docker-sbt-compiler

A docker container with sbt to compile in a container.

Properites

This container includes:

Alpine OS
Java 1.8
GLIBC 2.25-r0
Scala 2.11.7
SBT 0.13.8

Usage

docker run -it --rm -v "your/project/path:/app"  own3dh2so4/sbt-compiler sbt {sbtOption}

Parameters:

• -it: Keep STDIN open even if not attached. Allocate a pseudo-TTY
• --rm: Automatically remove the container when it exits
• -v: Bind mount a volume
  • "your/project/path" Path where is your project. If you launch the container in the root of your proyect you can use $PWD
  • "/app" is the path where the container search the build.sbt
• own3dh2so4/sbt-compiler Container name
• sbt {sbtOption} SBT command

Caching sbt downloads

Like maven, sbt need libraries that it download the first time it's executed.

The container doesn't include this libraries and your project dependencies. For this reason if you execute the last command, the container will download "all Internet". Probably it's a good idea caching this dependecies in your local host.

In maven this folder is allocated in "user/home/.m2" to sbt the folder is "userhome/.ivy2"

docker run -it --rm -v "$PWD:/app" -v "user/home/.ivy2:/root/.ivy2" own3dh2so4/sbt-compiler sbt {sbtOption}

• -v: Bind mount a volume
  • "user/home/.ivy2" Path where you want to save sbt dependecies
  • "/root/.ivy2" Path where the sbt search the project dependencies

Example

$ docker run -it --rm -v "$PWD:/app" -v "$HOME/.ivy2:/root/.ivy2" own3dh2so4/sbt-compiler:sbt-0.13.8 sbt assembly
