Dockerize
Ce projet est une boîte à outils de gestion de processus pour les conteneurs Docker. Il fournit des utilitaires pour superviser les processus de conteneur, rendre des modèles de démarrage, diffuser des journaux et vérifier les dépendances de service.
La boîte à outils inclut un vérificateur de dépendance de service qui bloque le démarrage de l'application jusqu'à ce que les sockets réseau, les points de terminaison web ou les fichiers locaux requis soient disponibles. Elle dispose également d'un moteur de rendu de modèle de configuration pour générer des fichiers d'application à partir de variables d'environnement pendant le processus de démarrage, et un utilitaire de diffusion de journaux qui redirige les mises à jour de fichiers vers la sortie standard en utilisant le polling et la gestion de rotation.
Le système gère en outre les cycles de vie des applications via un superviseur de processus qui enveloppe l'exécution et transmet les signaux système aux processus enfants pour garantir des arrêts gracieux.
Features
- Container Process Supervisors - Provides a specialized supervisor for containers that ensures system signals are forwarded to child processes.
- Runtime Availability Polling - Blocks startup by repeatedly verifying the availability of network sockets, web endpoints, or local files.
- Configuration File Generation - Generates physical configuration files from templates by injecting environment variables during startup.
- Container Configuration Templates - Generates application configuration files from templates using environment variables during the boot process.
- Container Startup Dependency Management - Pauses Docker container startup until required network sockets, web endpoints, or files are available.
- Container Process Management Toolkits - Offers a comprehensive set of utilities for managing process lifecycles, signal forwarding, and service dependencies in Docker.
- Container Signal Forwarders - Intercepts container stop signals and forwards them to child processes for graceful termination.
- Process Lifecycle Management - Wraps application execution to ensure signals are handled correctly and processes are managed in containers.
- Service Dependency Blocking - Provides a mechanism to block application startup until required network sockets, endpoints, or files are available.
- Environment Variable Injection - Injects environment variables into configuration templates during the initial boot sequence.
- Configuration Template Renderers - Creates destination configuration files by processing templates with environment variables and built-in functions.
- Process Lifecycle Wrappers - Wraps application execution as child processes to manage their lifecycle and capture I/O streams.
- Process Supervision - Manages application lifecycles and signal forwarding inside containers to ensure graceful shutdowns.
- Service Availability Checkers - Blocks application startup until required network sockets, web endpoints, or local files are available.
- Service Availability Polling - Verifies network availability by polling sockets or web endpoints to block application startup until dependencies are ready.
- Startup Dependency Verifications - Blocks application startup until required local files exist on disk to ensure dependency readiness.
- Log File Streaming - Monitors log files via polling and pipes updates to standard output while handling file rotations.
- Container Log Streaming - Pipes log file updates from within a container to the standard output stream using polling.
- Container Management - Simplifies running applications inside containers.
- Deployment and DevOps - Tool for configuring and running applications in Docker containers.
