Summary

This repo demonstrates a lightweight docker able to run the popular Java diagramming tool plantuml.

How to use

• Build the image locally or pull it from DockerHub, then run then container
• Copy the input plantuml diagram from the host to the running container, using the command docker cp. This should look like docker cp src/diagram.iuml 3689309baac3:/usr/local where 3689309baac3 is the container ID.
• Inside the container, run plantuml diagram.iuml to generate the output figure diagram.png
• Copy the output figure from the container to the host, e.g. docker cp 3689309baac3:/usr/local/diagram.png .

Architecture

The docker builds on top of a tiny Alpine Linux Image and provides a minimalistic Java Runtime Environment tailored to running the plantuml tool.
