We use multistage builds to drop the compressed size of the container down ~70% to ~= 130M using the openjdk alpine base image.

See https://hub.docker.com/r/shadowfiend/hoisted/tags/ for resulting size with latest hoisted. This dockerfile isn't quite ready yet, it's set up for local testing. |
Since the Dockerfile now copies hoisted from the local fs so as to maximize build speed, we need to clone it outside the file.
|
Ok, pushed a tweak to build.sh that clones hoisted outside docker and then removes it post-build, if that sounds okay. Core idea: let the clone happen in the parent fs, then let docker detect when existing intermediate stages line up properly. The new structure should ensure that only a change in build.sbt triggers a full refetch of dependencies (by caching the intermediate stage where we do the dep fetch). |
