OCI Mirror

Container and OCI Image Mirror.

oci-mirror lets you mirror container images or any other oci artefact between registries. It is designed to run on a regular basis, as a CronJob in kubernetes for example. Under the hood it uses go-containerregistry to copy images directly from one registry to another.

Configuration

Configuration is done with a yaml configuration, defaults to oci-mirror.yaml.

Quickstart

First create a oci-mirror.yaml which matches your needs, then run it with the following command:

docker run -it -v $PWD/oci-mirror.yaml:/oci-mirror.yaml --rm ghcr.io/metal-stack/oci-mirror mirror

Kubernetes

There is a sample deployment manifest available, you can simple run:

kubectl apply -f deploy

TODO

• support purging
• eventually support http(s) artifacts to be stored as OCIs
• ~~~support Regex Match for image tags~~~
• store a OCI artifact which reflects all stored images ?
