Hi Ismael, In my pursuit of a lightweight base image, I initially considered Alpine and Distroless
1. The next best option I explored is the Ubuntu Docker image( https://hub.docker.com/_/ubuntu/tags) which is a more complete image. It has a size of 70MB compared to the 15MB of the Alpine image (post-installation of glibc and bash), resulting in a difference of 55MB. 2. To assess performance, I executed produce/consume performance scripts on the Kafka native Docker image using both Alpine and Ubuntu, and the results indicated comparable performance between the two. I wanted to check if there's any other image you'd like me to assess for consideration. Your input would be greatly appreciated.
