A Go CLI tool that synchronizes Docker images between registries supporting Docker Registry V2, such as Docker Hub, Quay.io, Harbor, and Alibaba Cloud ACR. It performs fast, memory-only, incremental many-to-many syncs without requiring a Docker daemon.
Use cases
- sync docker images between registries
- mirror images from docker hub to aliyun acr
- copy container images to harbor
- bulk migrate docker images to a private registry
- incremental image synchronization in ci pipeline
- replicate images across multiple registries
When to choose
- you need many-to-many image replication across V2-compatible registries
- you want fast sync without disk storage or a Docker daemon
- you need automatic retries and incremental sync for CI/CD image mirroring
When to avoid
- your registries do not implement Docker Registry V2
- you need full image building or scanning, not just syncing
- you prefer a GUI-based registry management tool
