NOTE: The project supports both Python2 and Python3

Prerequisite

Editing image lists

Edit the images.txt of the image repositories for syncing

quay.io/coreos/prometheus-operator=registry.cn-hangzhou.aliyuncs.com/coreos_containers/prometheus-operator
gcr.io/google_containers/pause-amd64

Each line will be one repo definition

source_repo=target_repo Sync the source repo to specific target repo
