plantuml-server-docker

Provides a PlantUML server docker image that uses GraphViz 2.38.0 as a dependency. Made to circumvent issues with PlantUML and newer versions of GraphViz. There is https://github.com/plantuml/plantuml-server but as of 2020-10-29 they also suffer from the known issues. This image downloads the plantuml-server release from github and deploys it into a jetty-runner.
