draw.io (diagrams.net) is a client-side diagramming app. It has no user
model and no server-side state (diagrams live in the browser or cloud
storage), so this is the first package to use the Cloudron
authentication-proxy pattern: httpAuth.type=proxy gates access at the
platform edge — the admin restricts who can reach it and the browser
challenges for Cloudron credentials.
- Wraps the official jgraph/drawio:24.7.17 Tomcat image (pinned, verified)
- No database / no persistent storage; installs curl for the health check
- HTTP port 8080, health check on /
- Validated: docker build + run return HTTP 200, container healthy
Gardening: STATUS/README/JOURNAL updated (8/~57 packaged); new
"official-image wrapper + auth proxy" pattern documented in JOURNAL.
