## 示例

- 将 redis 的 arm64 和 amd64 镜像构建成一个多架构镜像

```shell
# docker manifest create harbor.cncfstack.com/library/redis:6.2.6-multi harbor.cncfstack.com/library/redis:6.2.6-amd64 harbor.cncfstack.com/library/redis:6.2.6-arm64
Created manifest list harbor.cncfstack.com/library/redis:6.2.6-multi
```

构建完成后，可以使用 `docker manifest inspect` 查看多架构镜像信息

```shell
# docker manifest inspect harbor.cncfstack.com/library/redis:6.2.6-multi
{
   "schemaVersion": 2,
   "mediaType": "application/vnd.docker.distribution.manifest.list.v2+json",
   "manifests": [
      {
         "mediaType": "application/vnd.docker.distribution.manifest.v2+json",
         "size": 1573,
         "digest": "sha256:3991cfe7ed07a7080c79a3b52e38e81caf13f9aa013b0bf588807f4637176515",
         "platform": {
            "architecture": "amd64",
            "os": "linux"
         }
      },
      {
         "mediaType": "application/vnd.docker.distribution.manifest.v2+json",
         "size": 1572,
         "digest": "sha256:6c1a95df60f12a3b014fa5c85a9c04e742eb2686db2a9f212d49974188ebf0ec",
         "platform": {
            "architecture": "arm64",
            "os": "linux",
            "variant": "v8"
         }
      }
   ]
}
```

然后使用 `docker manifest push` 将多架构镜像信息推送远程仓库

```shell
# docker manifest push  harbor.cncfstack.com/library/redis:6.2.6-multi
sha256:89762437568f959988bcd9aefe08a8b41d6031defac406a3d9e0281efe07177a
```
