PlantUML Server

Build Status Docker Pull PlantUML Server is a web application to generate UML diagrams on-the-fly.

To know more about PlantUML, please visit http://plantuml.com/.

Requirements

  • jre/jdk 1.6.0 or above
  • apache maven 3.0.2 or above

How to run the server

Just run:

mvn jetty:run

The server is now listing to http://localhost:8080/plantuml. In this way the server is run on an embedded jetty server.

You can specify the port at which it runs:

mvn jetty:run -Djetty.port=9999

How to run the server with Docker

You can run Plantuml with jetty or tomcat container

docker run -d -p 8080:8080 plantuml/plantuml-server:jetty
docker run -d -p 8080:8080 plantuml/plantuml-server:tomcat

The server is now listing to http://localhost:8080.

How to set PlantUML options

You can apply some option to your PlantUML server with environement variable.

If you run the directly the jar, you can pass the option with -D flag

java -D THE_ENV_VARIABLE=THE_ENV_VALUE -Djetty.contextpath=/ -jar target/dependency/jetty-runner.jar target/plantuml.war

or

mvn jetty:run -D THE_ENV_VARIABLE=THE_ENV_VALUE -Djetty.port=9999

If you use docker, you can use the -e flag:

docker run -d -p 8080:8080 -e THE_ENV_VARIABLE=THE_ENV_VALUE plantuml/plantuml-server:jetty

You can set all the following variables:

  • PLANTUML_LIMIT_SIZE
    • Limits image width and height
    • Default value 4096
  • GRAPHVIZ_DOT
    • Link to 'dot' executable
    • Default value /usr/local/bin/dot or /usr/bin/dot
  • PLANTUML_STATS

Alternate: How to build your docker image

This method uses maven to run the application. That requires internet connectivity. So, you can use following command to create a self-contained docker image that will "just-work".

Note: Generate the WAR (instructions further below) prior to running "docker build"

docker image build -t plantuml-server . 
docker run -d -p 8080:8080 plantuml-server

The server is now listing to http://localhost:8080/plantuml.

You may specify the port in -p Docker command line argument.

How to generate the war

To build the war, just run:

mvn package

at the root directory of the project to produce plantuml.war in the target/ directory.
