Not able to copy file in docker file which is downloaded in github actions

Question

I can able to see the .pkl which is downloaded using actions/download-artifact@v3 action in work directory along with Dockerfile as shown below,

When I try to COPY file inside Dockefile, I get a file not found error.

How to copy the files inside docker image that are downloaded(through github actions) before building docker image?

Here is doc from github on docker support, but I didn’t get exactly how to solve my issue. Any help would be really appreciated!!

Dockerfile:

name: Docker - GitHub workflow

env:
  CONTAINER_NAME: xxx-xxx

on:
  workflow_dispatch:
  push:
    branches: ["main"]
  pull_request:
    branches: ["main"]


permissions:
  id-token: write
  contents: read

jobs:
  load-artifacts:
    runs-on: ubuntu-latest
    environment: dev
    env:
      output_path: ./xxx/xxx_model.pkl
    
    steps:
      - uses: actions/checkout@v3

      - name: Download PPE model file
        run: |
            az storage blob download --container-name ppe-container --name xxx_model.pkl -f "${{ env.output_path }}"
            
      - name: View output - after
        run: |
          ls -lhR
      
      - name: 'Upload Artifact'
        uses: actions/upload-artifact@v3
        with:
          name: ppe_model
          path: ${{ env.output_path }}

  
  build:
    needs: load-artifacts
    runs-on: ubuntu-latest
    env:
      ACR: xxxx
      
    steps:
      - uses: actions/checkout@v3

      - uses: actions/download-artifact@v3
        id: download
        with:
          name: ppe_model
          # path: ${{ env.model_path }}

      - name: Echo download path
        run: echo ${{steps.download.outputs.download-path}}
      
      - name: View directory files
        run: |
          ls -lhR -a

      - name: Build container image
        uses: docker/build-push-action@v2
        with:
          push: false
          tags: ${{ env.ACR }}.azurecr.io/${{ env.CONTAINER_NAME }}:${{ github.run_number }}
          file: ./Dockerfile

In your workflow file, you’re not specifying the context:

      - name: Build container image
        uses: docker/build-push-action@v2
        with:
          push: false
          tags: ${{ env.ACR }}.azurecr.io/${{ env.CONTAINER_NAME }}:${{ github.run_number }}
          file: ./Dockerfile

By default, that means that docker/build-push-action choose a git context. That will re-clone your repository… without your model.

The fix, then, is to specify a path context, like this:

      - name: Build container image
        uses: docker/build-push-action@v2
        with:
          context: .
          push: false
          tags: ${{ env.ACR }}.azurecr.io/${{ env.CONTAINER_NAME }}:${{ github.run_number }}
          file: ./Dockerfile
