Dockerfile to automate the Spigot Minecraft server build process. You should use this as part of a multistage build to create your own Spigot server containers, or check out my own Spigot server container here.
Upon a successful build, the Spigot binary will be placed in /src/build/spigot/ and can be copied out as part of your server Dockerfile instructions. This has the benefit of only running the server binary in a pure JRE environment, without all the build tools and unnecessary bloat within the container:
FROM kawaii/spigot-builder:1.15.2 as BUILD
FROM openjdk:12-jdk-alpine
COPY --from=BUILD /src/build/spigot/spigot-1.15.2.jar /usr/bin/spigot.jar
... via docker build
This image requires a number of build-time arguments to be passed through. It should be noted that this is not a Spigot server image but rather an image to build a server binary to then be used in other images. The BUILD_AUTHORS and BUILD_DATE arguments are optional and not required to build a working image.
