Snyk uses Skopeo, Buildah, and Podman command line tools for container scanning, allowing developers easy access to comprehensive security scans of local Docker or OCI images as part of their development workflow, without requiring raised privileges. The use of open standards enables seamless integration with both Docker and OCI-based container registries. Snyk supports saving images in both Docker archive and OCI archive formats, which are supported by Skopeo. Buildah provides a wide range of functionality around building OCI compliant containers and images, while Podman provides for the management and execution of OCI containers. The combination of these tools enables developers to take advantage of host resources during builds, and also allows them to leverage programming language features such as conditionals, loops, or user input during the build process. By using Snyk with Skopeo, Buildah, and Podman, developers can easily scan their local images for known vulnerabilities and weaknesses, ensuring a more secure development workflow.
