docker image outdated schema1 manifest format

Image docker.io/library/xxx uses outdated schema1 manifest format.

Please upgrade to a schema2 image for better future compatibility.

这个问题 是要怎么解决呢 ？

文档这样说：

Update to image manifest version 2, schema 2 One way to upgrade an image from image manifest version 2, schema 1 to schema 2 is to docker pull the image and then docker push the image with a current version of Docker. Doing so will automatically convert the image to use the latest image manifest specification.

Converting an image to image manifest version 2, schema 2 converts the manifest format, but does not update the contents within the image. Images using manifest version 2, schema 1 may contain unpatched vulnerabilities. We recommend looking for an alternative image or rebuilding it.

？？？ 先 pull 下来再 push 上去？

问题是有这个问题，就 pull 不下来。懵逼。

然后说下环境：

Operating System: CentOS Linux 7 (AltArch) OSType: linux Architecture: aarch64 arm 的 docker 。

PS：

比较奇怪的是，重启 docker 或者 偶然的情况下，又不会出现这个问题，同样的 pull 镜像命令。

神奇，更纳闷了。
