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.
