The Open Container Initiative (OCI) is a Linux Foundation project that aims to design open standards for operating-system-level virtualization, most importantly Linux containers. OCI image format uses the tarball container format and is designed to be portable across various operating systems, hardware, CPU architectures, public clouds, etc. Docker images are also supported in Snyk, with the ability to scan both Docker archive and OCI archives, including multi-architecture images stored in a "fat manifest" that references image manifests for platform-specific versions of an image. Snyk supports scanning Docker images on various platforms, including Linux, Windows, and macOS, by passing the `--platform` flag. The Docker image formats used are Docker archive format (part of the deprecated v1 of the docker image specification) and OCI image format (using tarball container format). Snyk can also provide remediation advice for vulnerabilities found in images.
