中文文档

Synchronize the docker image from one registry to another through github action. For example, synchronize the specified docker image under gcr.io to docker.io.

Usage

Open a new issue, then use the image name to be synchronized as title (The image name needs to be a full name, which means registry and tag cannot be omitted), the content of issue can be empty.

For example: open a new issue with title k8s.gcr.io/kube-state-metrics/kube-state-metrics:latest, Then the github action will automatically pull the image and push it to the xin053 repository, then you can use docker pull xin053/kube-state-metrics:latest command to pull the image.

You can view the synchronized docker images through the link below:

https://hub.docker.com/u/xin053
