I noticed one Dockerfile was pinned to 1.4; given that there's a
backward compatibility guarantee on the stable syntax, the general
recommendation is to use
dockerfile:1
, which makes sure that thelatest stable release of the Dockerfile syntax is pulled before
building.
While changing, I also made some minor changes to some Dockerfiles
to reduce some unneeded layers.
