PaperDockerBuilder

Jenkins pipeline to build a Docker image of Paper.

Dockerfile  # used to build the Docker image
Jenkinsfile # the pipeline file
Readme.md   # you are reading this file
run.sh      # entrypoint of the Docker image

Pipeline process

1. Fetches the information about the latest build of Paper for the provided MC version, from the PaperMC API
2. Downloads the Paper jar file.
3. Builds the docker image with the downloaded jar and the entrypoint script, ensuring libraries are downloaded and Paper patch is applied.
4. Pushes the image to the container registry with the tags $mc_version (e.g. 1.20.1) and $mc_version-$paper_build (e.g. 1.20.1-196)
