Would it possible to include Dockers Interface in the cloud agents interface

Hey, no problem. The Dockerfile setup is done in .cursor/environment.json in the repo root. The basic structure is:

{
  "build": {
    "dockerfile": "Dockerfile",
    "context": ".."
  },
  "install": "bash .cursor/install.sh",
  "start": "bash .cursor/start.sh",
  "terminals": []
}
  • build.dockerfile is the path to your Dockerfile relative to .cursor/
  • build.context is the build context, usually .. which is the repo root
  • install is the command to install dependencies
  • start is the command to start services
  • terminals is optional, preset terminals that show up in the Cloud Agents window

After you commit .cursor/environment.json and the Dockerfile, the agent will pick up the config and build the environment. Full docs: Cloud Environment Setup | Cursor Docs

If you plan to run Docker inside the agent docker-in-docker, add fuse-overlayfs and iptables-legacy in the Dockerfile, and make sure the cloud agent user has permission to run Docker. That’s covered in the Running Docker section at the same link.

A couple threads with working examples and common gotchas:

Let me know if anything isn’t getting picked up. Share your environment.json and the build log and we can take a look.
