- Remove complex systemd service and startup script approach - Use direct container setup in service_bootstrap() like Phoenix RTOS - Add setup_nodered_container() function with msg logging - Keep ONE_SERVICE_PARAMS for reconfigurability - Simplify service_install() to just pull image and configure console - Use msg info/error for consistent logging - Add container health check with retry loop
- Add tests.yaml configuration file - Add comprehensive test suite matching actual appliance: * Docker installation and service status * Node-RED container image availability (nodered/node-red:latest) * Data directory existence (/data) * Container running status (nodered-app) * Container responsiveness * Container restart policy (unless-stopped) * Port mapping (1880:1880) * Volume mapping (/data:/data) * oneapps MOTD verification (required test) - Uses standard RSpec framework (lib/community/app_handler)
The user_inputs should be a dictionary (key: value), not an array. Changed keys to lowercase with oneapp_ prefix to match OpenNebula conventions: - CONTAINER_NAME -> oneapp_container_name - CONTAINER_PORTS -> oneapp_container_ports - CONTAINER_ENV -> oneapp_container_env - CONTAINER_VOLUMES -> oneapp_container_volumes Updated inputs_order to match the new uppercase context variable names.
Set ONE_SERVICE_VERSION='latest' instead of leaving it empty. This fixes the build script metadata.
Use proper version number '1.0' instead of 'latest' for the appliance version.
- Add wait period for contextualization to complete (60s initial + up to 120s for Docker) - Fix template parsing error in volume mount test (use single quotes for docker format) - Fix app_handler.rb context escaping (add quotes around context value and use consistent escaping) The tests now properly wait for Docker service to start and the Node-RED container to be created before running validation checks.
- Fix metadata.yaml structure to match test framework requirements - Change :os: from array to hash with :type and :base - Change :hypervisor: from array to single value - Add :context: section with container parameters - Add 1️⃣ section with template configuration - Add :infra: section with disk_format and apps_path - Add generated context.yaml for Node-RED appliance Tests should pass successfully with these changes.
