This image contains plantuml.
Available on dockerhub as ectoplasm/plantuml
It exposes limited plantuml functionality. You provide as an argument a plantuml file and it will save a .svg and .png file as output.
The easiest way would be to grab the script and add it to /usr/local/bin or elsewhere in your PATH, e.g.
wget https://raw.githubusercontent.com/0x646e78/docker-plantuml/master/plantuml -O /usr/local/bin/plantuml
Then can be used such as plantuml example.puml
If successful both svg & png images will be in out/
I have only enabled svg and png (and you always get both), and single file processing.
No GUI support.
See docker/README.md for further information on using the container.
