image-syncer

image-syncer 是阿里云开发的容器镜像同步工具，可用来进行多对多的镜像仓库同步，支持目前绝大多数主流的 docker 镜像仓库服务 阿里云官方image-syncer 地址

Image-syncer

该项目是受image-syncer启发同样用go语言写的轻量(go还使用的不是太熟练😅)的镜像同步工具。

手动编译

当前系统架构编译

cd Image-syncer
go build -o image-syncer

所有常用系统架构编译

git clone https://gitlab.ayou.ink/IabSDocker/Image-syncer.git
cd Image-syncer
sh build.sh

命令用例

namespace与源仓库一致

[root@luckly ~]# cat config.yaml
# 原仓库
source_repo: "docker.io"
# 目标仓库
target_repo: "localhost:5000"
# 更新后不可删除namespace字段，若不使用namespace字段让其为空即可
namespace: ""
# 要同步的镜像列表
images:
  - "iabsdocker/registry:latest"  
  - "nginx:latest"
[root@luckly ~]# ./image-syncer --config config.yaml
[root@luckly ~]# docker image ls
REPOSITORY                                  TAG               IMAGE ID       CREATED         SIZE
localhost:5000/nginx                        latest            5ef79149e0ec   4 days ago      188MB
nginx                                       latest            5ef79149e0ec   4 days ago      188MB
iabsdocker/registry                         latest            f7b1a4c78949   5 weeks ago     45.3MB
localhost:5000/registry                     latest            f7b1a4c78949   5 weeks ago     45.3MB

自定义namespace字段

[root@luckly ~]# cat config.yaml
# 原仓库
source_repo: "docker.io"
# 目标仓库
target_repo: "localhost:5000"
# 更新后，当启用namespace后同步后的镜像tag将发生变化
namespace: "mytest"
# 要同步的镜像列表
images:
  - "iabsdocker/registry:latest"  
  - "nginx:latest"
[root@luckly ~]# ./image-syncer --config config.yaml
[root@luckly ~]# docker image ls
REPOSITORY                                  TAG               IMAGE ID       CREATED         SIZE
localhost:5000/mytest/nginx                 latest            5ef79149e0ec   4 days ago      188MB
nginx                                       latest            5ef79149e0ec   4 days ago      188MB
iabsdocker/registry                         latest            f7b1a4c78949   5 weeks ago     45.3MB
localhost:5000/mytest/registry   latest            f7b1a4c78949   5 weeks ago     45.3MB

日志相关

镜像同步完成后会统计结果，所有同步失败的镜像会在Failures字段中给出报错信息！！！
