# Copy images between registries
|
|
|
|
Multi-platform images built using buildx can be copied from one registry to another without
|
|
changing the image SHA using the [tag-push-action](https://github.com/akhilerm/tag-push-action).
|
|
|
|
The following workflow will first push the image to dockerhub, run some tests using the images
|
|
and then push to quay and ghcr
|
|
|
|
```yaml
|
|
name: ci
|
|
