There's two way to install plantuml-service:

Get plantuml-service.jar from GitHub releases.

There is a docker image in Docker Hub.

docker pull bitjourney/plantuml-service:1.4.0

Returns an SVG image of the request body, processed by PlantUML.

Because the size of GET requests might be limited by middlewares, the POST API is recommended in production.

Returns an SVG image of :source processed by PlantUML.

:source is source code of PlantUML, encoded in percent encoding.

Example:

Given a PlantUML source code:

@startuml
Alice -> Bob: Authentication Request
Bob --> Alice: Authentication Response

Alice -> Bob: Another authentication Request
Alice <-- Bob: another authentication Response
@enduml

To show it in SVG:

![]($ENDPOINT/%40startuml%0AAlice%20-%3E%20Bob%3A%20Authentication%20Request%0ABob%20--%3E%20Alice%3A%20Authentication%20Response%0A%0AAlice%20-%3E%20Bob%3A%20Another%20authentication%20Request%0AAlice%20%3C--%20Bob%3A%20another%20authentication%20Response%0A%40enduml%0A)

Then, you'll get:

This path takes multiple config parameters to set configuration, for example:

/svg/...?config=scale max 1024 width&config=skin BlueModern

NOTE: you should use server-side RPC to render SVG because browsers have URL limitations.

Shows the version of PlantUML and plantuml-service in JSON:

{"PlantUML":"2017.11","plantuml-service":"1.0.9"}

This is also intended to check the service helth.

Run on local:

./gradlew stage

Here is an example systemd.service(5) config file:

[Unit]
Descrption=PlantUML service
Documentation=https://github.com/bitjourney/plantuml-service
Wants=network-online.target
After=network-online.target

[Service]
ExecStart=$APP_PATH/app/bin/plantuml-service
WorkingDirectory=$APP_PATH/app

User=$APP_USER
Group=$APP_USER

[Install]
WantedBy=multi-user.target

1. Create the credential file by echo "oauth=$GITHUB_ACCESS_TOKEN" > ~/.github
2. Update the version of build.gradle
3. Run ./gradlew release
   • It uploads artifacts to GitHub
   • And then build the docker image and push the image to Docker Hub
