            !!!请使用标准镜像格式
            1. 镜像要带tag,如nginx,请写为nginx:latest
            2. 标题不重要,issue描述部分,每行一个镜像不要有其他内容,你可以直接更新你的issue

            ❌ 镜像同步失败，请检查以下几点：
            - 源镜像是否拼写错误？
            - tag 是否存在（如 `latest`、`1.21`）？
            - 该镜像是否为公开可拉取的镜像？
            - 若为私有镜像，请确认目标 registry 有访问权限

            可参考 logs：
