Export image to Docker

You may want your build result to be available in the Docker client through docker images to be able to use it in another step of your workflow:

name: ci

on:
  push:
    branches:
      - 'main'

jobs:
  docker:
    runs-on: ubuntu-latest
    steps:
      -
        name: Checkout
        uses: actions/checkout@v3
      -
        name: Set up Docker Buildx
        uses: docker/setup-buildx-action@v2
      -
        name: Build
        uses: docker/build-push-action@v3
        with:
          context: .
          load: true
          tags: myimage:latest
      -
        name: Inspect
        run: |
          docker image inspect myimage:latest
