kroki v0.1.0

Dev tools

Kroki — a unified API that turns text into diagrams: PlantUML, Graphviz, Mermaid, BPMN, Excalidraw, and 20+ more, from a single HTTP endpoint. Deployed as a stateless host-networked Nomad service; embed diagrams in your wikis and docs (docmost, wiki.js, hedgedoc).

kroki

Kroki — a unified API that turns text into diagrams: PlantUML, Graphviz, Mermaid, BPMN, Excalidraw, and 20+ more, from a single HTTP endpoint.

Stateless host-networked Nomad service. Pairs with the docmost, wikijs, and hedgedoc packs (all can point at a Kroki server for diagrams).

Deploy

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

Configure

Variable Default Description
port 8125 HTTP API port (MICRONAUT_SERVER_PORT).
image yuzutech/kroki:latest Container image. Pin a tag in production.
resources { cpu = 500, memory = 512 } Task resources. 
curl http://<node-ip>:8125/graphviz/svg -d 'digraph { a -> b }'

The core image covers PlantUML/Graphviz/Mermaid/etc.; BPMN and Excalidraw need companion containers (add them if needed). Stateless — no volume.
