Github action to mirror docker images between ggml-org and ggerganov

This script mirrors a set of tags from one repository to another. It is designed mirror WITHIN the same registry (ghcr.io in this case), by cross-mounting blobs. This prevents the need to download and re-upload the same data.

Installation

1. Clone this repo
2. Modify sync.py to set your source, target repo and list of tags
3. Modify .github/workflows/docker.yml, uncomment the schedule section
4. Push it to your workflow repo

For example:

• SOURCE_REPO set to ggml-org/llama.cpp
• TARGET_REPO set to ggerganov/llama.cpp

This will copy images from ggml-org --> ggerganov (one-way sync)

NOTE: In our case, the workflow repo and the target repo are different, we will need to add permission to allow the workflow repo to push: Go to https://github.com/users/YOUR_GITHUB_USERNAME_HERE/packages/container/llama.cpp/settings
