openlaw/scala-builder repository overview

⁠ Scala/SBT Builder

Docker images for building Scala/SBT projects, with optional ScalaJS support.

Built on top of Alpine Linux with a few tricks to keep things small, and contains a built-in workaround for the docker layer-caching bug in SBT. See the Dockerfile for details.

⁠Installation

1. Install Docker⁠
2. Pull automated build⁠ from public Docker Hub Registry⁠:

docker pull openlaw/scala-builder

⁠Image Variants

⁠openlaw/scala-builder:, openlaw/scala-builder:*-alpine

This is the defacto image. If you are unsure about what your needs are, you probably want to use this one. It is designed to be used both as a throw away container as well as the base to build other images off of.

⁠openlaw/scala-builder:*-node

Extends the base image with a LTS version of Node.js which is a build environment dependency for ScalaJS projects.

Note that while this image contains Node.js, it is provided strictly as a dependency of ScalaJS, and should never be used as a base image for node projects. (For actual node projects, use an official node image as the builder for much better results).

⁠Usage

$ docker run -it --rm openlaw/scala-builder

By default the WORKDIR is set to /src, so if you want to mount local code you can do something like:

docker run --rm -v $(pwd):/src openlaw/scala-builder sbt compile
