Excalidraw - Towbar

Upstream source: Current installation guide. The official image serves only Excalidraw’s browser client. It needs no Datastore or Service volume, but the self-hosted client does not provide Excalidraw’s sharing and live collaboration services.

Configure

Prepare the example server, connect the repository, and map production to the branch containing these manifests. Replace the example server IP and domain. Commit the manifests, then sync the repository and inspect the resolved configuration.
Deploy the Service, then perform the checks below before enabling auto-deploy.

Verify

Create a diagram and export it. Test in another browser before assuming drawings or collaboration are shared across users; this recipe deploys only the client. For field constraints, see Service manifest.
