If you have docker installed you can use the various docker files as below:
Dockerfile This is the default file I use with my CI tool to generate the docker image AFTER a successful JAR build and test. It takes the jar file as an argument.
Dockerfile-arm This is the same as Dockerfile except it will build an ARM image. Not all arm devices are supported here.
Dockerfile-build This docker file can be used if you want to build from scratch without installing Java. It will download the source files and everything needed to build the application and generate an image. You can download this one file and run
docker build -f Dockerfile-build -t dlmcpaul/solar:test .
Dockerfile-builder This docker file will download the jar file from Github and build an image. It takes the version you want as an argument. So instead of building from source you can create your own container from the released jar
docker build -f Dockerfile-builder --build-arg VERSION=0.26 -t dlmcpaul/solar:test2 .
Dockerfile-google Similar to the default Dockerfile but uses the Google base image for java support
Dockerfile-slimmed This is an experimental Dockerfile where I look at building smaller images using various techniques.
