Daytona Cloud Server
Use this skill when the user needs the hosted/server side of OpenWork running in
Daytona. This is separate from the Electron desktop sandbox.
What This Covers
- Den Web on port
3005.
- Den API on port
8788.
- Worker proxy on port
8789.
- MySQL inside the server sandbox.
- Public Daytona preview URLs for Electron to consume.
- Marketplace, org policy, cloud auth, and server-managed extension flows.
Start Server Sandbox
From the repo root:
bash .devcontainer/test-server-on-daytona.sh [branch-or-commit]
The helper creates a separate server sandbox, starts MySQL, Den API, Den Web,
and worker proxy, waits for health checks, then prints URLs.
If dependencies or the base image changed, refresh the server snapshot:
bash .devcontainer/create-daytona-openwork-server-snapshot.sh
Connect Electron To Server
For end-to-end desktop validation, use the daytona-electron-den skill. This
section only covers wiring the Electron sandbox to the printed server URLs.
Start a second Daytona sandbox for Electron and point it at the server URLs:
bash .devcontainer/test-on-daytona.sh [branch-or-commit] \
--den-base-url <DEN_WEB_URL> \
--den-api-base-url <DEN_API_URL>
For flows that must require cloud sign-in, add --require-signin.
Validate Server Health
Use the public URLs printed by the helper:
curl -sf <DEN_WEB_URL>/api/den/health
curl -sf <DEN_API_URL>/health
Inspect logs if health checks fail:
daytona exec "$SERVER_SANDBOX" -- 'tail -120 /tmp/den-api.log'
daytona exec "$SERVER_SANDBOX" -- 'tail -120 /tmp/den-web.log'
daytona exec "$SERVER_SANDBOX" -- 'tail -120 /tmp/den-worker-proxy.log'
daytona exec "$SERVER_SANDBOX" -- 'tail -120 /tmp/den-db-push.log'
When To Use Two Sandboxes
Use two sandboxes when testing cloud behavior end-to-end: server sandbox for Den
and a separate Electron sandbox for the desktop client. This matches production
better than trying to run everything inside one desktop sandbox.
Use this for marketplace install/remove/search/filter, org-managed extensions,
desktop handoff auth, cloud restrictions, and worker proxy flows.
Evidence
Pair this with the daytona-recording-artifacts skill. Server proof should
include health-check output, relevant logs, CDP assertions from Electron, and a
recording or screenshot artifact for human review.
Use daytona-flow-validator for pass/fail. Server health alone does not prove
Electron cloud behavior works.
