ADDED Requirements

Requirement: System monitors tunnel health

The system SHALL periodically check if active tunnel URLs are reachable and mark them as erroneous if not.

Scenario: Healthy tunnel

  • WHEN a tunnel health check is performed on a running instance
  • THEN the system receives an HTTP 2xx response
  • AND the instance status remains "running"

Scenario: Broken tunnel

  • WHEN a tunnel health check is performed on a running instance
  • AND the response is not HTTP 2xx or the request fails
  • THEN the instance is marked with tunnel_error status
  • AND a visual error indicator is displayed in the UI

Requirement: Users can recreate broken tunnels

The system SHALL allow users to regenerate a temporary tunnel for a running instance without restarting the instance.

Scenario: Recreate tunnel

  • WHEN user clicks "Recreate Tunnel" button on an instance with a broken tunnel
  • THEN the system stops the existing cloudflared process
  • AND starts a new cloudflared tunnel
  • AND updates the instance URL
  • AND the new URL is displayed in the UI

Scenario: Recreate tunnel success

  • WHEN tunnel recreation completes successfully
  • THEN the error indicator is removed
  • AND the instance shows as healthy

Scenario: Recreate tunnel failure

  • WHEN tunnel recreation fails
  • THEN the error indicator remains
  • AND an error message is displayed to the user
