Push-to-registry is a GitHub Action for pushing an OCI-compatible image to an image registry, such as Dockerhub, Quay.io, or an OpenShift integrated registry.

This action only runs on Linux, as it uses [podman](https://github.com/containers/Podman) to perform the push. [GitHub's Ubuntu action runners](https://github.com/actions/virtual-environments#available-environments) come with Podman preinstalled. If you are not using those runners, you must first [install Podman](https://podman.io/getting-started/installation).

## Action Outputs

This action produces these outputs which can be used for further processing in different Github action:

`registry-path`: The registry path to which the image was pushed.<br>
For example, `quay.io/username/spring-image:v1`.

## Examples

The example below shows how the `push-to-registry` action can be used to push an image created by the [buildah-build](https://github.com/redhat-actions/buildah-build) action.

```yaml
name: Build and Push Image
on: [push]

jobs:
  build:
    name: Build and push image
    runs-on: ubuntu-latest
    env:
      IMAGE_NAME: my-app
      IMAGE_TAG: latest

    steps:
    - uses: actions/checkout@v2

    - name: Build Image
      uses: redhat-actions/buildah-build@v1
      with:
        image: ${{ env.IMAGE_NAME }}
        tag: ${{ env.TAG }}
        dockerfiles: |
          ./Dockerfile

    - name: Push To Quay
      id: push-to-quay
      uses: redhat-actions/push-to-registry@v1
      with:
        image: ${{ env.IMAGE_NAME }}
        tag: ${{ env.TAG }}
        registry: ${{ secrets.QUAY_REPO }}
        username: ${{ secrets.QUAY_USERNAME }}
        password: ${{ secrets.QUAY_TOKEN }}

    # The output is stored in ${{ steps.push-to-quay.outputs.registry-path }}
```
