Docker Gc
docker-gc 是一个 Docker 主机垃圾回收工具，旨在通过自动删除已退出的容器、未使用的镜像和悬空卷来回收磁盘空间。它充当资源清理器，通过对孤立或非活动容器资源的生命周期管理来优化主机存储。
该实用程序通过保留每个存储库中最近的镜像数量来管理镜像保留，同时删除旧版本。它采用可配置的宽限期来确定镜像和容器何时有资格被删除，并支持基于模式的排除以防止特定资产被删除。
该工具涵盖了广泛的维护操作，包括用于识别删除候选者的状态驱动资源选择，以及清理临时工件以维护系统健康。
Features
- Unused Container Resource Pruning - Provides a CLI tool for removing dangling images, stopped containers, and unused volumes to reclaim host disk space.
- Container Maintenance - Automates the cleanup of temporary Docker artifacts to maintain the health of development and production servers.
- Container Image Retention Policies - Implements chronological pruning of Docker images while respecting minimum retention counts per repository.
- Container Storage Optimization - Prevents Docker host disk exhaustion by cleaning up orphaned containers and volumes.
- Container State Filtering - Identifies candidates for removal by filtering for specific states like exited containers or dangling volumes.
- Container Garbage Collection - Provides automated garbage collection for unused container images, exited containers, and dangling volumes.
- Dangling Volume Cleanup - Purges dangling Docker volumes and unused resources to prevent host disk space exhaustion.
- Repository-Aware Image Retention - Tracks the most recent images per repository to maintain a minimum count of preserved builds.
- Unused Image Pruning - Removes unused or old Docker images to reclaim disk space on the host system.
- Container Lifecycle Cleanup - Automatically deletes exited Docker containers based on age or specific grace periods.
- Docker Engine API Clients - Utilizes the Docker Engine API to programmatically query and delete host containers, images, and volumes.
- Docker - Purges inactive Docker resources based on configurable grace periods and retention rules.
- Image Version Retention Management - Preserves a minimum number of recent Docker images while deleting older versions.
- Image Version Retention - Keeps a specified minimum number of the most recent images for each repository to avoid deleting active versions.
- Resource Identifier Matching Protections - Prevents specific Docker resources from being garbage collected by matching name patterns or unique identifiers.
- Resource Deletion - Provides configurable grace periods to ensure only resources older than a specific threshold are deleted.
- Container Utilities - Automated garbage collection for containers and images.
