Scala is a JVM-based programming language which marries the functional and object oriented programming paradigms. It is mainly known for its use in the Play and Spark frameworks. This is a Docker image for Scala based on Alpine to get as small an image footprint as possible. Honestly, I don't expect anyone to use this (or any other Scala) image as a base for another image. This image just exists to provide an easy entry into the Scala REPL without having to install it locally.
I would guarantee tags for the latest and the previous patch release in a minor release (along with the minor release as a tag). What that means that for the 2.11 minor release, we would have 2.11.11 and 2.11.12 and 2.11 as tags. latest will always point to the latest Scala release. See the manifest.yml file for more information on the tags.
You can run the REPL for the latest Scala version using.
docker run --rm -it aa8y/scala
For an older/specific version use.
docker run --rm -it aa8y/scala:2.11.11
For running an interactive shell within the container, use this command and specify the required version. You might want to do this when you want to use the Scala compiler, scalac.
docker run --rm -it --entrypoint /bin/bash aa8y/scala:2.10
