业务在上云过程中会遇到Docker容器批量迁移的需求，下面基于开源image-syncer组件将docker镜像批量迁移到华为云SWR容器仓库服务上，支持华为云不同地域的SWR容器仓库互迁，也支持私有容器仓库迁移到SWR服务。

1、下载image-syncer

我这边用的是鲲鹏服务器是ARM架构的，所以image-syncer版本选择了ARM架构的

wget https://github.com/AliyunContainerService/image-syncer/releases/download/v1.3.1/image-syncer-v1.3.1-linux-arm64.tar.gz

英特尔的X86架构服务器用这个

wget https://github.com/AliyunContainerService/image-syncer/releases/download/v1.3.1/image-syncer-v1.3.1-linux-amd64.tar.gz

2、解压

tar -zxvf image-syncer-v1.3.1-linux-arm64.tar.gz

解压后内容如下：

3、以下举例华为云上不同地域的SWR仓库迁移

3.1、获取SWR源仓库账户

登录SWR控制台，在右上角单击“登录指令”，在弹出的窗口中获取登录指令，如下图所示：

docker login -u cn-south-4@TSD4KF8TQSPSSSSSSS -p 123456784fa31fb24df3fc052bca6388e6de4d5ddc1a7654321 swr.cn-south-1.myhuaweicloud.com

登录指令中，cn-south-4@TSD4KF8TQSPSSSSSSS为username；123456784fa31fb24df3fc052bca6388e6de4d5ddc1a7654321为password；
cn-east-4.myhuaweicloud.com为镜像仓库地址。

3.2、获取SWR目的仓库账户

docker login -u cn-north-4@VQRCDRHSWL8AAAAAAAA -p 7654321c40dbaeddec9154277d709e71a1ca2fc6ab791234567 swr.cn-north-4.myhuaweicloud.com

3.3、创建账户配置文件auto.json

将源仓库及目标仓库认证信息写入，示例如下：

{
    "swr.cn-north-4.myhuaweicloud.com": {
        "username": "cn-north-4@VQRCDRHSWL8AAAAAAAA",
        "password": "7654321c40dbaeddec9154277d709e71a1ca2fc6ab791234567"
    },
    "swr.cn-south-1.myhuaweicloud.com": {
        "username": "cn-south-1@TSD4KF8TQSPSSSSSSS",
        "password": "123456784fa31fb24df3fc052bca6388e6de4d5ddc1a7654321"
    }
}

3.4、创建同步镜像描述文件images.json

参数解读：swr.cn-south-1.myhuaweicloud.com/image-syncer/openeuler
镜像仓库地址：swr.cn-south-1.myhuaweicloud.com
组织：image-syncer
容器名称：openeuler
左边是源仓库的地址，右边是目的仓库地址

{
    "swr.cn-south-1.myhuaweicloud.com/image-syncer/openeuler":"swr.cn-north-4.myhuaweicloud.com/test/openeuler",
    "swr.cn-south-1.myhuaweicloud.com/image-syncer/centos":"swr.cn-north-4.myhuaweicloud.com/test/centos",
    "swr.cn-south-1.myhuaweicloud.com/image-syncer/debian":"swr.cn-north-4.myhuaweicloud.com/test/debian",
    "swr.cn-south-1.myhuaweicloud.com/image-syncer/mariadb":"swr.cn-north-4.myhuaweicloud.com/test/mariadb",
    "swr.cn-south-1.myhuaweicloud.com/image-syncer/ubuntu":"swr.cn-north-4.myhuaweicloud.com/test/ubuntu",
    "swr.cn-south-1.myhuaweicloud.com/image-syncer/python":"swr.cn-north-4.myhuaweicloud.com/test/python",
    "swr.cn-south-1.myhuaweicloud.com/image-syncer/golang":"swr.cn-north-4.myhuaweicloud.com/test/golang",
    "swr.cn-south-1.myhuaweicloud.com/image-syncer/redis":"swr.cn-north-4.myhuaweicloud.com/test/redis"
}

3.5、执行如下命令将镜像迁移至SWR。

./image-syncer --auth=./auth.json --images=./images.json --retries=3 --log=./log
