I was looking at the available Logstash docker images and it looks like there are alpine-based versions available for the 5.x version tree, but not for the 6.x version tree. Are there plans to make Alpine versions available for the 6.x version tree?
Note that image size isn't my only concern. Using a slimed-down OS on the image also significantly reduces the security vulnerability surface area, thus significantly reducing the chances of a vulnerability slipping in. For this reason, security-sensitive environments/users often prefer to use alpine (or similar) base images.
