+# 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
+
+on:
+ push:
+ branches:
+ - 'master'
+
+jobs:
+ docker:
+ runs-on: ubuntu-latest
+ steps:
+ -
+ name: Checkout
+ uses: actions/checkout@v2

+ uses: docker/setup-qemu-action@v1
+ -
