Hi Justine, Thanks for the feedback. I have added the above comparison results to the KIP.
Given the widespread use of Alpine, the likelihood of encountering issues is minimal. Ubuntu, being a more comprehensive image, is expected to be lesser prone to such challenges. Considering that we are initially releasing a GraalVM-based Docker image for local usage, I am inclined to prioritise minimising its size, which can be achieved by using the Alpine image. Should future instances suggest the need for a different Docker base image for optimisation, we can explore alternatives at that time.
