Cri Tools
Este proyecto proporciona un conjunto de utilidades de diagnóstico y validación para runtimes de contenedores que implementan la Container Runtime Interface de Kubernetes. Sirve como una interfaz de línea de comandos para interactuar y gestionar ciclos de vida de contenedores, imágenes y sandboxes directamente en una máquina host sin requerir un despliegue de cluster completo.
El conjunto de herramientas se distingue por su enfoque en el cumplimiento de la interfaz y la verificación del rendimiento. Incluye suites de pruebas automatizadas que validan si un runtime se adhiere a las especificaciones de interfaz definidas y maneja la integración de plugins de recursos correctamente. Adicionalmente, proporciona capacidades de benchmarking para medir la latencia y el throughput de las operaciones de contenedores, así como utilidades para inspeccionar el estado del runtime y solucionar problemas de conectividad mediante políticas configurables de reintento y tiempo de espera.
Más allá de la validación central, el proyecto soporta tareas operativas como ejecutar comandos dentro de contenedores activos, gestionar checkpoints de contenedores y monitorear métricas de uso de recursos. También incluye funcionalidad para probar la estabilidad de conexiones de datos en streaming para sesiones interactivas, asegurando que las operaciones de port-forwarding y attachment funcionen como se espera.
