard is a game-changer for developers everywhere. From understanding the critical need for software security to unveiling the powerful features of Chainguard, you'll learn how this tool can empower you to ship software with confidence.
Join me as we peel back the layers of software security and discover how Chainguard is transforming the way developers approach security. Don't miss out on this insightful journey into the heart of secure software development!
Chainguard Images are a collection of container images designed for security and minimalism.
Many Chainguard Images are distroless; they contain only an open-source application and its runtime dependencies. These images do not even contain a shell or package manager. Chainguard Images are built with Wolfi, our Linux undistro designed from the ground up to produce container images that meet the requirements of a secure software supply chain.
The main features of Chainguard Images include:
Minimalist design, with no unnecessary software bloat
Automated nightly builds to ensure Images are completely up-to-date and contain all available security patches
High quality build-time SBOMs (software bill of materials) attesting the provenance of all artifacts within the Image
Verifiable signatures provided by Sigstore
Reproducible builds with Cosign and apko (read more about reproducibility)
Chainguard Images are available from the Chainguard Registry and can be pulled from cgr.dev. You can review images files on GitHub and can find complete lists of available Chainguard Images in the public Images Directory or within the Chainguard Console.
Why Minimal container images
The fewer dependencies a given piece of software uses, the lower likelihood that it will be impacted by CVEs. By minimizing the number of dependencies and thus reducing their potential attack surface, Chainguard Images inherently contain few to zero CVEs. Chainguard Images are rebuilt nightly to ensure they are completely up-to-date and contain all available security patches. With this nightly build approach, our engineering team sometimes fixes vulnerabilities before they’re detected.
Note that there is often a -dev variant of each Chainguard Image available. For example, the -dev variant of the mariadb:latest Image is mariadb:latest-dev. These images typically contain a shell and tools like a package manager to allow users to more easily debug and modify the image. We recommend for production environments that you use Chainguard’s -dev Images in a multi-stage Docker build; this will allow you to use a -dev variant image as a builder container, and then promote that build to an image that removes anything unnecessary.
Let's secure our software supply chains and build a safer digital future together with Chainguard! Thanks for watching!
