Summary

Replaces the "Coming soon." placeholder at openhands/usage/agent-canvas/backend-setup/docker.mdx with a full walkthrough for building a custom Agent Server image and using it as an Agent Canvas backend.

The guide covers:

  1. Build a custom imageFROM ghcr.io/openhands/agent-server:latest-python, adding the JDK, Maven, and common utilities on top.
  2. Run the imagedocker run with a generated SESSION_API_KEY, plus a curl health check and safety guidance for exposing the port.
  3. Add the backend to Agent CanvasManage Backends → Add Backend, paste the URL + API key, mark it as Local, and switch to it as the active backend.
  4. Updating the image — pull a newer base, rebuild, restart, keep the same backend entry.

Includes cross-links to the related guides:

Replace the placeholder Docker backend page with a full walkthrough:
build a custom Agent Server image (FROM ghcr.io/openhands/agent-server,
add JDK + utilities), run it locally with a SESSION_API_KEY, and
register it as a backend in Agent Canvas.
