Docker Gen
docker-gen ist ein Konfigurationsgenerator, der Textvorlagen mithilfe von Metadaten, die aus Docker-Containern abgerufen werden, in Dateien rendert. Er fungiert als Service-Discovery-Tool und vorlagenbasierter Orchestrator, der Container-Zustände und Umgebungsvariablen auf spezifische Zielpfade auf dem lokalen Speicher einer Host-Maschine abbildet.
Das Tool automatisiert die Aktualisierung von Reverse-Proxy- und Service-Discovery-Einstellungen in Echtzeit, während Container gestartet, gestoppt oder umbenannt werden. Es verwendet sequentielle Vorlagenverarbeitung und Hilfsfunktionen, um Container-Daten zu filtern und zu sortieren, wodurch eine stabile und konsistente Konfigurationsausgabe gewährleistet wird.
Features
- Configuration File Generators - Generates configuration files for reverse proxies and service discovery by rendering templates based on container metadata.
- Template-Based Code Generators - Renders text templates into configuration files by injecting dynamic metadata retrieved from a container orchestration API.
- Container Metadata Retrieval - Fetches current container state and environment variables from the Docker socket to use as template data.
- Container Metadata Configuration Generators - Creates configuration files for services by automatically pulling metadata from running Docker containers.
- Service Discovery - Maps network addresses and ports for a collection of Docker containers into a readable format for other tools.
- Container-Driven Rendering - Uses container metadata to fill out text templates and generate the resulting files without manual editing.
- Dynamic Reverse Proxies - Updates reverse proxy settings in real time as Docker containers are started, stopped, or renamed.
- Sequential Multi-Job Template Executors - Executes a defined series of templates in a specific order to produce a consistent set of output files.
- Template Functions - Filters and sorts container data into stable output using standard text templates and integrated helper functions.
- Configuration Logic Functions - Uses custom logic functions within templates to sort and filter container lists for stable configuration output.
- Multiple Template Job Pipelines - Generates multiple sequential configuration files using template logic and container data.
- Container Management - Generates configuration files from container metadata.
- In-Container Tooling - Generates configuration files based on container metadata.
