plantuml v0.1.0

Dev tools

PlantUML Server — a web service that renders UML and other diagrams from PlantUML text, with a live in-browser editor. Deployed as a single stateless host-networked Nomad service.

nomad-pack run plantuml --registry nomploy

…or one line (add registry + run)

curl -fsSL https://packs.nomploy.com/install.sh | sh -s -- plantuml

Needs nomad-pack on PATH. The script only adds the nomploy registry and runs this pack.

Readme

plantuml

PlantUML Server — a web service that renders UML and other diagrams from plain PlantUML text: sequence, class, activity, component, state, ER, mind-map, Gantt and more. It ships a live in-browser editor and a stable image URL API, so wikis, docs and chat tools can embed diagrams that render on demand.

Single stateless host-networked Nomad service (no volume).

Deploy

nomad-pack registry add nomploy https://github.com/Nomploy/nomad-packs
nomad-pack run plantuml --registry=nomploy

Configure

Variable	Default	Description
`port`	`8080`	Web UI / API port. Fixed at `8080` inside the Jetty image.
`image`	`plantuml/plantuml-server:jetty`	Container image. Pin a tag in production.
`resources`	`{ cpu = 500, memory = 512 }`	Task resources. The JVM needs some headroom.

Open http://<host>:8080 for the editor, or POST/GET encoded diagrams at /svg/…, /png/…, /txt/…. Being stateless, it needs no storage and scales horizontally. Pairs well with wikis like wikijs or hedgedoc.
