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."
Investigate the feasibility to provide UBI micro based Liberty images
We'll need UBI micro based Java images first. This issue is opened with Java team: https://github.com/ibmruntimes/Semeru-Runtimes/issues/8
