This produces a 75 MB binary, which can be further reduced to 27 MB with the upx binary packer.

If you want to run the glibc binary on Alpine, you need to:

apk add gcompat libstdc++ fontconfig ttf-dejavu ttf-liberation

The puml files processed in the configuration generation phase should cover as many of the PlantUML features as possible, so that the configuration files contain everything necessary. The repo https://github.com/coni2k/PlantUML seems to be good for this.
