Apache Buildr is a build system for Java-based applications, including support for Scala, Groovy and a growing number of JVM languages and tools.
Some (CI) systems are ready for docker but not so ready for Buildr and its dependencies. This projects aims at building a ready to use docker image so you don't have to. It provides an isolated space for the build process, i.e. you will probably have less troubles if your builds bind to sockets or ports that may be used by others.
| Tag | Buildr | Ruby | JDK |
|---|---|---|---|
| 1.4.20-jruby-jdk7 | 1.4.20 | JRuby 1.17.16 | Java 7 |
| 1.4.20-jruby-jdk8 | 1.4.20 | JRuby 1.17.16 | Java 8 |
When run on Linux Docker runs as root. Thus, all files created by the container belong to root:root. This is a well known Docker limitation, which will hopefully be addressed soon. See Linux-Specific Improvements and Dealing With Root at this page for a workaround.
Currently there are only containers with JRuby and Buildr. Containers for plain rubies may come in future.
The image bundles JRuby with a pre-installed version of buildr and its dependencies. The version is supposed to be the latest, each buildr release should be available via a docker hub tag.
The container can be run in the working folder of the project to build. It needs to be mounted as a docker volume.
docker run --rm -ti -v `pwd`:/workspace vanto/apache-buildr:latest-jruby-jdk7
Note: On non-interactive setups like CI servers remove the -ti.
If you want to use a shared local maven repository, just mount your local .m2 directory into the docker container. This can be achieved by adding -v $HOME/.m2:/root/.m2 to the command above.
Any buildr arguments can be appended and will be passed to buildr. Buildr will operate on the current directory, so you will have immediate access to the build results.
Example:
$ docker run --rm -ti -v `pwd`:/workspace vanto/apache-buildr:latest-jruby-jdk7 clean package test=all
Run docker build --rm -t vanto/apache-buildr:dev . in the respective directory to create a new image, docker rmi vanto/apache-buildr:dev to remove the image. JRuby and Buildr version numbers can be changed in the Dockerfile.
