> Would it be useful to save space by sharing layers by having one image from
> another? 🤔 Something like the *java11-ubuntu as the "base" with r and python
> variants FROM that and the r-python being FROM, probably, the larger one of
> those?
> Rough example Dockerfiles
> {code:java}
> FROM eclipse-temurin:11-jre-focal
> # user stuff, install common deps, etc
> ...
> # download/extract spark (maybe keeping python and R files too? they seem
> relatively small compared to the rest)
> {code}
> {code:java}
> # other images in separate Dockerfiles
> FROM spark:3.3.0-scala2.12-java11-ubuntu
> # get "/opt/spark/{python,R}/" contents if not kept in base
> # install python or R (and things like R_HOME)
> {code}
