使用image-syncer同步多CPU架构镜像到私有仓库

下载image-syncer

mkdir ~/image-syncers
cd ~/image-syncers
wget https://github.com/AliyunContainerService/image-syncer/releases/download/v1.3.1/image-syncer-v1.3.1-linux-amd64.tar.gz
tar xzvf image-syncer-v1.3.1-linux-amd64.tar.gz

创建 config.yaml

auth:
  registry.hisun.netwarpps.com:
    username: "username"
    password: "xxxxxxxx"
  offlineregistry.example.com:5000:
    insecure: true
images:
  docker.io/library/ubuntu:21.10: registry.example.com/library/ubuntu:21.10
  registry.example.com/library/ubuntu:21.10: offlineregistry.example.com:5000/library/ubuntu:21.10

执行同步

./image-syncer --config config.yaml --arch "arm64" --arch "amd64" --os linux

验证其中一个镜像信息

docker manifest inspect registry.example.com/library/ubuntu:21.10
