2.6. Understanding the UBI micro images
The ubi-micro is the smallest possible UBI image, obtained by excluding a package manager and all of its dependencies which are normally included in a container image. This minimizes the attack surface of container images based on the ubi-micro image and is suitable for minimal applications, even if you use UBI Standard, Minimal, or Init for other applications. The container image without the Linux distribution packaging is called a Distroless container image.
