| # Copy images between registries
 | |
| 
 | |
| [Multi-platform images](https://docs.docker.com/build/building/multi-platform/)
 | |
| built using Buildx can be copied from one registry to another using the
 | |
| [`imagetools create` command](https://docs.docker.com/engine/reference/commandline/buildx_imagetools_create/):
 | |
| 
 | |
| ```yaml
 | |
| name: ci
