push-to-registry

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 to perform the push. GitHub's Ubuntu action runners come with Podman preinstalled. If you are not using those runners, you must first install Podman.

Action Inputs

Input	Required	Description
image	Yes	Name of the image you want to push.
tag	No	Image tag to push. Defaults to latest.
registry	Yes	URL of the registry to push the image to. Eg. quay.io/<username>
username	Yes	Username with which to authenticate to the registry.
password	Yes	Password, encrypted password, or access token with which to authenticate to the registry.

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.
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 action.

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 }}
