Multiple image build/push

This action is compatible with docker/metadata-action, which allows you to generate multiple tags.

      - name: image metadata
        id: meta
        uses: docker/metadata-action@v4.0.1
        with:
          images: repo/image
          tags: |
            type=ref,event=branch
            type=ref,event=pr
            type=semver,pattern=v{{version}}
            type=semver,pattern=v{{major}}.{{minor}}
            type=semver,pattern=v{{major}}
            type=sha,prefix=${{ steps.branch-name.outputs.short_ref }}-
            
      - name: Kaniko builder
        id: kaniko
        uses: bellrocktech/kaniko-action@main
        with:
          registry: reg.example.com
          images: ${{ steps.meta.outputs.tags }}
          tag_with_latest: true
          path: ./context/path
          username: ${{ secrets.REG_USERNAME }}
          password: ${{ secrets.REG_PASSWORD }}
          cache: true
          cache_url: reg.example.com/cache/image

Inputs

You can either use the image and tag inputs, OR the images input.

For compatibility with docker/metadata-action, you can use the images input and the expected format is a line separated list of image:tag pairs.

images: |
  repo/image:tag1
  repo/image:tag1
